In this paper, a new metric called despeckling structure loss (DSL) is proposed for
performance assessment of despeckling algorithms with a focus on the preservation of …

Echocardiography is very commonly utilized in the diagnosis of cardiac abnormalities but it
being an ultrasound based imaging modality, comes with inherent curse of speckle noise. It …

Chronic liver diseases are fifth leading cause of fatality in developing countries. Early
diagnosis is important for timely treatment and to salvage life. Ultrasound imaging is …

Image enhancement is an essential phase in many image processing algorithms. In any
image de-noising algorithm, it is a major concern to keep the interesting structures of the …

Feature preserved enhancement is of great interest in medical ultrasound images. Speckle
