- 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

边缘提取
- 边缘提取:边缘检测的基本思想首先是利用边缘增强算子,突出图像中的局部边缘,然后定义象素的“边缘强度”,通过设置阈值的方法提取边缘点集。由于噪声和模糊的存在,监测到的边界可能会变宽或在某点处发生间断。因此,边界检测包括两个基本内容: (1)用边缘算子提取出反映灰度变化的边缘点集。 (2)在边缘点集合中剔除某些边界点或填补边界间断点,并将这些边缘连接成完整的线。(Edge extraction: the basic idea of edge detection is to use edge en
