Hybrid image compression scheme based on wavelet transform and adaptive context modeling

A hybrid image compression scheme based on wavelet transform, HVS thresholding and L∞-constrained adaptive context modelling is proposed. This hybrid system combines the strengths of the wavelet transform, the HVS thresholding and the adaptive context modelling to result in a near optimal compression scheme. In the scheme, the image is first decomposed into the multiresolution subimages using the orthogonal wavelet transform; each subimage …
