A generalized divergence measure for robust image registration
IEEE Transactions on Signal Processing, 51(5), 1211–1220.
TL;DR:
This paper defines a new generalized divergence measure, namely, the Jensen-Renyi (1996, 1976) divergence, and proposes a new approach to the problem of image registration based on it, to measure the statistical dependence between consecutive ISAR image frames.

Geodesic object representation and recognition
In B. Hamza & H. Krim (Eds.), Discrete geometry for computer imagery: 11th International Conference, DGCI 2003, Naples, Italy, November 19-21, 2003 (Vol. 2886, pp. 378–387).
Ed(s): . B. Hamza & H. Krim n
TL;DR:
A shape signature that captures the intrinsic geometric structure of 3D objects is described, based on a global geodesic distance defined on the object surface, and takes the form of a kernel density estimate.

2003 chapter
Image registration and segmentation by maximizing the Jensen-Renyi divergence
In M. F. A. Rangarajan & J. Zerubia (Eds.), Energy minimization methods in computer vision and pattern recognition (Vol. 2683, pp. 147–163).
Ed(s): M. A. Rangarajan & J. Zerubia
TL;DR:
This paper analyzes the theoretical properties of the Jensen-Renyi divergence which is defined between any arbitrary number of probability distributions and derives its maximum value, and also some performance upper bounds in terms of the Bayes risk and the asymptotic error of the nearest neighbor classifier.

2002 journal article
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.

2001 journal article
A variational approach to maximum a posteriori estimation for image denoising
Energy Minimization Methods in Computer Vision and Pattern Recognition: Third International Workshop, EMMCVPR 2001, Sophia Antipolis, France, September 3-5, 2001: Proceedings, 2134, 19–33.
Ed(s): J. M. Figueiredo & A. Jain
TL;DR:
A variational filter called Huber gradient descent flow is proposed, which yields the solution to a Huber type functional subject to some noise constraints, and the resulting filter behaves like a total variation anisotropic diffusion for large gradient magnitudes and like an isotropic diffusion for small gradient Magnitudes.
