指南针边缘检测算法是当前质量最高的边缘检测方法,比CANNY算子效果还要好。具有边缘定位准确,边连续,完整的特点。程序能够得到每一个像素的边的朝向,有利于做进一步的优化应用,例如图像分割等。具体算法过程可参考斯坦福大学麦克博士发表的论文。主要思路就是以每个像素为中心,像罗盘一样转动边,一直找到两边差异最大的朝向。最后把所有的最优朝向连起来成为边缘。

基于肤色的人脸检测MATLAB源代码皮肤检测的最终目标是构建一个决策规则,并以此将图像中的像素划分为肤色和非肤色两类,一般通过引入一个衡量像素点颜色与“标准肤色”的距离而实现的,该距离是由相应肤色建模的方法决定的-Face detection based on skin color skin detection MATLAB source code for the ultimate goal is to build a decision-making rules, and use of the

图像分割是把图像划分成具有实际意义的互补交迭的区域的集合。在图像分割之前,图像区域的数目未知,而在分割后各个区域同时满足均匀性和连通性的条件,故图像分割是一个复杂的过程,目前大多数研究都是针对某一类型图像或者某一具体应用的分割。图像阈值化分割的基本思想是确定一个阈值,然后把每个像素点的像素值和阈值相比较,根据比较的结果把像素划分为两类,前景(1)或背景(0)。该方法的关键是确定一个最优的阈值。常用的阈值确定方法有直接门限法、类间最大方差法(otsu法)、分水岭算法、最小误差法、最大熵法等。该段代
