Abstract:
    A limited redundancy discrete wavelet transform method is used in the field of image processing, image fusion and signal processing. The invention firstly designs the filter, which is used respectively in the first class and the subsequent dissociation class, and then takes different sub-sampling rules according to different channels during the process of wavelet dissociation to, and uses the filter corresponding to its positive transformation and super-sampling rules during the process of inverse transformation. The invention, which uses different filter design methods in different class of discrete wavelet transform, and sub-sampling, super-sampling strategies according to different channels, can make the wavelet coefficients to have good invariance and appropriate redundancy. The invention can be applied to image processing, image fusion, signal processing and transformation, which can be used in radar, voice, geographic information processing and other home and military systems.
