Abstract

A face detection method and a device are provided. The method includes the following steps: acquiring a video stream to be detected; identifying a corresponding dynamic change area from the video stream; and determining face information in the video stream based on the dynamic change area identified. The scheme can improve the speed and accuracy of face detection.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a face detection method and device. Background technique [0002] Face Recognition (Face Recognition), specifically refers to the computer technology that uses the analysis and comparison of facial visual feature information for identity identification. Face recognition technology has a wide range of application prospects, not only for criminal identification, driver's license and passport inspection, immigration management and other biometric identification fields, but also for information security such as identity verification, database management and document management, video conferencing and video surveillance. field. [0003] Face detection is a key link in face recognition. Face detection refers to searching for any given image using a certain strategy to determine whether it contains a face, and if so, return The position, size and pose of the face. [0004] W...
