基于DFT、DCT和小波变换图像压缩与Matlab实现

摘要

简述DFT、DCT、小波变换原理，并通过Matlab模拟DFT、DCT、小波变换过程，进而研究了DCT、DFT、小波变换在图像变换中的差异。通过对比实验结果，得出JPEG静态图像压缩最佳方案。%The principle of DFT,DCT,wavelet transformation,.Simulating the process of DFT,DCT and wavelet transformation witn Matlab and then research the differences among DFT,DCT and wavelet transformation.Through the comparison of results , get the best solution to JPEG static image compressed.
