Blind Audio-Visual Source Separation Using Sparse Redundant Representations
Pierre Vandergheynst, Gianluca Monaci, Anna Llagostera Casanovas
This report presents a new method to confront the Blind Audio Source Separation (BASS) problem, by means of audio and visual information. In a given mixture, we are able to locate the video sources first and, posteriorly, recover each source signal, only w ...
2006Method and system for combining video with spatio-temporal alignment
Martin Vetterli, Paolo Prandoni, Serge Ayer
Given two video sequences (IS1, IS2), a composite video sequence can be generated which includes visual elements from each of the given sequences, suitably synchronized and represented in a chosen focal plane (figure 1). For example, given two video sequen ...
2006A multimodal approach to extract optimized audio features for speaker detection
Jean-Philippe Thiran, Murat Kunt, Torsten Butz, Patricia Besson
We present a method that exploits an information theoretic framework to extract optimal audio features with respect to the video features. A simple measure of mutual information between the resulting audio features and the video ones allows to detect the a ...
IEEE2005Semantic Video Analysis for Adaptive Content Delivery and Automatic Description
We present an encoding framework which exploits semantics for video content delivery. The video content is organized based on the idea of main content message. In the work reported in this paper, the main content message is extracted from the video data th ...
2005Effect of Segmentation Method on Video Retrieval Performance
David Grangier, Alessandro Vinciarelli
This paper presents experiments that evaluate the effect of different video segmentation methods on text-based video retrieval. Segmentations relying on modalities like speech, video and text or their combination are compared with a baseline sliding window ...
