Comparative study between different denoising filters for speckle noise reduction in ultrasonic b-mode images

Image denoising involves processing of the image data to produce a visually high quality image. The denoising algorithms may be classified into two categories, spatial filtering algorithms and transform domain algorithms. In this paper a comparative study between different denoising filters for speckle noise reduction in ultrasonic b-mode images based on calculating the Peak Signal to Noise Ratio (PSNR) value as a metric is presented.
