Embodiment Construction

[0052] In the present invention, the skin texture detection system at least includes an image division unit, a feature extraction unit, a screening unit and a merging unit. The system extracts the microstructural features of the skin window, and performs multi-level feature selection according to the microstructural features, thereby Screen out the candidate skin windows that meet the detection conditions, and then merge them. Therefore, the false detection rate is reduced, and the detection efficiency is improved.

[0053] figure 1The structure of the system for detecting skin texture on images in the first embodiment of the present invention is shown, and the system includes an image division unit 10 , a feature extraction unit 20 , a screening unit 30 and a combination unit 40 . It should be noted that the connection relationship between the various devices in all the diagrams of the present invention is to clearly illustrate the needs of their information interaction and ...

Abstract

The invention relates to the communication and image processing field, and provides a method and a system which are used for conducting the skin-texture detection on an image. The method comprises the following steps: (A) an initial skin area is determined in an input image and is divided into a plurality of skin windows; (B) micro structural features of the skin windows are obtain through extraction; (C) the multi-level feature selection is performed on the skin windows according to the micro structural features, and candidate skin windows corresponding with detection conditions are screened out; (D) the adjacent candidate skin windows are merged, and the attribute information of all skin-textures containing in the image is determined. The system comprises an image dividing unit, a feature extraction unit, a screening unit and a merging unit. The method and the system are distinguished from the prior art by the micro structural feature extraction of the skin windows and conduct multi-level feature selection according to the micro structural features, thereby merging after the candidate skin windows corresponding with detection conditions are screened out. Therefore, the false detecting rate is reduced, and the detection efficiency is increased.

Description

technical field [0001] The invention relates to the fields of communication and image processing, and more specifically, to a method and system for detecting skin texture on images. Background technique [0002] With the rapid development of computer hardware and software and Internet technology, people can not only obtain a large amount of information from various multimedia materials, such as text, pictures, video, audio, etc. However, it will also cause people to be harassed by unhealthy pictures and videos such as pornography and violence. The proliferation of pornography on the Internet has become a relatively serious social problem. Therefore, it is very necessary to detect sensitive images, so that sensitive The image is filtered out. Sensitive images may have large differences in content, but the common point is that they all contain a large number of exposed skin areas, so the sensitive image detection problem is attributed to the skin detection problem. [0003] ...
