(Apply only if you have a similar experience. I will check work before hire) I have attached the required files. Please check before you apply. I will be providing you with a video of a Badminton match. You need to correctly detect heatmap ( completed). And divide heatmap into different zone as per the present of footstep in each zone. Zonewise heatmap display how much % time player stayed in different part of the court. I am able to divide court into 4 boxes and display heatmap. But need more zonewise heatmap as in image.
