Single image super-resolution of medical ultrasound images using a fast algorithm
2016 IEEE 13th International Symposium on Biomedical Imaging (ISBI)
This paper addresses the problem of super-resolution (SR) for medical ultrasound (US) images. Contrary to device-based approaches, we investigate a post-processing method to invert the direct linear model of US image formation. Given the ill-posedness of single image SR, we proposed an ℓp-norm (1 ≤ p ≤ 2) regularizer for the US tissue reflectivity function/image to be estimated. To solve the associated optimization problem, we propose a novel way to explore the decimation and blurring operatorsdoi:10.1109/isbi.2016.7493310 dblp:conf/isbi/ZhaoWBKT16 fatcat:232534mnj5hzbhnoac6pq4vc5u
