Mouth key point labeling method and device, electronic equipment and storage medium

Abstract

The invention relates to a mouth key point labeling method and apparatus, electronic equipment and a storage medium. The method comprises the steps of obtaining a first face image; determining a firstupper lip area and a first lower lip area on the first face image; determining a target mouth area set according to the first upper lip area and the first lower lip area; when the target mouth area set is empty, determining that outer mouth corner key points comprise a leftmost point and a rightmost point in a union set of the first upper lip area and the first lower lip area; when the target mouth area set is not empty, determining that the outer mouth corner key points comprise a leftmost point and a rightmost point in the target mouth area set; and labeling the mouth key points according to the outer mouth corner key points. According to the method, mouth key points can be automatically labeled, the labeling efficiency is improved, the cost is saved, and when mouth key points marked bythe method provided by the invention are used for training a model, the model training precision can be improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a method, device, electronic equipment and storage medium for labeling key points of the mouth. Background technique [0002] Deep learning has the ability of automatic learning and continuous learning. It has been successfully applied to many fields such as face recognition, image recognition and analysis, speech recognition and natural language processing, and has brought many remarkable effects in these aspects. For the field of facial recognition, the key step is to detect facial parts based on deep learning facial key points (such as eyebrow key points and eye key points). This step is also the premise and breakthrough of automatic facial recognition, expression analysis, 3D facial reconstruction and other face-related problems. [0003] In order to realize facial part detection based on deep learning, a large amount of labeled data of key points of facial pa...
