Abstract

Image restoration processing is to rebuild or restore original images with some prior knowledge according to given degraded images or noise-polluted images. This paper proposed an image filter algorithm based on improved Shearlet Transformation. Firstly, it adopted classical Shearlet Transform to decompose noised image into many sub-wavelets under multi-scale and multi-orientation. Secondly, it weighted each sub-wavelets obtained in first step. Then, by classical Shearlet inverse Transform, a new composite image created which composed from those weighted sub-wavelets. Experimental results shown that proposed algorithm eliminates noise effectively and yields good Peak Signal Noise Ratio (PSNR).
