This program is built with the idea of building layer by layer elliptical and circular tracker around human and football in picture or image file. this program is built by me and I have also uploaded the program to my github account at links - 

https://github.com/pritam-code-ai/Pritam_AI_code_in_python_1/blob/master/changed_graphical_tracker/yolo.py 

and 

https://github.com/pritam-code-ai/Pritam_AI_code_in_python_1/tree/master/changed_graphical_tracker 

.

It allows the user to build an output image as multi-layered elliptical tracker around lower part of human and circular multi layered tracker around football using opencv python library, yolo-v3 weight file, yolo-v3 configuration file and yolo-v3 label names file. The output image or picture file is like shown in football or soccer video analysis in tv.
