Face image detection method and device

Abstract

The invention belongs to the technical field of face detection and relates to a face image detection method and device. The method comprises the following steps of: 1, obtaining a to-be-detected imagecontaining a face image; 2, performing feature information extraction on the to-be-detected image containing the face image through a classification network; 3, transmitting feature information to adetection network, and locating face region output. A Condensenet containing residual units is used as a feature extraction network; the Condensenet is connected by using an SE module; useful featureinformation is enhanced; the specific YOLO layer of YOLOv3 is used as a detection layer to detect feature information of a large scale, a medium scale and a small scale; the Condensenet can connect the feature maps of different convolution blocks; adjacent convolution blocks are connected through a pooling layer in a proper size, so that the feature information is received more completely; the problem of the gradient disappearance of a certain deep convolution network can be solved; and detection precision is improved to a greater extent.

Description

technical field [0001] The invention belongs to the technical field of face detection, in particular to a method and device for detecting a face image. Background technique [0002] At present, e-commerce is developing rapidly, and face recognition has become the most potential means of biometric authentication. This application background requires automatic face recognition systems to have a certain ability to recognize general images. Face detection began to receive the attention of researchers as an independent subject. According to statistics, nearly 80% of the traffic transmitted on the network is multimedia content, and multimedia applications have become an important content of Internet applications. Streaming Media (Streaming Media) refers to the multimedia application that video, sound and data are sequentially transmitted from the source to the destination in a continuous stream through the real-time transmission protocol.
