Noise Level Estimation for Overcomplete Dictionary Learning Based on Tight Asymptotic Bounds
Rui Chen, Changshui Yang, Huizhu Jia +1
In this letter, we address the problem of estimating Gaussian noise level from the trained dictionaries in update stage. We first provide rigorous statistical analysis on the eigen…

Bayer Demosaicking Using Optimized Mean Curvature over RGB channels
Rui Chen, Huizhu Jia, Xiange Wen +1
Color artifacts of demosaicked images are often found at contours due to interpolation across edges and cross-channel aliasing. To tackle this problem, we propose a novel demosaick…

Learning a collaborative multiscale dictionary based on robust empirical mode decomposition
Rui Chen, Huizhu Jia, Xiaodong Xie +1
Dictionary learning is a challenge topic in many image processing areas. The basic goal is to learn a sparse representation from an overcomplete basis set. Due to combining the adv…
