Using back projection might work. The basic idea is to transfer the reference fish image from rgb to HSV Calculate the HS 2D histogram of the reference fish image. Turn the histogram into a probability...

You mean that he tracks fish using KLT but he doesn't recognize them ? That's not very useful in our case indeed. It's quite interesting to have your opinion on that because I don't and will not have...

Very useful comment @sammy , I guess it's better to use texture descriptors in our case, which one you think might be better here ?

First, in the video they say they use KLT=lucas-kanade tracker. Second: between tracking and recognition is a huge complexity difference - the first one is an hour of work. Finally, I would say that...

About that video, my guess is that it is tracking the eye of the fish by detecting the eye as a semi-circular blob. Meaning, no fish recognition is done, it is just following shapes that "kind of" look...

OK @Rui Marques, I exchanged some mails with the guy who made the app on the video. He says that he simply used this implementation of KLT : http://www.ces.clemson.edu/~stb/klt/ And just changed...

In my opinion SURF and similar algorithms will not work well in this case because of distortions made by the water and glass and because the live fish appearance changes too much - the fish will likely...
