Comparison of Filters for Despeckle With Improved Speckle Reducing Antiscopic Diffusion Filter for Ultrasound Images

---Due to the presence of speckle noise leads to the poor quality of the US images. The presence of speckle noise makes it difficult to understand the information contain in the US image hence filtering of US image is required to improve the image quality. The paper gives us the comparison of different filters techniques (linear filter (lf),Anisotropic Diffusion(AD),Nonlinear filter kuwahara(Kuwa) ,median filter(med),hybrid median filter(hmed) , Lee Filter &kaun, frost filter, Wavelet based speckle reduction methods, speckle reducing anisotropic diffusion filter (srad),improved srad(Israd). 65 texture feature, image intensity normalization, 15 image quantitative metrics and image quality evaluation. It is observed that the Israd, improves the image quality of liver, kidney, uterus, live mass ultrasound images.
