- 网格化[tessellation]即把凹多边形,包含洞,岛的多边型,或者自交叉多边型划分为简单凸多边形的过程.OpenGL为了能快速渲染多边形,只能直接显示简单凸多边形[多边形中任意两点的连线上的所有点仍属于此多边形],对凹多边或者自交叉多边形渲染结果将不确定。在渲染复杂多边形时,常常需要将复杂多边形分解成容易渲染的简单多边形,OpenGL中的使用函数库中提供网格化的函数以通过多边型轮廓线生成简单多边形,从而渲染复杂多边形。 ,Grid [tessellation] that is conca

- 利用opencv图像库对两幅报纸图像进行拼接,输出拼接结果图。实际的使用过程中可以预先计算参数和变换矩阵以提高效率。拼接的结果图略有重影,如果要消除重影,可以自行修改最后部分的拼接算法,把两幅图叠加改为依据分割线拼接。(Opencv image library is used to connect two newspaper images and output the result of stitching. In actual use, the parameters and the trans
边缘提取
- 边缘提取:边缘检测的基本思想首先是利用边缘增强算子,突出图像中的局部边缘,然后定义象素的“边缘强度”,通过设置阈值的方法提取边缘点集。由于噪声和模糊的存在,监测到的边界可能会变宽或在某点处发生间断。因此,边界检测包括两个基本内容: (1)用边缘算子提取出反映灰度变化的边缘点集。 (2)在边缘点集合中剔除某些边界点或填补边界间断点,并将这些边缘连接成完整的线。(Edge extraction: the basic idea of edge detection is to use edge en
