) automatically with images taken in the wild. ...
Although big variation in illumination, poses of the trouts, and resolution we validated that just using a small patch taken from the head of the trout, which can minimize the variations, it's possible ...
Thus, the goal of this paper is to propose an automatic image-based method for individual recognition of brown trouts (Salmo trutta) in the wild. ...
