Subject -

The aim of my PhD is to investigate non-parametric models for object tracking and recognition through three key questions :

- How to update a model along the time ?
- How to model a probability density function in a high dimensional space ?
- How to model a probability density function from a very high number of points ?

My subject is available here (french version) and here (english version).

Publications -

Information Theory for Image Inpainting and Blind Spot Filling-in

In Proceedings of VISAPP 2013. Preprint & Poster.
Simulate a well-known optical illusion due to the blind spot.
Fill-in any binary, grayscale or color images thanks to the entropy inpainting principle.

Kernel Selection by Mutual Information for Nonparametric Tracking

In Proceedings of VISAPP 2012. Preprint & Poster.
Learn a set of kernels that fit to any labelled ROI by CMIM.
Track a ROI with a MCMC Particle Filter and compare different sampling strategies.

Interests -

CMIM for Image Segmentation

Another CMIM code to retrieve the features that fit to any image labelling.
Note that a good feature can either belong to the object or not as H(Y) = H(~Y).

Conditional Mutual Information Maximization (CMIM)

CMIM algorithm to select few half-planes that separate binary points.
Read F. Fleuret's paper and check D. MacKay's famous book (Chap. 8).

Capacity-Constrained Voronoï Tesselation

CCVT algorithm to balance the capacities of 3 sites.
Read Capacity-Constrained Voronoï Diagrams in Finite Spaces.

Lloyd's Algorithm

Lloyd's algorithm on a uniform pdf to cluster points.
Look at Capacity-Constrained Voronoï Tesselation (CCVT) too.

Teaching -

- C Programming/Beginning exercises based on Alexandre Guitton's course (2009/2010).

- Control (french) based on Thierry Chateau and Lounis Adouane' course (2012/2013).
