Abstract

The invention discloses a face detection method, device and equipment and a computer readable storage medium, and the method comprises the steps: obtaining a face region of an image through a full convolutional neural network according to the received image; performing selective search on the face region to obtain deep face frame features; carrying out binarization processing on the deep human face frame features, and positioning human face candidate regions of the frame-selected human face contour from all human face regions; obtaining a plurality of face candidate boxes with different sizesthrough a pre-constructed image pyramid model according to the face candidate area; according to the face candidate frame, obtaining the face detection result through the cascade neural network. Missing detection of small faces can be effectively avoided through the method, the position of the face frame is calculated in a layer-by-layer fine mode through the cascade neural network, and the face detection accuracy is improved.

Description

technical field [0001] The present invention relates to the field of computer image processing, in particular to a face method, device, equipment and computer-readable storage medium. Background technique [0002] With the development of computer technology, especially pattern recognition technology, face detection appears in people's field of vision as a technical direction. Face detection technology can be used as the basic work of multiple application projects in the field of image processing and video analysis, such as face recognition, face image retrieval, and driver fatigue detection. However, when there are large and small faces with inconsistent sizes in an image, due to the deviation of the face frame of the traditional deep feature in the original image mapping face frame, the detection of small faces is inaccurate. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a face detection method, device...
