Image segmentation method and device and electronic equipment

The invention discloses an image segmentation method and device and electronic equipment, and belongs to the field of image processing. The image segmentation method provided by the invention comprises the following steps: performing multiple iterative calculations on the position of each individual in a group by adopting a group intelligent optimization algorithm, and determining to obtain a global optimal solution of the group; wherein the fitness function of the swarm intelligent optimization algorithm is used for evaluating the segmentation quality of the target image, and entropy parameter values indicated by the positions of the individuals are different; determining an entropy parameter value indicated by the globally optimal solution as a target entropy parameter value; determining a target threshold value corresponding to the target entropy parameter value according to the target entropy parameter value; and segmenting the target image according to the target threshold. The method is used for image s
