Abstract

The embodiment of the invention provides a front face detection method, electronic equipment and a medium. The method comprises the following steps: obtaining a face image in a to-be-detected image as a first face image, and obtaining a face image detected from a previous to-be-detected image of the to-be-detected image as a second face image; matching the first face image with the second face image; determining an identity label of an object to which the matched first face image and second face image belong; removing images of which the image sizes do not meet a preset front face size condition in the face images corresponding to each identity label, and taking the remaining face images as primary processing images corresponding to the identity label; and based on the position information of the face image in the to-be-detected image, rejecting a non-front-face image in each primary processing image corresponding to each identity label, and taking the remaining primary processing images as front-face images of the object corresponding to the identity label. By adopting the method, the accuracy of front face detection is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a front face detection method, electronic equipment and media. Background technique [0002] With the continuous development of image processing technology, frontal face detection technology is also widely used in our daily life. For example, face detection can be performed on the video images of various entrances, and then the people passing through the entrance can be determined; another example, pedestrians who run red lights can be determined through frontal detection technology. [0003] At present, the method of key positioning is usually used for frontal face detection, that is, to locate the key points of the face, and then perform affine transformation on the key points to realize the frontal face detection. However, since the positions of the located facial key points are not necessarily accurate, the accuracy of frontal face detection is low. Conten...
