摘　　要：边缘检测是图象分析和计算机视觉中重要步骤之一。本文在RGB（Red-Green-Blue）彩色空间上引入了一类关于平面结构元素的彩色形态变换，彩色形态变换是数学形态学中灰度形态变换在彩色空间的理论拓展。文中构造了彩色形态滤波器、讨论了彩色形态变换，并提出了基于彩色形态变换的彩色图象边线检测方法。实验结果表明新的彩色图象边缘检测方法是有效而稳健的。Edge detection is the most fondamental and importan step in image and comuter vision.In this Paper, a class ofcolor-scale morphological transforms of color image with nat structuring elemen is presented, which is based on the RGB(Red - Green -Blue)color space, as an exension of gray - scale morphology. Propenies of color - scal mphobocal transform are discussed, and color -scale morphological filters are experimentally analzed. New schemes for edge detechon of color images are developed.Some experimental results show that the new edge detectors are efficient and robust.
