摘　　要：对RGB颜色空间进行剖分,根据剖分的结果,定义了RGB空间中一点的彩色信息量,通过像素点在相关邻域上的信息量的计算,确定该像素点是否为彩色图像的边缘点。这种边缘检测方法,在一定程度上合理地考虑了个各颜色分量的相关性,将向量空间的计算以自然的方式转换成了标量的计算,在思想上是一种不同于其他算法新的算法。实验结果表明,与传统方法相比,该方法能检测出更多的边缘,并且算法实现简单,检测出的边缘清晰。With the results of RGB color space partition,the color information quantity of a pixel in the RGB color space is defined.Calculate the pixel′s information quantity in the correlated neighborhood,then determine whether the pixel is the edge point or not.This edge detection method,to a certain extent,reasonably considers the correlation of all the relevant components of the color.It also transforms the vector space calculation to scalar calculation.Experimental results show that compared with traditional methods,the novel method can detect more edges which are clearer and can be realized simply.
