Method and device for acquiring human face skin color region from image

Abstract

The invention discloses a method and device for acquiring a human face skin color region from an image, wherein the method and the device can be used for filtering an image to be detected simply and rapidly and enhancing image recognition accuracy rate and an image filtering effect. The method for acquiring the human face skin color region from the image, provided by the embodiment of the invention, comprises the steps of: performing region segmentation on the image to obtain a skin color region of the image to be detected; recognizing a human face region in the image to be detected; acquiring the human face skin color region according to the human face region and the skin color region in the image to be detected; and judging whether a specific value of the human face skin color region to the skin color region is more than a preset proportion threshold or not, if so, accepting the image to be detected, and if not, rejecting the image to be detected.

Description

technical field [0001] The invention relates to the technical field of image graphics processing, in particular to a method and a device for acquiring a human face skin color area in an image. Background technique [0002] With the advancement of image graphics technology, the filtering technology of yellow pictures has also been greatly developed. Initially, people first searched for people on yellow pictures, then looked at the actions after finding the people, and pre-defined some parts of people such as hands, feet, head, shoulders, etc., and then analyzed the actions to identify them. This technology often treats people and sculptures in group photos as pornographic pictures, and coupled with the inability to recognize faces, this method was quickly eliminated. [0003] The current yellow image filtering technology mainly relies on skin color to distinguish, but some allowed images have a large area of ​​skin color, such as large head portrait photos, face photos, etc....

This technology often regards the people and sculptures in the group photo as pornographic pictures, coupled with the inability to recognize faces, this method is quickly eliminated

[0003] The current yellow image filtering technology mainly relies on skin color to distinguish, but some allowed images have a large area of ​​skin color, such as large head portrait photos, face photos, etc., which are easily misjudged as yellow images and filtered out, resulting in The accuracy of image recognition is low, and the effect of image filtering is poor
