Embodiment Construction

[0062] see figure 1 As shown, a content-based human upper body sensitive image recognition method of the present invention includes:

[0063] First of all, the system initialization process and threshold setting are carried out. The system sets various threshold initial values ​​according to known historical data; the various thresholds used by the system are preset by the user, and the global skin color model is also established by the user here; the threshold It is obtained based on experience, which includes skin color area threshold, YCrCb size threshold, etc.; historical data refers to some empirical data in this industry; such as figure 1 shown in box 101 in

[0064] Steps to input an image; such as figure 1 shown in box 102 in

[0065] The step of performing face recognition processing on the input image; this step is to use artificial neural network for face recognition; first, face recognition training is performed, using 2,000 face images and more than 20,000 non-...

Abstract

The invention discloses a content-based human body upper part sensitive image identification method and a content-based human body upper part sensitive image identification device. The method comprises the following steps of: performing human face identification on static images and removing images which do not contain human face information; identifying a texture image by using neural network identification and finding out related sensitive information positions; generating a human body skin color model of the image by using the color distribution information in a detected human face area and the default skin color information; extracting the human body skin area from the image according to the established human body skin color model; and if the sensitive information image and the human face information image are consistent with a human body upper part shape model, and the skin ratio of the sensitive information image exceeds a threshold, determining the image as the sensitive image. In the invention, human face identification, human body upper part identification and sensitive image identification are used in combination to differentiate sexy photo images from pornographic sensitive images, so that the error report rate of the sexy photo images is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of sensitive image filtering, in particular to a content-based sensitive image recognition method for the upper body of a human body and a device thereof. Background technique [0002] With the rapid development of modern Internet technology, network communication channels are spread all over the world. While the Internet brings convenience to people, it also brings some security risks. For example, the illegal dissemination of pornographic images on the Internet is one of them. Due to the illegal dissemination of pornographic images on the Internet, it has brought a series of social problems and Legal issues, especially for young people, have caused great harm and thus attracted the attention of the public and the industry. Some software for filtering pornographic images has also emerged as the times require, and these software aim at removing pornographic images by identifying them. [0003] In the exist...
