The sprint bike in the "hardest hit area", the top ten stimulant in sports, is the most typical.

  Tencent Sports News Recently, Wang Hongni, a famous triathlete in China, was found to have used illegal drugs and was banned for two years. The triathlete, which is considered as a "pile of medicine cans", was once again pushed to the forefront of public opinion. Looking at all kinds of sports in sports, ten sports are the "hardest hit areas" for doping. Although the anti-doping organizations keep conducting targeted inspections, they are still banned repeatedly!


  short-distance run


  Doping is the best way to improve the athletes’ instantaneous physiological function, so in the sprint events that need explosive power most, doping incidents are repeatedly banned, and many of those big stars who are suddenly in the clouds are later laid on the altar. The most typical example is that at the Seoul Olympic Games in 1988, Ben Johnson won the men’s 100m gold medal in 9.79 seconds and broke the world record. However, in the subsequent urine test, Ben Johnson was found to have taken synthetic steroids. In addition, gatling and Montgomery, two men who had challenged the world record, were also banned for two years. Jones, a famous American sprinter after Cojna, was also banned for taking steroids and returned to the Olympic gold medal. Ironically, Cojna, the greatest athlete in the history of women’s sprint, was also suspected of using stimulants and leading to her early death, so she still could not bury her body after her death, but had to undergo an autopsy to get her innocence back!


  Tour de France:


  Whether the Tour de France will survive or not is a hot topic in the sports field some time ago, because this dirty sport is challenging the purity of sports. International Olympic Committee President Rogge said that bicycles will not be excluded from the Olympic Games for the time being, which is already lenient. Armstrong, an American legendary hero known as "Forrest Gump" in reality and winner of the seven-time Tour de France, has created countless glories in his sports career, and his story of overcoming cancer and reaching the peak has inspired countless people today. But less than a year after his retirement, it broke the news that he had taken stimulants many times in the competition. For a time, the controversy about whether Armstrong was a lonely hero or a drug champion spread all over the world. Landis and ulrich were even worse than Armstrong. They were banned and deprived of the greatest honor they had ever won. In particular, Landis, an American, keeps going to court to prove his innocence, but it is useless for him to keep his mouth shut in the face of scientific evidence.


  strong and handsome


  Although this event is not an Olympic event, it has become a frequent doping event because of its good promotion in various countries, great visual impact and more commercial intervention. Bodybuilders need to stimulate their muscles, so some athletes should often take some so-called tonics to make their muscles develop. According to the statistics of the Anti-Doping Committee of the Chinese Olympic Committee for many years, the number of times bodybuilders tested positive for drugs is among the top three every year. Just this year, the decision on punishing bodybuilder Jiang Xi for violating the prohibition of doping was issued, and Jiang Xi was suspended from participating in national bodybuilding activities for two years from July 21, 2006 to July 20, 2008.


  There are many incidents of taking medicine in swimming, and many famous big-name stars are not immune from negative rumors. The most typical example is the Australian flying fish "Thorpe storm", which was first stirred up by the French newspaper L ‘Equipe. The newspaper L ‘Equipe reported that a doping test in May last year showed that Thorpe’s testosterone and luteinizing hormone obviously exceeded the standard, and these hormones acted like steroids, which could obviously improve athletes’ performance. Thorpe denied this, and was obviously greatly stimulated, so that at the press conference, what people saw was not the torpedoes in the past, but more like a sad and helpless child. It was not until this year that the Australian Olympic Committee cleared Thorpe. China women’s swimming team was also troubled by doping. In 1994, the glory of the World Swimming Championships was attacked by some foreign media for taking banned drugs. In 2000, Wu Yanyan, a famous Chinese athlete, tested positive for drugs and was banned for four years, missing the Olympic Games.


