Achievable information rates for channels with insertions, deletions, and intersymbol interference with i.i.d. inputs
—We propose to use various trellis structures to characterize different types of insertion and deletion channels. We start with binary independent and identically distributed (i....

Sensitivity analysis of parcellation in the joint detection-estimation of brain activity in fMRI
Within-subject analysis in fMRI relies on both (i) a detection step to localize which parts of the brain are activated by a given stimulus type, and on (ii) an estimation step to ...

Ray Markov Random Fields for Image-Based 3D Modeling: Model and Efficient Inference
In this paper, we present an approach to multi-view image-based 3D reconstruction by statistically inversing the ray-tracing based image generation process. The proposed algorithm...
