Ultrasonography is a very prevailing technique for imaging soft tissue structures and organs of human body. But when an Ultrasound image is captured it gets noisy and this added noise is known as speckle noise which hinders the diagnostic process of the radiocologists and doctors. In this paper a method to remove speckle noise from ultrasound images is proposed. So many methods have been proposed in spatial, frequency and wavelet domains. Here new thresholding method in wavelet domain is proposed which takes into account statistical properties of the image using a weighted window. Performance of the proposed algorithm is compared with conventional methods based on Peak Signal to Noise Ratio (PSNR) and Mean Square error (MSE). Results show that proposed algorithm performs better than conventional methods.
