Design of a low light level image compression circuit based on improved EZW algorithm

A Low light level (LLL) image compression circuit is studied based on improved Embedded Zero-tree Wavelet (EZW) algorithm to improve the real-time transmission performance. The improved EZW compression algorithm is implemented on TMS320C6455 DSP chip based on the theory of wavelet transform. And then a transmitter and receiver is designed which can transmit dynamic image in real time over a distance of 2 kilometers. Experiment and numerical results are presented to validate the efficiency and accuracy of this method.
