边缘检测
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.)

ngray
自写M函数,做灰度图像的灰度级数及灰度范围的自定义设置。例如:将[0 255]的uint8图像变换成8级灰度的灰度范围为[0 7]图像或者[11.5 25.8]图像。
输出图像为double类,用户可将图像归一化后自行转换为所需类型。(This is a M function written by self, it can be used to rebuild a image with a given number of gray-level and a given gray-scale.
Output image is double class.)
