Matlab程序,实现了一种新的色彩白平衡算法。 针对物体在有色光源照射下呈现偏色的现象,提出一种改进的LoG边缘自动白平衡算法。该算法在YCbCr空间的Cb和Cr分量上同时利用LoG算子提取边缘,利用LoG边缘具有零交叉特性直接得到边缘两侧的像素。为了避免占主导的彩色纹理造成干扰,利用白色区域的偏色信息进行边缘抑制。利用得到彩色边缘对原图的偏色进行有效的估计,最后计算三颜色通道的增益并进行白平衡。对大量图片进行了实验,结果表明该算法对不同色光照射下的图像均能很好地进行白平衡,同时与多种白平衡算法的对比实验表明该算法适应面广,性能良好。

Add Gaussian white noise (mean=0 and variance=0.05 ) to the image using
imnoise command. Now use fftshift command to put all zero frequencies in the
middle. Low-pass filter this function by applying a mask saving only the central
Fourier coefficients. Set the mask width to 255 and create the filtered image.
