I tried several of the examples like multi_color_blob_tracking and tf_person_detection_search_whole_window with several different background.
I am running them on full screen: VGA framesize and 640x480 windowing. The H7 accurately tracks an object/person that is in the middle of the screen, but as soon as it gets leaves the center of the screen, the object/person starts being tracked differently. In the case of multi_color_blob_tracking smaller parts of the object are tracked, and in the case tf_person_detection_search_whole_window the person is less likely to be recognized.
This is incredibly noticeable as the object/person gets near the edge of the screen to the point where it is unusable. Why isn’t the same object that is the same distance away, fully in frame being tracked poorly when it’s not in the center of the screen?!
