Abstract :
The progressive image transmission (PIT) technique has been used to alleviate the communication problem related to transmit large volume of medical image data. In this study, we propose a novel PIT algorithm based on wavelet transform, DPCM coding and non-uniform scalar quantization. Experimental results have confirmed the efficiency of the proposed scheme. The achieved bit rate for the first recognizable picture can be as low as 0.05 bit/pixel transmitted in less than 1.0 second for a 512times512 256-gray scale medical image. The reconstructed image shows higher quality than that obtained by the set partitioning in hierarchical trees (SPIHT) algorithm, which makes it a winning choice for medical image transmission through low speed communication channels