  weightlifting


  There are countless doping incidents in weightlifting, and a large number of lesser-known athletes are banned every year. Of course, well-known athletes often try their own laws. Mutlu of Turkey was once called a "weightlifting prodigy". At the Atlanta Olympic Games in 1996, Mutlu, 23, set a new world snatch record and easily won his first Olympic gold medal with an advantage of 7.5 kilograms ahead of the second place. At the Sydney Olympic Games in 2000, Mutlu, a "pocket strongman", was in full swing, not only easily defending his title, but also breaking three world records in snatch, clean and jerk and total score. At the 2004 Athens Olympic Games, Mutlu, 31, became a weightlifter who won three consecutive Olympic titles. However, in the 2005 European Championship, Mutlu was found to have used Nuolong and was banned, which also cast a shadow over the veteran’s declining state to participate in the Beijing Olympic Games.


  wrestling


  Wrestling emphasizes the use of strength and physical contact, so doping incidents are also common in this project. Domestically, Gao Yanzhi, a wrestler from Shandong Province, was suspended for two years for taking a diuretic, a prohibited drug, after testing in Athens Olympic Games. The foreign example is even more shocking. American male wrestler Benoit killed his wife and son because he took too many steroids! This steroid can strengthen muscles after taking it, but it can also cause emotional outbursts such as paranoia, depression and steroid rage. Therefore, the police said that they thought that Benoit was taking stimulants, which led to the whole person’s emotional loss of control and eventually violence.


  triathlon


  From the name "triathlon", it is not difficult to see the fierce competition. Only "iron man" can laugh at the end, and doping is undoubtedly the best tool to turn "man" into "iron man". On July 1st, 2005, the Swiss Olympic Committee announced that McMahon, a Swiss female triathlete and winner of the 2000 Sydney Olympic Games, had been found to have used the illegal drug EPO. McMahon admitted that she had taken stimulants, but she argued that it was because she needed stimulants to treat her illness, not to improve her athletic performance. Wang Hongni, the champion of the Asian Games in China, was declared unqualified by the triathlon official website on October 9th, which made the list of doping in this event filled with the names of China people.


  shot


  As a strength-oriented throwing event, many athletes in the shot put competition use illegal drugs at risk. During the Athens Olympic Games, Yong Quest, chairman of the International Olympic Committee Medical Committee, revealed in Athens that Russian player Korzalenko, who won the women’s shot put championship in this Olympic Games, failed the doping test! Korzalenko was deprived of his gold medal in the indoor track and field championships in 1999 because of doping. This is the second time he has committed a crime against the wind. Hunter, the husband of American female sprinter Jones, was found to have taken banned drugs such as steroids after the 1999 World Championships, and then he was banned from the IAAF for two years, so he missed the Sydney Olympic Games in 2000.


  Rugby


  Known as the most antagonistic sports football doping scandal in the world, Ha Silei, a retired American professional football player, revealed that according to his estimation, at least half of the players in the league were taking steroids before drug testing began in the late 1980s. He said, "If you don’t eat, you can’t be as strong as others and can’t keep up with their speed. This is the only reason why we take medicine, because the competition is too fierce. I was still taking steroids six weeks before I decided to end my career. " Keith Jones, an NBA Rockets trainer, said in a recent interview that during his years as a trainer, he saw too many football players taking steroid stimulants.


  Tennis:


  It is reasonable to say that the effect of doping in tennis, which emphasizes the change of skills and lines, will not be too great. However, with the prevalence of strength-playing, there are also many drug users in tennis. Poorta and canas have unfortunately become "leaders" in their respective fields. In addition, this list also includes Bulgarian beautiful girl Karatancheva. Nowadays, the names of Poorta and Karatancheva are rarely mentioned again, but canas has made a high-profile comeback after the suspension period, becoming one of the few players who have defeated Swiss ball king Federer in a row in recent years.

China smart car research selected for CVPR2023! A new method for 3D lane line detection, produced by Mimo Zhixing.

CVPR 2023, one of the top three computer vision conferences, was exposed in the paper of China Smart Car Company.

