Aiming to reduce the computational complexities and accelerate the search speed, the artificial fish algorithm(AF- SA) was introduced to more rapid optimization of maximum entropy multiple threshold, a novel maximum entropy multiple threshold strawberry image segmentation method (AFSAMEMT) based on AFSA was proposed. Firstly, the R component gray images of RGB color images and their gray image information were extracted, and then the multiple threshold integer coding was designed and the maximum entropy was converted to the coding correspon...
