An image denoising and fusion algorithm based on steerable filters is presented. A quadrature filter pair is designed, which consists of a steerable filter and its Hilbert transform, to analyze the dominant orientation and local orientation energy in registered images. By using this quadrature pair, speckle noise can then be found out according to their singularity and nondirection properties. And then a local median filter is designed to remove these speckle noises. Simultaneously, significant image characters are fused via weighted averaging method based on local orientation energy. Results show that the signal noise ratio could increase by 50% to 80%, and those significant image characters are preserved well and enhanced obviously.
