Evaluating Perceptually Prefiltered Video

Touradj Ebrahimi

Perceptual prefiltering is the process of enhancing relevant portions of an image or of a video, and of simplifying contextual information in order to improve the perceived quality or the compression ratio. In this paper, we discuss the results of subjecti ...

SPIE2005

We present an MPEG--7 compliant description of video sequences for scalable transmission and reconstruction. The proposed method is content-based and permits efficient and flexible video coding while keeping the benefits of textual descriptions in database ...

Point Matching as a Classification Problem for Fast and Robust Object Pose Estimation

Pascal Fua, Vincent Lepetit, Julien Pilet

We propose a novel approach to point matching under large viewpoint and illumination changes that is suitable for accurate object pose estimation at a much lower computational cost than state-of-the-art methods. Most of these methods rely either on using a ...

A Hierarchical Keyframe User Interface for Browsing Video over the Internet

Daniel Gatica-Perez, Jean-Marc Odobez

We present an interactive content-based video browser allowing fast, non linear and hierarchical navigation of video over the Internet through multiple levels of key-frames that provide a visual summary of video content. Our method is based on an XML frame ...

Semantic Segmentation and Description for Video Transcoding

Touradj Ebrahimi

We present an automatic content-based video transcoding algorithm which is based on how humans perceive visual information. The transcoder support multiple video objects and their description. First the video is decomposed into meaningful objects through s ...

Algorithms for Video Structuring

Daniel Gatica-Perez, Jean-Marc Odobez

Video structuring aims at automatically finding structure in a video sequence. Occupying a key-position within video analysis, it is a fundamental step for quality indexing and browsing. As a low level video analysis, video structuring can be seen as a ser ...

A clustering technique for the identification of piecewise affine and hybrid systems

Giancarlo Ferrari Trecate

In this paper we focus on the identification of discrete-time hybrid systems in the Piece-Wise Affine (PWA) form. This problem can be formulated as the reconstruction of a possibly discontinuous PWA map with a multi-dimensional domain. In order to achieve ...

Perceptual Quality Measure using a Spatio-Temporal Model of the Human Visual System

Olivier Verscheure

This paper addresses the problem of quality estimation of digitally coded video sequences. The topic is of great interest since many products in digital video are about to be released and it is thus important to have robust methodologies for testing and pe ...
