彩色图像处理中照明颜色的过滤方法

Filtering method to illustrate color in colorful image processing

在双色反射模型的基础上通过有限函数的线性组合来表示照明与反射.利用对图像颜色分布的主成分分析得到颜色分布的主平面,并在主平面内通过Hough变换检测出照明颜色和物体颜色所对应的直线段,在此基础上通过简单运算从图像上过滤照明颜色的影响.实验结果表明了该方法的有效性.

On the basis of the double-color reflection, the illustration and reflection is noted for the linear combination of the finite function. The main plane of the color distribution can be gotten by analysing the main components of color distribution. And the direct segment that equals the illustration color and the object color can be detected by the Hough transform method. On the basis of the above, the effect of illustration color can be filtered by some sample operations.