Domestic autonomous driving companyHao mo zhi hangThe paper Bev-Lane Det: A Simple and Effective 3D Lane Detection Baseline submitted by the technical team of its Artificial Intelligence Center was successfully selected into CVPR2023.

What problems should the new research solve?

3D lane detectionAs a hot topic in the field of automatic driving, it plays a vital role in vehicle routing. In the past, related technologies were often difficult to be applied because of its complex spatial transformation and inflexible representation of 3D lanes.

Faced with these problems, Millie independently developed an efficient and robust monocular 3D lane detection, referred to as:BEV-LaneDet.

In BEV-LaneDet, Millimeter team first converted all the internal and external parameters of the input image into unified internal and external parameters through the virtual camera, which ensured the consistency of the spatial relationship of the front cameras in different vehicles and effectively promoted the learning process.

Moreover, Millimeter Team uses feature extractor to extract the features of the front view image, and proposes a simple but effective 3D lane representation, which is called "Key-Points Representation". This module is more suitable for representing complex and diverse 3D lane structures.

On this basis, inspired by FPN, Millicent team also designed a lightweight and chip-friendly spatial transformation module called "Spatial Transformation Pyramid", which is a fast multi-scale spatial transformation module based on VPN, mainly responsible for the transformation from front view features to BEV features.

Finally, the team predicted the lane on the plane tangent to the local road surface, divided the local road surface into s1×s2 grids, predicted confidence, embedding for clustering, lateral error offset and the height of each grid, and used fast clustering method to fuse the results of each branch in reasoning to obtain 3D lanes.

How did BEV-LaneDet perform?

Through the above methods, the F1-S?core of BEV-LaneDet can reach 185FPS on the OpenLane dataset, which is 10.6% higher than the current SOTA.

BEV-LaneDet can also lead the current SOTA method by 4.0% in the performance of Apollo 3D Lane Synthetic.

At present, Mimo Zhixing is the first echelon player in domestic self-driving mass production, and the paper written by its technical team BEV-LaneDet was selected for CVPR, which is actually the embodiment of the technical strength behind the commercial progress.

At present, HPilot has iterated three generations of products, and has achieved mass production on nearly 20 models of Wei brand, tank, Haval, Euler, Great Wall Gun and other brands. In the future, passenger cars equipped with Millimeter-assisted driving products will reach millions of orders of magnitude. As of February 2023, the mileage of user-assisted driving has exceeded 35 million kilometers. NOH, the first city in China that can land on a large scale, has also reached the delivery status with its software sealed.

In addition, the terminal logistics automatic delivery vehicle has initially completed the commercial closed loop, delivering more than 1,000 units, and the delivery order volume of the terminal logistics automatic delivery vehicle Little Magic Camel series has also exceeded 160,000, and the commercialization process is accelerating in an all-round way.

Introduction to CVPR

IEEE (Institute of Electrical and Electronics Engineers) CVPR (Conference on Computer Vision and Pattern Recognition) is one of the three top conferences in the field of computer vision and pattern recognition.

The main content of the conference is computer vision and pattern recognition technology. CVPR is the world’s top computer vision conference (one of the three top conferences, the other two are ICCV and ECCV). In recent years, there are about 1,500 participants every year, and the number of papers collected is generally about 300.

CVPR has strict employment standards. According to CVPR officials, CVPR2023 received a total of 9,155 papers, a record high, and the organizing committee finally hired 2,360 papers, with an acceptance rate of 25.78%.

CVPR is also the witness of major changes in the field of AI vision. The current wave of AI driven by deep learning originated from Hinton’s blockbuster in CVPR Challenge.

Real Madrid, the three giants competing for the Champions League, did a big job in Paris, and tuchel began to learn Spanish.

Although tuchel left Chelsea in September, the 12 points he got for the team still helped Chelsea a lot. Porter only got 22 points for Chelsea within a few months after he took office. Tuchel, who helped Chelsea win the Champions League, is still at home, but many big clubs still want his guidance. The season is coming to an end, and which team tuchel will join next has become a topic of concern.

