Abstract

The invention discloses a facial image processing method and device. The method comprises the following steps: detecting a skin color region and a key position in a facial image; constructing a mask corresponding to the facial image according to the skin color region and the key position, wherein the mask is used for exposing regions excluding the key position in the skin color region; and linearly filtering the facial image with the mask as a weight map. In the facial image processing method and device disclosed by the invention, terminal equipment only linearly filters the regions exposed by the mark in the facial image, since only parts to be processed in the skin color region are exposed by the mask, and the images with details, such as five sense organs, and the key positions of the contours of the five sense organs, the facial contour and other lines are not contained, a nonlinear filtering effect can be achieved by means of simple mask and linear filtering.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, in particular to a face image processing method and device. Background technique [0002] With the continuous development and popularization of terminal equipment technologies, more and more users use terminal equipment with cameras to take pictures. In order to beautify the photographs taken, some applications (APPs) that can beautify the photographs have been developed. For example, the filtering process can be performed on the human face to achieve the effect of smoothing and rejuvenating the skin. At present, most of the face filtering methods use nonlinear filtering. This is because nonlinear filtering can not only remove noise but also protect image details and edges under certain conditions, and the filtering effect is good. However, the algorithm complexity of nonlinear filtering is high, which cannot meet the requirement of fast processing. Contents of the invention...
