Learning Complex and Sparse Events in Long Sequences
The Hierarchical Hidden Markov Model (HHMM) is a well formalized tool suitable to model complex patterns in long temporal or spatial sequences. Even if effective algorithms are ava...

Spatiotemporal Stereo via Spatiotemporal Quadric Element (Stequel) Matching
Spatiotemporal stereo is concerned with recovery of the 3D structure of a dynamically changing scene from a sequence of stereo images. This paper aims at computing temporally coh...

From Separation Logic to First-Order Logic
Separation logic is a spatial logic for reasoning locally about heap structures. A decidable fragment of its assertion language was presented in [1], based on a bounded model prope...

Curved feature metrics in models of visual cortex
We study the relation between maps of a high-dimensional stimulus manifold onto an essentially two-dimensional cortical area and low-dimensional maps of stimulus features such as ...
