Double Wavelet Transform Method Utilized Picture Compression and Assortment


With the development of information technology, the rapid development of microelectronics technology, picture information acquisition and use is also increasing, sensor technology also unceasingly to reform. A single sensor information obtained is limited, often can not meet the actual needs, in addition, different sensors have the advantage of the imaging principle and its unique, as in color, shape characteristics, band access, spatial resolution from the aspects of all have their own characteristics. Registration algorithm is proposed in this paper has better robustness to picture noise, and can achieve sub-pixel accuracy; the registration time has also been greatly improved. In terms of picture fusion, the pictures to be fused through double wavelet transform of different resolution sub picture, using a new picture fusion method based on energy and correlation coefficient. The high frequency picture decomposed using new energy pixels of the window to window energy contribution rate of fusion rules, the low frequency part by using the correlation coefficient of the fusion strategy, finally has carried on the registration of simulation experiments in the Matlab.
