- W2359696588 abstract "For the possibility and necessity of digital image compression,this paper has discussed the principle of three usual algorithms applied to digital image compression. Including Differential Pusle Code Modulation(DPCM), Discrete Cosine Transform(DCT), Discrete Wavelet Transform(DWT). What′s more, for researching their performance on image compression, it has given out the probability distributing of coefficient, standard difference, information entropy, mean squared error, and the percentage of zero coefficient after processing the picture Lena(512×512) with them on Matlab.It has a comparison of these three algorithms in detail, and has analysed the cause of leading to their different performance, this contributes to further learning and searching the better algorithms for digital image compression." @default.
