| Abstract: | The statistical characteristics of wavelet transform c oefficients are analyzed and the models of the statistical characteristics for the sensed image and ordinary image are established. By analyzing the relations hip between the data compression ratio and the visual perceptual threshold, the ultimate compression ratio of the sensed image without visual perceptual distort ion is studied. The image compression experiments with real sensed images and o rdinary ones demonstrat the accuracy and effectiveness of the theroy. |
