基于色彩对比最大化的彩色图像边界检测

Color Image Edge Detection Based on Color Contrast Maximization

针对彩色图像,提出一种基于色彩对比度最大化的图像灰度化方法,并在此基础上进行彩色图像的边缘检测,首先将彩色图像的色彩转为符合人眼感知的色彩空间,然后建立目标方程,使灰度化的图像的颜色对比与人眼感知一致,然后对方程求解。最后,使用图像边缘检测算子进行边缘检测,结果证明,比一般彩色图像的边缘检测效果好。

this paper presents a method of transforming a colorful image to greyscale in the edge detection for colorful image. Color information is transformed to a space of suit to human vision system first, and a objective function on closeness between pixels distance in gray image and distance in new color space is built, then the function is solved. Finally, edge detection algorithms used in gray image are taken to the target gray image. Edges detected are illustrated better results than previous methods.
