I am trying to implement a paper of human activity recognition, I am just started after specified the steps of the system. I found two points that I did not understand
1- calculate the normalized bounding box coordinate?!
2- If I going to use background subtraction to get silhouette, how can I get silhouette features, I found that there are many types of local features (blob, corner, region of interest) what the difference among these
Thanks a lot
