摘　　要：材料腐蚀特征颜色的人工评定无法解决颜色量化问题,在RGB空间获取材料腐蚀特征图像信息,通过HSV颜色空间对该腐蚀特征区域的颜色值进行相应量化处理,获得一维特征矢量直方图。由于材料腐蚀特征区域颜色并非单一、均匀分布,材料腐蚀特征区域中的颜色具有敏感点及颜色信息偏态分布,其用平均值方法无法进行有效处理,所以使用区域分块、累计百分比方式对区域中的颜色进行权重处理,从而实现在HSV空间下对材料腐蚀特征区域颜色量化处理,使得特征区域颜色值符合人工评定颜色的需要。Artificial assessment of the color on the material corrosion feature could not solve the problem of color quantization. In order to get one-dimensional feature vector histogram, the regional color of the material corrosion feature is quantified for value processing in HSV color space. Due to the regional color of the material corrosion feature is not a single, uniform distribution. At the same time,the regional color of the material corrosion feature is sensitive and color information Skewed distribution,generally will not be able to effectively deal with average method. So the regional block and the cumulative percentage method are used to weight, which realize the color quantizing of corrosion feature in HSV colour space and make the colour conform to the need of artificial color.
