Information-theoretic active polygons for unsupervised texture segmentation
INTERNATIONAL JOURNAL OF COMPUTER VISION, 62(3), 199–220.
author keywords: region-based active contours; unsupervised segmentation; texture segmentation; polygon evolution; information theoretic measure; electrostatic regularizer
TL;DR:
A new active contour model is developed which nicely ties the desirable polygonal representation of an object directly to the image segmentation process and can robustly capture texture boundaries by way of higher-order statistics of the data and using an information-theoretic measure and with its nature of the ordinary differential equations.

Stochastic differential equations and geometric flows
IEEE TRANSACTIONS ON IMAGE PROCESSING, 11(12), 1405–1416.
author keywords: geometric image and shape flows; stochastic differential equations; nonlinear filtering; shape analysis
TL;DR:
Modifications of the geometric heat equation designed to preserve certain features in these shapes while removing noise are presented, and it is shown how these new flows may be applied to smooth noisy curves without destroying their larger scale features, in contrast to the original geometric heat flow.

Unifying probabilistic and variational estimation
IEEE SIGNAL PROCESSING MAGAZINE, 19(5), 37–47.
TL;DR:
This article presents a variational approach to MAP estimation with a more qualitative and tutorial emphasis and proposes an information-theoretic gradient descent flow which is a result of minimizing a functional that is a hybrid between a negentropy variational integral and a total variation.

Restoration of error-diffused images using projection onto convex sets
IEEE TRANSACTIONS ON IMAGE PROCESSING, 10(12), 1836–1841.
author keywords: error diffusion; inverse error diffusion; inverse halftoning; projection onto convex sets (POCS); restoration
TL;DR:
A novel inverse halftoning method is proposed to restore a continuous tone image from a given half-tone image using a set theoretic formulation where three sets are defined using the prior information about the problem.
