Évaluation de la robustesse des descripteurs de texture pour la segmentation des images de documents anciens

For the segmentation of ancient digitized document images, it has been shown that texture feature analysis is a consistent choice for meeting the need to segment a page layout under significant and various degradations. In addition, it has been proven that the texture-based approaches work effectively without hypothesis on the document structure, neither on the document model nor the typographi...

Recherche incrémentale à base de points pour la résolution des DEC-POMDPs (présentation courte)

Recent scaling up of decentralized partially observable Markov decision process (DECPOMDP) solvers towards realistic applications is mainly due to approximate methods. Of this family, MEMORY BOUNDED DYNAMIC PROGRAMMING (MBDP), which combines in a suitable manner top-down heuristics and bottomup value function updates, can solve DECPOMDPs with large horizons. The performance of MBDP, however, ca...
