提出了一种在RGB颜色空间中颜色距离定义的方式,并根据颜色距离,用Roberts梯度算子得到颜色距离直方图,确定图像边缘信息的阈值。通过Roberts算子,使用此阈值得到图像的边缘信息。这种方式,充分考虑了图像中的颜色信息,与灰度图的处理方式相比,减少了计算量,提高了具有相似亮度的不同颜色之间边缘信息的提取成功率。

A color distance in RGB space is defined.According to the color distance the histogram is gotten by the Roberts gradient operator.And with the histogram is defined,the threshold of image edge information is gotten.Further through the Roberts operator,uses this threshold to get the edges of the image.In this way,fully consider the colors in the image information,compared with the gray-level approach,reduces the amount of calculation and increases the success rate of extraction of edge information which has similar brightness between different colors.
