The method comprises the following steps that: 1) a face detection model is established, the model adopts an RFCN network structure, wherein the RFCN network structure comprises a feature fusion-based feature extraction layer; 2) a sample set is obtained; 3) the face detection model established in step 1) is trained; and 4) the trained face detection model is adopted to perform face detection on a picture to be detected. Compared with the prior art, the method of the present invention has the advantages of high accuracy, high recall ratio, good adaptability for complex scenes, and the like.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to a face detection method based on a convolutional neural network. Background technique [0002] Face detection is a research topic involving computer vision, pattern recognition, artificial intelligence and other fields. Because of its wide application value in commercial, medical and military fields, it has always been a hot research topic. However, in real-world scenarios, faces in complex images are often severely occluded, which poses a huge challenge to face detection, so it is still a research to propose a face detection method that can adapt to severe occlusions. difficulty. [0003] Literature "Object Detection via Region-based Fully Convolutional Networks" (Dai, J., Li, Y., He, K., Sun, J.: R-FCN:.In: 30th Conference on Neural Information Processing Systems, pp.379 -387.Barcelona) discloses a target detection method based on regional fully convolutional neural ...
