Description: 实现基本JPEG的压缩和编码分三个步骤:
1. 首先通过DCT变换去除数据冗余；
2. 使用量化表对DCT系数进行量化；
3. 对量化后的系数进行Huffman编码。-Realize the basic JPEG compression and encoding is divided into three steps: 1. First of all, through the DCT transform to remove data redundancy 2. The use of quantization table of quantization DCT coefficients 3. Quantization coefficients after Huffman coding. Platform: |

Description: the attached utility is a work I ve submitted to the university
It shows what a jpeg compression is all about.
the function implements the DCT transform, using a matrix operator.
note that matlab has a function for the DCT and iDCT transforms
that might be more efficient.-the attached utility is a work I ve submitted to the universityIt shows what a jpeg compression is all about.the function implements the DCT transform, using a matrix operator.note that matlab has a function for the DCT and iDCT transforms that might be more efficient .
