Sparseland Model for Speckle Suppression of B-mode Ultrasound Images

M. Srinivas Ramkrishna Bharath Pachamuthu Rajalakshmi C. Krishna Mohan
Abstract: Speckle is a multiplicative noise which is inherent in medical ultrasound images. Speckles contributes high variance between neighboring pixels reducing the visual quality of an image. Suppression of speckle noise significantly improves the diagnostic content present in the image. In this paper, we propose how sparseland model can be used for speckle suppression. The performance of the model is evaluated based on variance to mean ratio of a patch in the filtered image. The algorithm is tested on both software ...
