扫描线填充法： 1、原理：该算法利用了扫描线的相关性和多边形边的相关性，而不是逐点进行处理。 2、扫描线的相关性：某条扫描线上相邻的象素，几乎都具有同样的内外性质，这种性质只有遇到多边形边线与该扫描线的交点时才会发生改变。 3、边的相关性：由于相邻扫描线上的交点是与多边形的边线相关的。对同一条边，前一条扫描线yi与该边的交点为xi，而后一条扫描线yi+1=yi+1与该边的交点则为xi+1=xi+1/m，利用这种相关性可以省去大量的求交运算。 边相关扫描线填充算法的实现需要建立两个表：边表（ET）和活动边表（AET）。-err

这是一个老外写的利用曲率来识别硬币的MATLAB程序。作者所在国家的硬币偏黄色，拍摄的时候反光比较少，容易识别，国内的硬币则不然，特别是1块和1毛的硬币，很容易产生反光，因此识别时要消除反光。但是这种识别方法简单，实时性好，不失一种良好的参考。国内用图像识别硬币作的还很少，一般都是通过考查硬币的材质来判断硬币，成本较高，而软件来识别成本较低，但是有一定的难度。-This is a foreigner to write the use of curvature to identify the coins of the MATLAB program. The author coins the country where the yellow side, when shooting less reflective, easy identification, the coins are not domestic, especially in a coin and one of Mao, it is easy to produce reflective, so to eliminate reflective recognition. However, this identification method is simple, real-time, and losing a good reference. Domestic use image recognition for the few coins, coins are generally through the test material to determine the coin, the higher the cost, and software to identify lower-cost, but have a certain degree of difficulty.
