基于HSI空间改进的彩色图像边缘检测方法
Improved Color Image Edge Detection Method Based on HSI Color Space
摘要
Abstract
In order to extract more accurate color image edge information,an improved color edge detection method is proposed by HSI color space within reflecting human vision feature.According to the G-L definition of fractional differenti-al,a 5×5 mask operator is constructed,which is used to extract edge information of saturation and intensity.The hue edge information is extracted by a new color measurement method.Afterwards,taking advantage of data fusion technique,the color image information is combined the edge information of hue,saturation and intensity.Finally,the non-maxima suppres-sion and threshold selection are employed to extract edge points.Experimental results demonstrate that the proposed method could apply information of hue,saturation and intensity,which extracts more complete of color image edge information.关键词
