Abstract :
Independent component analysis (ICA) along with a differential pulse-code modulation (DPCM) system has been used for secure transmission of medical images. The advantage of this approach is the ability to compress images that will be transmitted securely. The combined DPCM-ICA system can be designed with varying levels of quantization, however, image quality is sacrificed for low quantization levels.
