Abstract

An image segmentation method and device are disclosed. The method comprises the following steps of: acquiring an image to be processed; inputting the image to be processed into a skin segmentation network to obtain a probability map of the image to be processed; a obtaining segmentation map of the image to be processed by segmenting according to the probability map, wherein the segmentation map comprises at least one of a face region, a torso region and a background region. The image segmentation network is used to process the image to be processed, the probability map of the image to be processed is automatically and quickly obtained, and the face region, torso region and background region of the image to be processed are accurately divided based on the probability map, and the corresponding segmentation map is obtained. On the other hand, based on the probability map, the dispersion degree and area criterion of skin blocks, the final confidence level can be obtained to judge the quality of skin segmentation of the image to be processed.

Description

technical field [0001] The present application relates to the field of image processing, in particular to an image segmentation method and device. Background technique [0002] The traditional image skin segmentation method is mainly based on the skin color of the human body. However, the skin color of the human body varies greatly in different scenes. Dark and if the light is not enough, the skin will be very dark. In addition, the skin color of different races is completely different. For example, the corresponding skin colors of Chinese, Indians, Americans, and Africans are yellow, brown, white, and black respectively. Therefore, the robustness of the segmentation effect of the traditional method is poor, and it cannot distinguish the skin regions of different people in the image, and the effect in complex scenes is even less ideal. Contents of the invention [0003] The present application provides an image segmentation method and device, so as to realize the segment...
