Compression Techniques
INTRODUCTION This research describes an image representation technique that entails progressive refinement of user specified regions of interest (ROI) of large images. Progressive refinement of original quality can be accomplished in theory. However, due to heavy burden on storage resources for our applications, we restrict the refinement to about 25% of the original data resolution. Wavelet decomposition with Vector Quantization (VQ) of the high frequency components and JPEG/DCT compression of low frequency component is used
