犯错
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

数字水印处理系统主要由水印嵌入和水印检测两个过程。(1)水印嵌入过程为:数字水印(X)、原图像(I)和密钥/公钥(K)通过数字水印嵌入算法形成嵌入水印后的图像(I*)。 (2)水印检测过程为:数字水印(X)、水印图像(I*)和密钥/公钥(K)通过数字水印检测算法检测出数字水印或有无水印。该程序调试已通过!-Digital watermarking system mainly consists of watermark embedding and watermark detection of the two processes. (1) The watermark embedding process as follows: Digital watermarking (X), the original image (I) and key/public key (K) by digital watermark embedding algorithm to form watermarked image (I*). (2) The watermark detection process is as follows: Digital watermarking (X), the watermark image (I*) and key/public key (K) by digital watermark detection algorithm to detect whether the digital watermark or watermark. The program debugging has passed!
