【摘要】 文中给出了一种彩色边缘的定义,阐述了彩色边缘的特点,提出了一种在HSI彩色空间使用的基于彩色图像方向区域距离测度的彩色边缘检测新方法。该方法定义的方向区域距离测度充分考虑了边缘的方向性和滤波尺度对边缘检测的影响。通过选择不同的权重,可分别求取色调边缘,色度边缘,饱和度边缘,亮度边缘以及它们的组合边缘,能满足不同应用的需要。实验表明,该方法能提取更多的彩色边缘信息并具有很好的抗噪性能。更多还原

【Abstract】 This paper gives a definition of color edge, expounds characteristics of color edge and proposes a new color edge detection approach based on the direction region distance measure(DRDM) for color images using in the HSI color space .The defined DRDM focuses on the direction property of edge and the filter scale′s effect on edge detection,Hue edge images, chromaticity edge images,saturation edge images,luminance edge images as well as combinatorial edge images which combine the hue, saturation and luminance edges can be got respectively by their respective weight, so it can satisfy the needs of different applications. The experiments carried out show that more color edge information is observed and more noise is suppressed by the proposed method in this paper .更多还原
