Research on the application of image fusion and second-generation bandelet transform in image denoising

Effectively geometric representation of images is a significant image denoising tool. In order to obtain a clearer image, we used second-generation bandelet bases to establish the geometric stream represents of images, and combined with the image fusion technology to improve the quality of images. Though the adaptive threshold and global threshold of numerous experiments, and finding a optimal wavelet function to use image fusion operation. This is the innovation of the paper. Therefore, using bandelet and image fusion improve the quality of images. The result of the paper is better than the traditional denoising method, wavelet denoising and bandelet denoising.
