Abstract: Fish image recognition and prediction is a challenging task. This Paper gives an idea about recognition of fish image using correlation coefficient and then Histogram of oriented Gradient (HOG).Finally the fish images are classified based on their features using Support Vector Machine (SVM).This paper aims to detect which species of fish appears on a fishing boat, based on images captured from boat cameras of various angles and this can be used to prevent fishing of endangered fishes.
