Adaptive Image Compression Based Wavelet Using Space-Frequency Segmentation

We presented a new compression scheme by using the adaptive Space-Frequency Segmentation (SFS) decomposition method as the basis for context-based spatial entropy coders. The context-based entropy techniques were applied in the lossy coding for natural images. The proposed compression scheme for adaptive wavelet coding is combined with spatial encoding. Results showed that the proposed technique gives significantly better image quality compared with other compression rates.
