基于最佳漫反射像素的汽车表面高光检测

汽车表面常常反射出表征光源颜色的高光,高光的颜色严重影响了汽车的真实颜色.因此在识别汽车颜色之前需要将汽车表而的高光像素检测出来,以提高颜色识别的准确率.结合原图像和对应的无高光图像提出了最佳漫反射像素的概念,并以最佳漫反射像素为基础提出了一种检测单张彩色图像中汽车表面高光的算法.算法简单、容易实现,其理论基础是二分光反射模型.实验结果表明算法有效、运算速度快,可以满足汽车颜色识别系统准确性和实时性的要求.

Highlight Detection of Surfaces of Vehicles Based on Best Diffuse Reflection Pixel

The colors of highlight reflected from surfaces of vehicles seriously affect vehicles' true colors.In order to improve the accuracy of color recognition,highlight pixels on surfaces of vehicles need to be detected before recognizing vehicles' colors.In this paper,a new conception named best diffuse reflection pixel is put forward by using the input image and corresponding specular-free image,based on which an algorithm for detecting highlight pixels within a single color real image is proposed.This algorith...
