Novel Sparse Recovery Algorithms for 3D Debris Localization using Rotating Point Spread Function Imagery
Chao Wang, Robert Plemmons, Sudhakar Prasad +2
An optical imager that exploits off-center image rotation to encode both the lateral and depth coordinates of point sources in a single snapshot can perform 3D localization and tra…
Linkage between piecewise constant Mumford-Shah model and ROF model and its virtue in image segmentation
Xiaohao Cai, Raymond Chan, Carola-Bibiane Schonlieb +2
The piecewise constant Mumford-Shah (PCMS) model and the Rudin-Osher-Fatemi (ROF) model are two important variational models in image segmentation and image restoration, respective…
A Convex Model for Edge-Histogram Specification with Applications to Edge-preserving Smoothing
Kelvin C. K. Chan, Raymond H. Chan, Mila Nikolova
The goal of edge-histogram specification is to find an image whose edge image has a histogram that matches a given edge-histogram as much as possible. Mignotte has proposed a non-c…
A two-stage method for spectral-spatial classification of hyperspectral images
Raymond H. Chan, Kelvin K. Kan, Mila Nikolova +1
This paper proposes a novel two-stage method for the classification of hyperspectral images. Pixel-wise classifiers, such as the classical support vector machine (SVM), consider sp…
Non-convex optimization for 3D point source localization using a rotating point spread function
Chao Wang, Raymond Chan, Mila Nikolova +2
We consider the high-resolution imaging problem of 3D point source image recovery from 2D data using a method based on point spread function (PSF) engineering. The method involves…
