I need some software to analyze some videos. I am trying to measure the change in area of a region through time. This does not have to be real time, but post recording. Not sure what my options are. Here is an example clip. [y]mH59ssD4k_c[/y] Background: I study chromatophores (the things changing shape in the video) in cuttlefish. These organs are responsible for their camouflage abilities. We study how they are controlled, their development and developmental rules, and behavioral uses. I would really appreciate your help!
