基于颜色三角形的彩色图像边缘检测

利用像素点的颜色坐标RGB构建像素的颜色三角形,计算该三角形的周长和内角.将周长和内角作为像素点的信息量的度量.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.

Color Image Edge Detection Based on Color Triangle

A method to determine whether a pixel is the edge point of a color image is presented.First,a color triangle of a pixel is constructed with its color coordinates RGB,and then the perimeter and the internal angle of the color triangle which can be seen as the information value of a pixeil is calculated.Last,comparing the value with that in its neighborhood,a pixel is in the edge point or not is determined.This method took the correlation of every color component into account reasonably,and converted the comp...
