Denoising Of Ultra Sound Images Using Fuzzy-Shrinkage Based Diffusion Filtering
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 5
Abstract
An Ultrasound provides images and information for diagnosis, therapy and prevention. It is the ideal choice for the orthopedic medicine and pain management. Images obtained from the ultrasound suffer from a problem called speckle and this is called as ‘Speckle Noise’ in terms of noise. It is due to multiple coherent reflections from the ambience around the object under consideration. In this paper a fuzzy based diffusion filter is proposed for the reduction of the speckle noise. A fuzzy model is proposed that uses Gaussian function for the shrinkage of diffusion filter. Experimental results prove that the proposed method is efficient in reaching convergence quickly and gives better quantitative result.
