[Special Effectsdct

Description: 继续,这个是,恩,还是和数字水印和图像处理有关系的东西拉,因为最近在做这个拉,恩,之所以这么着急的一下子就上传5个,是因为我真的有一点东西要看一下,看了好长哪方面的资料,可是还是不能搞定,所以要找源码看看啊,所以麻烦站长了,赶紧帮我开通一下拉,谢谢啊!真诚的。 转入正题:这个是一个离散余弦变换的C语言程序,相信数字水印和图像处理方面的编程者对他很熟悉,使用matlab实现他很简单,可是。。。我们用的是VC啊。哈哈,不过没有关系拉,这个我已经搞定了,所以如果你对此还是不很熟悉,那么就看看这个源码吧,直接用也很方便,是对m*n的分块进行的DCT变换,还有反变换,所以使用VC语言的数字水印方面的py赶紧来看看吧! 再次感谢站长。-err

[Graph programpangzi

Description: (1)将整幅图像分成4×4块,计算每一块中所有象素RGB三个颜色通道的颜色平均值,并以此作为该块的代表颜色(主颜色)。 (2)将各块的颜色平均值进行离散余弦变换(DCT),得到DCT系数矩阵。DCT是一种分离的变换,是国际静止图像压缩标准JPEG的基础。由于大多数图像的高频分量较小,相应于图像高频分量的系数经常为零,加上人眼对高频成分的失真不太敏感,所以可用更粗的量化。因此,在一般检索中可以利用部分DCT系数作为特征向量。 (3)对DCT系数矩阵进行之字形扫描和量化,得到DCT系数。 (4)对于R、G、B三个通道,分别从DCT系数中取出4个低频分量,形成12个参数,共同构成该图像的颜色特征向量。-err
