Abstract—In medical image processing, image denoising has become a very essential exercise all through the diagnose. Negotiation between the preservation of useful diagnostic information and noise suppression must be treasured in medical images. In certain cases, for instance in Ultrasound images, the noise can restrain information which is valuable for the general practitioner. The success of ultrasonic examination depends on the Image quality. In case of ultrasonic images a special type of acoustic noise, technically known as speckle noise, is the major factor of image quality degradation. Many denoising techniques have been proposed for effective suppression of speckle noise. This paper presents the performance analysis of various schemes for suppressing speckle noise in Ultrasound images in terms of the assessment parameters PSNR and Equivalent Number of Looks (ENL).
Index Terms—Medical image processing, image enhancement, ultrasonic imaging, speckle noise, ultrasound speckle reduction, speckle filtering.
