| 摘 要： | 针对在RGB空间中很难有效区分颜色相似性的问题,通过选择更加符合颜色视觉特性的HSI颜色空间进行图像处理与分析,提出了一种新的色差度量方法,在此基础上设计了一种彩色边缘检测方法。首先计算色度、饱和度、亮度等三个分量的边缘信息,然后对三个分量进行加权得到彩色边缘信息,通过非极大值抑制和阈值选取后,得到彩色图像的边缘。实验结果表明,该方法可以充分利用彩色图像的色度、饱和度和亮度信息来有效地检测彩色边缘。

| Abstract: | Because it is difficulty to evaluate the similarity of two colors from their distance in RGB color space,color image processing is implemented in Hue Saturation Intensity(HSI) space which reflects the features of human vision.A new method of color distance measurement is presented.A novel color edge detection method is designed.The edge information of hue,saturation and intensity are calculated,and the color edge information is obtained combining the component edge information.The color edge detection is ac... |
