region
- 区域生长法，手动选种子点吗，它是一个迭代的过程，这里每个种子像素点都迭代生长 直到处理过每个像素，因此形成了不同的区域，这些区域它们的边界通过闭合的多边形定义。 在区域生长中的主要问题如下: (1)表示区域的初始化种子的选择:在区域生长过程中，这些不同区域点合适属性的选择。 (2)基于图像具体属性的像素生长不一定是好的分割。在区域生长过程中，不应该使用连通性或邻接信息。 (3)相似性:相似性表示在灰度级中观察在两个空间邻接像素之间或像素集合的平均灰度级间的最小差分，它们将产生不同的区域

二值图像中拐点的实时检测算法
- 数字图像中的拐点通常成为重要的信息载体，因此准确、稳定和实时地检测出拐点便成为拐点检测算法面l临的主要问题，针对该问题，提出了一种新的二值图像中拐点的实时检测算法。该算法与传统基于边界链码的拐点检测算法不同，其是首先构建像素的k(k>8)邻域，并将图像中物体的边界表示为k邻域链码；然后根据曲率定义的差分形式计算各边界点处的曲率；最后通过检测曲率直方图的局部峰值精确定位出拐点，并利用拐角内部像素的颜色统计信息迅速判断出拐点的凸凹性。(The inflection point in the d
