Problems solved by technology

[0002] In the existing technology, there are many algorithms for eliminating image light noise, but there are few algorithms for locating light noise. A big difficulty is that it is difficult to determine the distance between overexposure (high light area) and white object (white light area). The difference, coupled with the complexity of the natural image, makes it more difficult to locate the light noise area; in the prior art, the processing method of directly performing highlight removal on the image to be processed is easy to mishandle the white light area, making it not belong to skin oily The area is also removed, which makes the image distorted and the user experience is not good

Abstract

The invention discloses an automatic gloss removing method and system for a face area and a shooting terminal. The method comprises that the skin area of an image to be processed is obtained; the brightness of the face skin area is analyzed to obtain a highlight area; edge detection is carried out on the highlight area, and according to a result of edge detection, areas of white objects are rejected to obtain a glossy area; and highlight is removed from the glossy area to obtain a recovery image. Thus, gloss can be identified accurately and eliminated effectively, and the processing effect is better.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method for automatically removing oiliness in a human face area and a system and a shooting terminal for applying the method. Background technique [0002] In the existing technology, there are many algorithms for eliminating image light noise, but there are few algorithms for locating light noise. A big difficulty is that it is difficult to determine the distance between overexposure (high light area) and white object (white light area). The difference, coupled with the complexity of the natural image, makes it more difficult to locate the light noise area; in the prior art, the processing method of directly performing highlight removal on the image to be processed is easy to mishandle the white light area, making it not belong to skin oily The area is also removed, which makes the image distorted and the user experience is not good.
