jpeg encode
论文主要介绍了JPEG的编码和解码过程。该程序的编码部分能把一张BMP格式的图象进行JEPG编码,压缩成以二进制形式保存的文件;通过相应的解码程序又可以把图象解压缩出来。在图象传送过程中,我们经常采用JPEG格式对静态图象进行编码。JPEG基本系统是一种有损编码,无法完全恢复出原图象,信息有一定的丢失,称为有损压缩。尽管我们希望能够无损压缩,但是通常有损压缩的压缩比(即原图象占的字节数与压缩后图象占的字节数之比,压缩比越大,说明压缩效率越高)比无损压缩的高。JPEG编码先把图象色彩RBG变成亮度Y和色度Cr、Cb,它利用人的视觉对色度不敏感的特点,减少一部分色度数据,以达到压缩。 JPEG采取多种编码方式,包含有行程编码(Run Length Coding)和哈夫曼(Huffman)编码,有很高的压缩比。在编码前,先对数据进行分块,离散余弦变换(DCT)及量化,保留能量大的低频信号,丢弃高频信号以达到压缩。解码时,进行熵解码,反量化,反离散余弦变换(IDCT)。
