Uncertainty Learning in Kernel Estimation for Multi-stage Blind Image Super-Resolution
TL;DR: Zhang et al. as mentioned in this paper proposed a joint Maximum a Posteriori (MAP) approach for estimating the unknown kernel and high-resolution image simultaneously, which introduces uncertainty learning in the latent space when estimating the blur kernel.
Proceedings ArticleDOI
Semi-automatic image registration using harris corner detection and RANdom SAmple Consensus (RANSAC)
TL;DR: The results showed that the combination between cross correlation function and feature-based methods almost give the same results of traditional method but with low processing time.
Proceedings ArticleDOI
Wideband DOA estimation based on sparse representation — An extension of l 1 -SVD in wideband cases
TL;DR: A new wideband DOA estimation model is introduced, instead of processing each subband individually, the whole frequency information of the received signal is combined and, to utilize the same sparsity among angle spectrums with different subbands, a novel sparsity constraint is proposed.

Angel estimation via frequency diversity of the SIAR radar based on Bayesian theory
TL;DR: The Bayesian maximum posteriori estimation with l2-norm weighted constraint is utilized to achieve the equivalent uniform array echo and confirms the advantage of SIAR radar both in array expansion and angle estimation.
