Speckle Noise Suppression Techniques for Ultrasound Images

Speckle is a multiplicative noise that degrades the visual evaluation in ultrasound imaging. In medical ultrasound image processing, speckle noise suppression has become a very essential exercise for diagnose. The recent advancements in ultrasound devices necessitate the need of more robust despeckling techniques for enhancing ultrasound medical imaging in routine clinical practice. Many denoising techniques have been proposed for effective suppression of speckle noise. This paper compiles the performance of various techniques in medical B-mode ultrasound images.
