代码说明:

说明:  边缘检测是图像处理和计算机视觉中的基本问题,边缘检测的目的是标识数字图像中亮度变化明显的点。图像属性中的显著变化通常反映了属性的重要事件和变化。这些包括(i)深度上的不连续、(ii)表面方向不连续、(iii)物质属性变化和(iv)场景照明变化。边缘检测是图像处理和计算机视觉中,尤其是特征提取中的一个研究领域。 一阶:?Roberts Cross算子,Prewitt算子,Sobel算子, Kirsch算子,罗盘算子; 二阶: Marr-Hildreth,在梯度方向的二阶导数过零点,Canny算子,Laplacian算子。(Edge detection is a basic problem in image processing and computer vision. Significant changes in image attributes usually reflect significant events and changes in attributes. These include (I) discontinuities in depth, (ii) discontinuities in surface orientation, (iii) changes in material properties, and (iv) changes in scene lighting. Edge detection is a research field in image processing and computer vision, especially in feature extraction.)
