Image denoising based on improved data-driven sparse representation
Dai-Qiang Chen
Sparse representation of images under certain transform domain has been playing a fundamental role in image restoration tasks. One such representative method is the widely used wav…
Fixed Point Algorithm Based on Quasi-Newton Method for Convex Minimization Problem with Application to Image Deblurring
Dai-Qiang Chen
Solving an optimization problem whose objective function is the sum of two convex functions has received considerable interests in the context of image processing recently. In part…
Inexact Alternating Direction Method Based on Newton descent algorithm with Application to Poisson Image Deblurring
Dai-Qiang Chen
The recovery of images from the observations that are degraded by a linear operator and further corrupted by Poisson noise is an important task in modern imaging applications such…
Novel variational model for inpainting in the wavelet domain
Dai-Qiang Chen, Li-Zhi Cheng
Wavelet domain inpainting refers to the process of recovering the missing coefficients during the image compression or transmission stage. Recently, an efficient algorithm framewor…
Fast Linearized Alternating Direction Minimization Algorithm with Adaptive Parameter Selection for Multiplicative Noise Removal
Dai-Qiang Chen, Li-Zhi Cheng
Owing to the edge preserving ability and low computational cost of the total variation (TV), variational models with the TV regularization have been widely investigated in the fiel…
