灰度图像的像素值范围在[0,255]之间,如果采用一个像素一个字节的存储方式,势必会造成空间的浪费。如果采用一定的无损压缩算法,可以大大提高减小文件大小,减少存储空间。本程序采用动态规划中图像压缩算法(图像分段合并的思想),设计一个类,实现灰度位图数据的压缩和解压过程-Grayscale pixel values in the range [0,255], if we adopt a pixel one byte is stored, it must lead to

JPEG标准中规定了4种压缩模式[15]:顺序编码(Sequential encoding),渐进编码(Progressive encoding),等级编码(Hierarchical encoding),无损编码(Lossless encoding)。应用最为广泛的为基于DCT变换的顺序编码,也称之为基准模式(Baseline mode),其它几种模式都以此为基础。这里,采用了JPEG基准模式对图像进行压缩,在基准模式中,熵编码采用哈夫曼编码方法。

JPEG本身只有描述如何將一個影像轉換為位元組的數據串流(streaming),但並沒有說明這些位元組如何在任何特定的儲存媒體上被封存起來。JPEG的壓縮方式通常是破壞性資料壓縮(lossy compression),意即在壓縮過程中圖像的品質會遭受到可見的破壞,有一種以JPEG為基礎的標準Lossless JPEG是採用無失真的壓縮方式,但Lossless JPEG並沒有受到廣泛的支援。
