AI can now help distinguish between straight and lateral back raises by watching a video

Science is an important but less popular part of sport. We as viewers often overlook the techniques employed by players in the excitement of enjoying the spirit of the game. However, a team’s support staff are eager to dig into the finer details. For example, think of cricket. While most viewers are interested in how many runs a batsman made, the support team analyzed batting and bowling techniques and other minute details, enlisting the help of analysis technology. Even the most accurate calculations have room for error. To avoid these small mistakes, researchers are now turning to artificial intelligence (AI).

During a cricket game, a batter facing a fast bowler must make a split-second decision about the backlift – whether to go straight or sideways. Now imagine that the technology is improved in a way that it can support the support staff or even that [players]( in identifying the issues. In their latest study, published in Scientific ReportsUsing artificial intelligence, researchers at the University of Johannesburg have developed a deep-learning computer vision model that can detect straight backlift batters from laterals, and only with video.

“This study offers a way forward in automatic player pattern recognition and motion capture, making it less challenging for sports scientists, biomechanists and video analysts working in the field,” the report suggests.

Using this technology, coaches may be able to provide more detailed feedback to players. It can also help identify players with lateral backlift components, such as legendary cricketer Sir Donald Bradman, who pioneered the lateral backlift. “The beauty of deep learning in AI is that you don’t have to tell the AI ​​what to look for,” he says to learn Co-author Tevin Moodley, PhD student at the University of Johannesburg.

Researchers found that inexperienced batsmen often instinctively use a lateral back raise. “What we’ve found is that unless young players are coached using traditional methods, they don’t pick up the racquet directly. You pick up the racket from the side. This indirectly suggests that a straight back lift is not a natural movement,” said Prof. Habib Noorbhai, another author of the article.
