Abstract

The invention discloses a face image processing method which comprises the following steps of performing face detection on a current image frame and generating a face reference area; performing key point detection on the face reference area, and identifying face key points; dividing an initial face skin area in the image frame from the face reference area according to the face key points; calculating an initial hair area in the image frame according to the face reference area and prior knowledge; performing probability distribution estimation on characteristic vectors of pixel points in the skin area and the hair area by means of a Gaussian mixture model; performing image dividing on the image frame according to a probability distribution estimation result, and obtaining a head area of the image frame; and amplifying the head area by means of an interpolation algorithm, thereby obtaining a processed image frame. The invention further discloses a corresponding face image processing device.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a face image processing method and device. Background technique [0002] As the main carrier of information, image and video data have attracted more and more attention because of their visual intuition and vividness of expression. At present, users are not only satisfied with obtaining higher-quality images and videos (since videos can be regarded as a combination of multiple frames of images, images will be used instead of images and videos in the following discussion), but also put forward suggestions for the interestingness and aesthetics of images. higher requirement. [0003] In the past, professional and technical personnel were required to modify and process images, and it was difficult for ordinary users to adjust image content according to their preferences. Now, it has become a common method to modify the image content through the set image processing algori...
