Madhuri Gedam, Hetal Amrutia, Nabnita Mandal . Biomedical Ultrasound Image Enhancement using SRAD. International Conference and workshop on Advanced Computing 2013. ICWAC, 2 (June 2013), 0-0.
In this paper we present Speckle Reducing Anisotropic Diffusion (SRAD) technique that uses wavelet decomposition. This technique is able to preserve and enhance edges while smoothing homogeneous regions in ultrasound images. SRAD is applied on various real biomedical ultrasound images with different number of iterations. The performance of SRAD filter is found to be much better than conventional Lee, Frost filters. SRAD gives less MSE, higher PSNR and better FOM. The experiemental results show that this technique works effectively both in terms of speckle reduction, edge preservation and edge enhancement.
