Abstract

Ultrasound imaging, also known as ultrasound scanning or sonography, is a very popular medical test that helps medical doctors diagnose and treat medical conditions of their patients. However, one common problem that persists is that ultrasound images suffer from speckle noise that degrades their quality. In this paper we present an enhancement technique for ultrasound images by making use of three consecutive frames extracted from an ultrasound video. The technique uses the optical flow algorithm to reconstruct an intermediate frame based on the preceding and the following frames. The reconstructed image is then utilized to enhance the middle frame by mean of fusion. Based on the test, the best result is achieved using Lukas-Kanade optical flow and average operator.
