摘要
提出一种基于Lab颜色空间的彩色等差线提取新技术,即针对白光光源的彩色等差线条纹图特点,将图像从RGB颜色空间转换到Lab颜色空间a通道,实现对彩色等差线条纹的精确提取.
A new technique used for isochromatic extraction is proposed on the basis of Lab color space. According to the isochromatic color character of a photoelastic model in circular polariscope with white light, fetch isochromatic skeleton lines accurately by transforming the RGB color space into channel a of the Lab color space.
