摘　　要：彩色形态变换是数学形态学从灰度图象到彩色图象的推广 .基于 RGB(red- green- blue)彩色坐标系统 ,提出了彩色形态变换的理论 ,并讨论了它们的性质 ,进而建立了彩色形态变换与灰度形态学的联系 .彩色形态变换作为一种数学形态学方法在彩色空间的延拓 ,可有效地应用于彩色图象处理。In this paper, a theory of color scale morphology is proposed, which is an evolution of mathematical morphology from gray scale image to color image. Based on RGB(red green blue) coordinate system, some color scale morphological operators are presented, and their properties are discussed. The relationships between color scale morphology and gray scale morphology are established. Using the basic color scale morphological operations, the other composite color scale morphological transforms, such as color scale opening, closing, iterative morphological filters, color scale morphological gradient and color scale top hat transform etc., can be constructed. Some experimental results are given. As an extension of mathematical morphology to color space, the transformation can be directly and efficiently used to process color image, encode image and extract shape features of objects.
