关于这个校正设计的程序,我原本打算做3个版本的。第一个就是现在传上来的这个。这个版本,提供了设计思路的由来和适当的过程的引导,但一些计算步骤由使用者自己来完成。我做这个版本的目的是希望,使用者能通过这个程序的使用明白校正的设计思路,至少是从我理解的程度上去理解。如果以后的师弟、师妹们能通过使用这个程序,更加轻松的掌握校正的方法。我就觉得我做了一件意义重大的贡献,我会感到自豪。所以也希望李老师能对其中的错误和不足进行指正。第二个版本是第一个版本的简化版,只给过程的引导,不给设计思路,主要是给用过第一个版本的同学一个加深联系的途径。(i don t know)

研究表明,构成K一L变换矩阵的向量也就是ToePhtz矩阵的特征向量。与此同时,离散
余弦变换矩阵逼近于ToePutz矩阵的特征向量矩阵,所以离散余弦变换矩阵与自然图像的
K一L变换矩阵十分相似。经过离散余弦变换后的变换系数块的协方差矩阵Cy非常接近对角

反映了自然图像大部分区域变化不大,亮度突变只占少数,即图像能量以低频成分为主的特
性。通过变换后的量化,舍弃对视觉效果影响较小的次要信息,可达到进一步的压缩效果。
虽然从去相关性能的意义上讲,DCT是一种次于K一L变换的准最佳变换,但是从算法实现的角度来看,DCT则远远优于K一L变换。首先,当图像的分块大小确定后,DCT的变换矩阵也就随之确定了,不随输入信号的统计特性变化而变化 其次,二维DCT能够分解成两次一维DCT,有利于硬件实现。
