Embodiment Construction

[0023] Below in conjunction with embodiment, the present invention is described in further detail.

[0024] The skin color detection method in the color image of an embodiment of the present invention, it comprises following concrete steps:

[0025] (1) Color space conversion. Given a color image to be inspected, convert it from the original color space to a color space with good aggregation of skin color and good discrimination between skin color and non-skin color.

[0026] In order to be different from the original color space of the image and convenient for expression, the converted color space is called a classified color space in this embodiment. In this step, the classification color space can be YCrCb, YUV, Lab, HSV, HIS, normalized RGB, etc., or it can be other colors with good aggregation of skin color and good discrimination between skin color and non-skin color under the same lighting conditions. space.

[0027] In this embodiment, the color in the preferred cla...

Abstract

The invention discloses a method for detecting a skin color in an image. The method comprises the steps of (1), converting a to-be-detected color image from an original color space to a classified color space of the skin color; (2), detecting a human face, eliminating non-skin parts on the human face, and obtaining a human face skin area; (3) on the color image after color space conversion, acquiring the color of pixels in the human face skin area defined in the step (2) as a skin color sample; (4), establishing a skin color classifier according to the acquired skin color sample; and (5), classifying the whole image in a pixel-by-pixel manner by means of the skin color classifier established in the step (4), marking the pixel points which are classified to the skin color with white color on a skin color detection result image, and otherwise, marking with black color, thereby obtaining the skin color detection result image. The method of the invention can accurately detect different skin colors in the color image which is photographed by different kinds of imaging equipment on various illumination conditions.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method for detecting skin color in an image. Background technique [0002] In color images, since skin color information is not affected by human body posture, facial expressions, etc., it is relatively stable, and because skin color is significantly different from the color of most background objects, skin color detection technology is very important in detection, gesture analysis, etc. , object tracking and image retrieval are widely used. The goal of human skin color detection is to automatically locate the naked skin area of ​​the human body from the image, for example, to detect the human face, hands and other areas from the image. [0003] In the prior art, the process of detecting the skin color area is usually implemented based on methods such as single Gaussian model method, mixed Gaussian model method, ellipse skin color model method and the like....
