Image Deblurring and Super-Resolution by Adaptive Sparse Domain Selection and Adaptive Regularization
TL;DR: Extensive experiments on image deblurring and super-resolution validate that by using adaptive sparse domain selection and adaptive regularization, the proposed method achieves much better results than many state-of-the-art algorithms in terms of both PSNR and visual perception.
Journal ArticleDOI
Context-based, adaptive, lossless image coding
Xiaolin Wu,Nasir Memon +1 more
TL;DR: The CALIC obtains higher lossless compression of continuous-tone images than other lossless image coding techniques in the literature and can afford a large number of modeling contexts without suffering from the context dilution problem of insufficient counting statistics as in the latter approach.
Journal ArticleDOI
An edge-guided image interpolation algorithm via directional filtering and data fusion
Lei Zhang,Xiaolin Wu +1 more
TL;DR: A new edge-guided nonlinear interpolation technique is proposed through directional filtering and data fusion that can preserve edge sharpness and reduce ringing artifacts in image interpolation algorithms.
Journal ArticleDOI
Image Interpolation by Adaptive 2-D Autoregressive Modeling and Soft-Decision Estimation
Xiangjun Zhang,Xiaolin Wu +1 more
TL;DR: A soft-decision interpolation technique that estimates missing pixels in groups rather than one at a time, which preserves spatial coherence of interpolated images better than the existing methods and produces the best results so far over a wide range of scenes in both PSNR measure and subjective visual quality.
Journal ArticleDOI
Canny edge detection enhancement by scale multiplication
Paul Bao,Lei Zhang,Xiaolin Wu +2 more
TL;DR: The technique of scale multiplication is analyzed in the framework of Canny edge detection and the detection and localization criteria of the scale multiplication are derived, finding that at a small loss in the detection criterion, the localization criterion can be much improved by scale multiplication.
