Embodiment Construction

[0034] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0035] A method for segmenting skin color regions in an image provided by Embodiment 1 of the present invention, see figure 1 , including:

[0036] 11: Obtain the HSV data of each pixel in the image to be detected;

[0037] The above-mentioned HSV data is the data of each pixel in the image to be detected in Hue, Saturation, Value (Hue, Saturation, Value) color space.

[0038] 12: Clustering each pixel according to the HSV data to obtain a clustering result image;

[0039] 13: Based on ...

Abstract

The invention discloses a cutting method and a device for a skin color area in an image. The skin color area can be obtained quickly and effectively and the computation speed and the image cutting efficiency are improved. The cutting method for the skin color area in the image, which is provided by the embodiment of the invention, comprises the following steps: hue, saturation and value (HSV) data of each pixel point in the image to be detected are obtained; the pixel points are clustered according to the HSV data so that a cluster result image is obtained; the threadhold value range of a hue H is chosen based on the statistical result; and according to the H component of each pixel point in the cluster result image and the threadhold value range of the H, area cutting is carried out so that the skin color area of the image to be detected is obtained.

Description

technical field [0001] The invention relates to the technical field of image segmentation, in particular to a method and device for segmenting a skin color area in an image. Background technique [0002] Image segmentation has always been a basic and important issue in the field of graphics and image processing. Many subsequent operations are based on the segmentation results. Whether the segmentation effect is good or bad will directly affect the final image processing results and even the performance of the overall system. , if the segmentation of the road image is not accurate when the robot car is driving, it will directly affect the running performance. [0003] Skin color segmentation technology is one of the hotspots in current image segmentation research. It has important applications in face recognition, expression recognition, human hand tracking, human-computer interaction, moving human target tracking, and pornographic image filtering. At present, the proliferat...
