Sparse signal processing has already been introduced to synthetic aperture radar (SAR), which shows potential in improving imaging performance benify toyota based on raw data or a complex image.In this paper, the relationship between a raw data-based sparse SAR imaging method (RD-SIM) and a complex image-based sparse SAR imaging method (CI-SIM) is
ABSTRACT Objective: The objective of this study is to compare the total costs of surgery and contraderm radiofrequency (RF) ablation for the treatment of benign thyroid nodules.Materials and methods: This is a prospective randomized study comparing cases treated with US-guided RF ablation (cases) and surgery (control).They were selected and allocat
This paper presents a reduced-complexity deterministic annealing (DA) approach for vector quantizer (VQ) design by using soft information processing with simplified assignment measures.Low-complexity distributions are designed to mimic the Gibbs distribution, where the latter is the optimal distribution used in the standard DA method.These low-comp
