We are running a research on cave dwelling Arctic charr in Iceland. we have pit-tagged the fish, but sometimes they loose their tags. We have however photographs. We have manually managed to identify the same individuals based on photographs, using the patterns of the dots on the side of the fish. This is a lot of work. Does anyone know of a good program that could do this for us?

Hi Bjarni,
I looked into this for our fish some time ago and even if I did not end up using the technique, here is a good paper as a starting point. Especially the whale researchers have a lot of expertise in such programs.

Good luck!

Hi Bjarni,
This is a nice project indeed. You must see about small and big creature detection. You may look at the following articles. It may be helpful for your project and may overcome the problem of loosing tags.

Do you got sample images? If there are features that are quite easy to differentiate, then a simple program can do the job. Or if you got very large samples, then a neural network (e.g. convolution NN) could do the job.
