Today, there is almost no area of technical endeavor that is not impacted in
some way by digital image processing.We can cover only a few of these applications
in the context and space of the current discussion. However, limited as
it is, the material presented in this section will leave no doubt in the reader’s
mind regarding the breadth and importance of digital image processing.We
show in this section numerous areas of application, each of which routinely utilizes
the digital image processing techniques developed in the following chapters.
Many of the images shown in this section are used later in one or more of
the examples given in the book. All images shown are digital.

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
阵,即除了对角线元素以外,其它很多元素都近似为0,并且在左上角集中了主要能量。这
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。