As far as the current news is concerned, only three teams in tuchel are likely to be joined by tuchel, including La Liga powerhouse Real Madrid, French powerhouse Barley and Premier League Hotspur. Among the three teams, Greater Paris is a team coached by tuchel. Its Champions League record and the strength demonstrated during the construction of the team have once again attracted the attention of the management of Greater Paris, and the Qatari boss also wants to invite tuchel back. Campos, who has an ambiguous relationship with Garti, has no big view on this issue.

Despite the good performance of Tottenham Hotspur this season, Kong Di’s departure is basically inevitable, and the two have already embarked on the journey of changing coaches early. At present, there are mainly two candidates, Pochettino and tuchel. Although Pochettino once coached Tottenham Hotspur, it has become an obstacle to coaching again. On the contrary, tuchel is more likely to join the team. Just as far as tuchel’s personality is concerned, it’s difficult to get in touch with the management of Tottenham Hotspur, and it’s unlikely that he will choose Tottenham Hotspur. After all, the character of Tottenham boss Levi is well known in the Premier League and even in the world football.

As for Real Madrid, it is different. Ancelotti still has some opportunities to coach. If the team can win the Champions League again this season, then he may stay, but if he can’t do this, his departure is inevitable. According to Spanish media reports, tuchel ranked first in the selection of Real Madrid’s coaching position, and tuchel himself is now taking the initiative to learn Spanish. In order to prepare for the next step of coaching Real Madrid, just wait patiently for the end of Ancelotti.

There are so many famous stars in European football, and they almost take turns to coach the major clubs, and tuchel, the coach who won the Champions League, has naturally become the target of everyone’s pursuit. Besides him, Pochettino and Zidane are the focus of team competition in the summer transfer period, but tuchel has a more obvious advantage than others. The reason for his withdrawal from Chelsea is not his personal record, but his harmonious relationship with the management, and there are not many problems with his coaching ability.

What are the use of face recognition technology?

In recent years, artificial intelligence has developed rapidly, especially human face recognition technology, is increasingly widely used in daily life. After entering the 21st century, China Electronic Technology has developed rapidly in just decades, and it is inseparable from the promotion of scientific and technological talents. From human beings enter the steam era, then go to the electrical age, human beings have begun to develop rapidly, and science and technology enters the era of large bombings. Technical application makes us live more fast, efficient, intelligent.

Today mainly introduces people’s face recognition technology, face recognition system has a wide range of applications: face recognition, face recognition, banned tarthen system, face recognition monitoring management, face recognition computer security, face recognition photo search , Face recognition, registration, face recognition ATM wit, video alarm system, face recognition prison intelligent alarm system, face recognition RFID intelligent customs clearance system, face recognition public security criminal pursuit of intelligent alarm system and so on. If the Alipay brush is paid, the "safe city" built by the public security is arrested in the escape criminals, brushing the face into the community, etc. is the application of face recognition technology.

Scope of application: park, factory, supermarket, community square, conference center, sports venue, school, hospital, residential area, commercial street, large-scale farm market, etc. Important parts, hotels, restaurants, catering, entertainment venues Monitoring recording purposes for indoor and outdoor surveillance of the lobby entrance, elevator and other major channels.

Face capture and tracking

Face capture refers to a frame in a frame of an image or video stream and separating portraits from the background and saves it automatically. Portrait tracking refers to the use of portrait capture techniques that automatically tracks it when the specified portrait is moving within the range of the camera.

Face recognition alignment

Face recognition is divided into two comparisons and search formulas. The verification is that the portraits of the captured or the specified portrait have been logged in the database. Remember that a certain object is determined to be the same person. Searching comparison means searching for searching for a specified portrait from all portions registered in the database.

Face modeling and search

The system can model the portable data of the library to extract the characteristics of the face and save it into the database (face feature file) to the database. When performing a face search (search formula), the specified portrait is modeled, and it will be identified compared to the templates of all people in the database, and ultimately list the most similar person according to the compared similar value. List.
