Problems solved by technology

[0003] However, the person recognition based on the lip area has problems such as fewer features and small sample size, which make the recognition accuracy lower; moreover, the captured image has complex background, too strong or too dark light, and the lip area is blocked. Problems such as occlusion and camera angle deviation will also seriously affect the recognition accuracy

Abstract

The embodiment of the invention provides a lip-based person recognition method and device, a computer program product, a computer readable storage medium and electronic equipment. The person recognition method comprises the following steps: performing face detection on a to-be-recognized image, and extracting a lip region image from the to-be-recognized image according to a face detection result;performing feature extraction on the lip region image to obtain lip features; and performing character recognition on the to-be-recognized image according to the lip features. By adopting the technical scheme of the embodiment of the invention, the lip area of the person can be accurately identified by utilizing the better identification capability of the lip characteristics on the mouth of the person, and the accuracy of person identification is further improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of image processing, and in particular, to a lip-based character recognition method, device, computer program product, computer-readable storage medium, and electronic equipment. Background technique [0002] Person identification based on biometric features (such as fingerprints, DNA, face, voice, etc.) has the characteristics of high security and convenience, and has broad application prospects for person identification in security inspection systems such as borders and airports. . Among them, character recognition based on the lip area of ​​the human body is a new type of human body feature recognition method, which can be used to identify the features of the lip area based on images captured by ordinary cameras to achieve character recognition; and can be combined with features such as face and voice Combined to build a multi-modal biometric recognition system to improve recognition accuracy...
