颜色相似性度量在色差检测中的应用

针对彩色图像缺陷检测中存在的色差问题,在RGB与HSI颜色空间模型的基础上,应用颜色相似性度量的方法来量化一些关键指标,以达到色差识别的目的.实验表明,这种方法符合人眼颜色视觉的相似性判定规律,同时计算简单,易于实现.它不仅避免了复杂的颜色转换过程,而且还能满足颜色视觉特性,因而具有重要的实际意义.

An application of color similarity measurement in color detection

Because of the color image problem in defect detection, a color similarity measurement method to quantify some of the key indicators was adopted in order to achieve the purpose of color identification based on the RGB model and the HSI model. Experiments showed that the approach accorded with the similarity judgment principle of the human visual system. And it was simple to compute and easy to implement. Not only it could avoid the complexity of color conversion, but also it could meet the color visual characteristics. Therefore, it is of practical significance.
