Problems solved by technology

[0004] However, in the above method, the default is that the skin color area is a rectangular area in the chroma and saturation space, and this method is not very adaptable to complex, non-rectangular skin color distributions.

Embodiment Construction

[0089] In order to make the objectives, technical solutions, and advantages of the present disclosure clearer, the following further describes the present disclosure in detail with reference to the embodiments and the drawings. Here, the exemplary embodiments of the present disclosure and the description thereof are used to explain the present disclosure, but are not intended to limit the present disclosure.

[0090] The embodiments of the present disclosure provide a skin color detection method and device. The present disclosure will be described in detail below with reference to the accompanying drawings.

[0091] In one embodiment, such as figure 1 As shown, the skin color detection method includes:

[0092] Step S101: Convert the image to be detected into an image in the color space.

[0093] After obtaining the image to be inspected, convert the image to be inspected to the color space (YUV space) to obtain the brightness channel Y(x,y) and UV channel UV(x,y), x∈[0,m],y∈ [0,n], ...

Abstract

The invention relates to a skin color detection method and a skin color detection device. The skin color detection method comprises the following steps: converting a to-be-detected image into an image in a color space; acquiring the skin color sample of the to-be-detected image in the color space; and adopting a pre-constructed skin color probability model to detect the skin color sample so as to obtain the skin color probability distribution of the to-be-detected image, wherein the skin color probability model is a model which is obtained through training with the use of a known skin color sample and is used for determining the skin color probability. The method can be applied to non-rectangular complex skin color distribution.

Description

Technical field [0001] The present disclosure relates to the field of image processing technology, in particular to the skin color recognition of images, and specifically to a skin color detection method and device. Background technique [0002] The skin color detection of color images is a method for automatically identifying the skin area in the image. It has a wide range of application scenarios. It is an important part of applications such as color correction, sensitive information monitoring, and a series of target detection and recognition (face detection, gesture recognition). [0003] Experiments show that after removing the influence of brightness from the image, the skin color of people of different ages, genders, and races has obvious clustering in the chromaticity space, and the skin color is concentrated in a small range in the entire chromaticity space. In the related art, taking face skin color detection as an example, first use the information of the face detection,...
