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 …
