Abstract

The invention discloses a face detection method and device based on a video image. The face detection method includes the following steps: copying two copies of an input original image, performing buffer processing on one original image to obtain a first image, and the other The original image is compressed according to the preset compression factor to obtain the second image; the first feature detection is performed on the face features of the second image to obtain the detection area of ​​the second image; according to the compression factor in the first image, etc. Proportionally find out the local area corresponding to the detection area, and perform a second feature detection on the face features of the local area to obtain the face detection area of ​​the first image; the face detection area of ​​the first image and the second image The detected areas are merged to obtain face metadata; and the face detection result and face metadata are output. The technical solution of the present invention can improve the recognition efficiency of face detection, reduce processing difficulty, and take into account both efficiency and effect.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a face detection method and system based on video images. Background technique [0002] At present, with the continuous development of face detection technology, various excellent face detection algorithms are emerging, and the effect is close to or even surpasses the recognition ability of human eyes in some cases. However, the complexity of the method is getting higher and higher. The simple method has high efficiency, but the effect is poor, and the complex method is effective, but the efficiency is low. Efficiency and effect become a contradiction. Finding a face detection method with good effect and high efficiency has become a hot spot of competition. [0003] In view of this, it is necessary to propose further improvements to the current face detection technology to take into account the efficiency and effect of image processing.
