jpeg dumper. dumps the jpeg stream. uses the procedures from the jpeg standard. that s all.

The EZW encoder is based on progressive encoding to compress an image into a bit stream with increasing accuracy. This means that when more bits are added to the stream, the decoded image will contain more detail, a property similar to JPEG encoded i

matlab编程实现JPEG编码，输出为DC系数的码流、AC系数的码流、图像的高度宽度。-matlab programming JPEG encoding, the output stream for the DC coefficients, AC coefficients of the code stream, the image height width.

实现jpeg压缩和解压缩,将彩色图像进行颜色空间转换、对不同的颜色分量进行不同的采样、对于3个分量进行8×8的DCT变换、对DCT系数矩阵按照JPEG推荐的量化表进行量化；对量化后的系数进行Z形扫描，最后进行熵编码，形成码流，计算比特数，和压缩比。解压从量化后的DCT系数表开始逆向进行-Jpeg compression and decompression, the color image is a color space conversion, the different color compo
