Zusammenfassung:	SPECKLE DENOISING SYSTEM FOR ULTRASOUND IMAGES WITH FRAMELET TRANSFORM AND GAUSSIAN FILTER Two Dimensional transforms are used enormously for the reduction of Speckle Noise in Ultrasound Medical Images. The Present Invention disclosed here in uses a Double bank anatomy with Framelet transform combined with Gaussian filter. This combination even consists of fuzzy kind Clustering Approach for Despeckling Ultrasound Medical Images, productively rejects the noise based on the grey scale relative thresholding where Double Filter Bank (DFB) preserves the Edge Information. The Present Invention disclosed here in provided Fuzzy kind Clustering methods to be better than the conventional threshold methods for noise dismissal, gives a reconcilable development as compared to other modern speckle reduction procedures as it preserves the geometric features even after the noise dismissal, would be judged by different quality indicators such as Mean Square Error (MSE), Signal to Noise Ratio (SNR), Signal to Root Mean Square Error (SRMSE), Peak Signal to Noise Ratio (PSNR), Speckle Suppression Index (SSI), Mean Structural Similarity Index (MSSI), Speckle suppression index (SSI), Speckle Signal to Noise Ratio (SSNR), Signal to MSE, Edge Preservation Index (EPI), Quality Index, Average Difference, and Cross Correlation. The Present Invention disclosed here in is Speckle Denoising System for Ultrasound Images with Framelet Transform and Gaussian Filter comprising of Input Image (201), Noise (202), Framelet Transform (203), SVD Transform (204), Double Filter Bank (205), Clustering (206), Inverse Double Filter Bank (207), Gaussian Filter (208), and Inverse Framelet Transform (209) provides the state of art performance in Speckle Noise reduction in Ultrasound Medical Images.
