Share your ideas and feedback in the comments section below and lets discuss. Once the DRS has been requested by the on field captain, technologies such as HotSpot and Snicko (BBG Sports) can confirm the initial concern of the appeal, whether or not a batsmen has hit the ball, and then it is Virtual Eye's ball tracking which advises the 3rd Umpire - who uses the information to either uphold or overturn the decision. Object detection is similar to an image classification problem, but with an additional task (also identify the location of an object), a concept known as location. Then, then, I will discuss the alternative approach to sliding window. Ball Tracking makes the game more exciting and gets us all on the edge of our seats whenever a decision is reviewed through the DRS. As you can see here, the location of the object is represented by a rectangular box which is popularly known as a Bounding Box.. Bounding Box represents the coordinates of the object in an image. , although once filmed, data can be shared to teammates on Android as well. So next, I will discuss the alternative approach to the sliding window. These are the few challenges we must know before tracking a fast moving ball in a cricket video.
