Embodiment Construction
[0028] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0029] A face detection method under unrestricted conditions of the present invention, the network model obtained after training can realize end-to-end face detection; when the video frame enters the network, the probability of the detection result and the position information of the target are output; The maximum value suppression and probability screening can get the specific coordinates of the face.
[0030] A face detection method under unrestricted conditions, comprising the steps of:
[0031] S1) Image preprocessing
[0032] For public data sets collected from the Internet, horizontal flip is used for data enhancement;
[0033] For the self-collected 1080p video data, extract video frames that can be used for face detection, manually or machine-label each frame, and scale down each face that appears in the video frame, respectively redu...
