A Diversified Denoising System for Biomedical Images

In this paper, we propose an image denoising system which reduce the speckle noise in medical images, while preserving the image features. The proposed denoising methods are based on wavelets functions. We have chosen denoising methods based on the Dual Tree Complex Wavelet Transform (DTCWT) and three variants of the bishrink filter. More, we propose an original denoising method that takes into account the textural and structural properties of the analyzed images.
