Abstract

The invention provides a face detection method and device. The method includes: preprocessing the current frame to obtain a grayscale image of the current frame; using a human figure classifier to detect a human figure on the grayscale image of the current frame; judging whether a humanoid area is detected in the grayscale image of the current frame, when When a human-shaped region is detected, select the human-shaped region as the region of interest for face detection, otherwise find the region of interest for the face detection of the current frame; use the face classifier to carry out face detection for the region of interest; according to The coincidence degree stores the face detection results in an orderly manner. The invention can improve the detection efficiency of human face detection.

Description

technical field [0001] The invention relates to the technical field of pattern recognition, in particular to a face detection method and device. Background technique [0002] Face recognition refers to computer technology that uses the analysis and comparison of facial visual feature information for identification. It is the focus of artificial intelligence and pattern recognition, and is widely used in national security, military security, identification, banking and customs monitoring, Access control system, video conferencing and other fields. [0003] Face detection is a key link in face recognition. Face detection means that for any given image, a certain strategy is used to search it to determine whether it contains a face, and if so, return the position of the face , size and pose. [0004] The commonly used face detection method at this stage traverses the entire image and uses a classifier to detect the entire image, which is inefficient and prone to false detecti...
