In order to segment miners\' faces in dim-lightening laneway monitor images,the statistic feature of miners\' face color is analyzed separately in tri-component of YCbCr color model.

The License Plate Location: a method of color License Plate Location which based on YCbCr color space and projection method, this method extractive the Cb component of YCbCr color space.

; and uses JPEG image compression coding and HVS as Basics, studys some domain-based DCT image watermarking algorithms; then use of spread-spectrum technology, presents a block-based DCT dual-color image watermarking algorithm which is described as follows:First of all, the color watermark image and the original carrier image are converted from the RGB color space to the YCbCr color space.

In this paper,the background is firstly modeled using adaptive Gaussian mixture models in YCbCr color space,and the foreground regions including moving objects and cast shadow are extracted from current frame by comparing the each pixel with Gaussian model.

Review on application of color model in monitoring nitrogen status of vegetables;

An object extraction method based on HSI color model;

Adaptive background updating based on dynamic information window was used to solve the problem of complicated background,and a novel color model was used to dispel motion shadow.

An object extraction method based on the HSV color model was proposed,which could be used for testing the blended ratio of cashmere/wool yarns.

By this concept and together with HSV color model, we can successfully segment the face image.

A support vector machine(SVM) object extraction method was proposed based on the HSV color model,which could be used for testing the blend ratio of cashmere/wool yarns.
