Abstract

Progressive transmission of biomedical images through a wireless network is extremely useful for fast retrieval of the region of interest (RoI) from large images. To do that, the images have to be compressed as much as possible and then streamed to the receiver. The RoIs are streamed and then sent with a higher priority order. Such a process should not impose any visible error to the data, which may contain important clinical information. The compression has been performed by means of embedded zero tree wavelet (EZW) encoding and a MATLAB-based TCP/IP connection has been established for demonstrating the progressive transmission of the data.
