VC 语言 C＋＋图象处理
采用DCT变换压缩方法
游程压缩界面中 显示出压缩比.
图象要能还原
界面美观,源代码有详细的注释,容易看懂
实现DCT变换步骤为:
1 灰度图象数组进行分块: 按8X8 距阵分割
2 对每个8X8距阵进行DCT变换 3
量化变换 (有损)
4 对进行量化的DCT距阵进行游程压缩
解压:上步骤的逆过程解压模块需 讨论偏差
VC Language C + + Image Processing
Compression method using DCT transform
Run-length compression interface shows compression ratio.
Images must be able to restore the
Beautiful interface, source code detailed notes, easy to understand
DCT transform steps to achieve:
A gray-scale image array block: According to 8X8 matrix partition
2 pairs of each 8X8 matrix for DCT-3
Quantization transform (harmful)
4 pairs of the DCT matrix to quantify the run-compression
Extract: on the steps of the reverse process of extracting the module to be discussed by bias
