Abstract
Progressive image transmission under interactive user control is quite effective for low-bit-rate channels. The efficiency increases when significant details are transmitted first. A new criterion to extract them is presented, based on an entropy function which takes into account the features at different levels of a Laplacian pyramid. Results are compared with those given by existing algorithms.
