摘要
彩色图像有亮度、色调和饱和度的信息.为了充分利用彩色图像丰富的信息,在L*a*b*颜色空间中,利用色差梯度算子对彩色图像进行边缘检测.该方法能检测出更符合视觉特性的彩色边缘.实验结果证明了这种方法是有效的,优于基于灰度的边缘检测方法.
Color image possess the full information of brightness, hue and saturation. To take full advantage of the plentiful information of Color image, we established Color image Edge Detection based on color difference gradient operator, within the L * a* b * space. Compared with detection method based on the gradation, it's more effective. What's more, it can detect Color image Edge matching condition of visual characteristic. The methods apply in the areas of detecting edge of monitoring color image.
