图像中点、线、面特征提取

Distilling characters of dot line and surface in image

介绍图像中的点、线、面的特征提取方法。并具体介绍了角点的特征提取及常规的直线特征提取和一种对直线进行特征提取的新方法。新的直线特征提取方法比常规的直线提取方法能减少计算量,加快运算速度。面特征只介绍了计算公式。

This article introduces the methods of distilling characters of dot line and surface in image. One of these methods is selected to introduce distilling the characters of corner dot. The routine methods of distilling line＇s characters and a new method of distilling the characters of line are introduced. If we contrast new and old methods of distilling the characters of line, we can find that the new method can cut down quantities of account and quicken the speed of operation. Only computer formulae about distilling of the characters of surface are introduced.
