Abstract

The invention relates to an image segmentation method and device, electronic equipment and a storage medium, and belongs to the field of computer vision, and the method comprises the steps: obtaininga to-be-segmented image, and carrying out the face detection and face key point detection of the to-be-segmented image; based on the obtained first face detection result and the first face key point detection result, cutting out a first face area in the to-be-segmented image; based on the image segmentation model, performing hair segmentation on the first face region, the image segmentation modelbeing obtained based on a sample image, a labeling mask map and a hair probability distribution map through training, the labeling mask map providing a hair region in the sample image, and the hair probability distribution map providing hair segmentation probability distribution of the sample image. Hair segmentation can be finely carried out based on the trained image segmentation model, the segmentation efficiency can be ensured, meanwhile, the segmentation precision is improved, and the hair segmentation mode is good in effect.

Description

technical field [0001] The present disclosure relates to the field of computer vision, and in particular to an image segmentation method, device, electronic equipment and storage medium. Background technique [0002] Hair is an important local feature that distinguishes different faces and plays a vital role in a person's overall image. Based on this, hair-related applications such as hair segmentation have received increasing attention in recent years. Among them, the hair segmentation technology is a technology for automatically segmenting hair regions, which can be applied in scenarios such as hairstyle color change, hair accessories try-on, hairstyle recognition, gender and age estimation, etc. [0003] As we all know, when the hair segmentation is performed on an image, if the segmentation accuracy can be improved while ensuring the segmentation efficiency, the better the hair segmentation effect will be, the more it can meet the application requirements. Therefore, h...
