A Learning State-Space Model for Image Retrieval
This paper proposes an approach based on a state-space model for learning the user concepts in image retrieval. We first design a scheme of region-based image representation based on concept units, which are i...

Audiovisual Speech Synchrony Measure: Application to Biometrics
Speech is a means of communication which is intrinsically bimodal: the audio signal originates from the dynamics of the articulators. This paper reviews recent works in the field of audiovisual speech, and mor...

Combining Low-Level Features for Semantic Extraction in Image Retrieval
An object-oriented approach for semantic-based image retrieval is presented. The goal is to identify key patterns of specific objects in the training data and to use them as object signature. Two important asp...

A Novel Face Segmentation Algorithm from a Video Sequence for Real-Time Face Recognition
The first step in an automatic face recognition system is to localize the face region in a cluttered background and carefully segment the face from each frame of a video sequence. In this paper, we propose a f...
