Abstract

The present invention provides a face detection method, device, equipment, and computer-readable medium, and relates to the field of image recognition technology. The method includes: acquiring the actual position information of a plurality of face images detected in the previous k times of face detection, k It is a positive integer greater than or equal to 2; the predicted position information of the face image at the k+1th detection is predicted according to the actual position information detected in the previous k times; the predicted position information meets the preset conditions according to the human face The preset threshold range corresponding to the number of images determines the target frequency, and then adjusts the detection frequency to the target frequency. The embodiment of the present invention can automatically adjust the frequency of face detection according to the predicted position information of the face image in the frame image, saving the calculation of the system Resources, the technical effect of reducing energy consumption in face detection of video streams.

Description

technical field [0001] The present invention relates to the technical field of image recognition, in particular to a face detection method, device, equipment and computer readable medium. Background technique [0002] Face Detection is the first step in analyzing and processing face images. It is used to detect and locate faces in images, and return high-precision face frame coordinates. The traditional detection algorithm is to scan a picture and determine whether a picture area is a face one by one. [0003] However, since each second of video is composed of many frames, the frame numbers of general cameras are divided into PAL system (Pal system) and N system (color TV broadcasting standard), which are 25 frames per second and 30 frames per second respectively. Frames, the current high-speed cameras can reach more than 120 frames per second. In this way, the use of the current face detection algorithm is often accompanied by problems such as large amount of calculation ...
