摘要
The image compression is required to reduce the size and transmission bandwidth. The wavelet transform-based image compression is more preferable than other techniques such as DCT. The biorthogonal wavelets are more preferable than orthogonal wavelets due to symmetry property and flexibility. This paper proposes image compression using biorthogonal wavelets. The various biorthogonal wavelets are applied to image compression. The bior1.3 wavelet has the highest PSNR and lowest computation time. The bior1.3 wavelet is superior wavelet out of all the biorthogonal wavelets for image compression.
