Image Replica Detection based on Support Vector Classifier

In this paper, we propose a technique for image replica detection. By replica, we mean equivalent versions of a given reference image, e.g. after it has undergone operations such as compression, filtering or resizing. Applications of this technique include ...

Impedance spectroscopy flow cytometry: Model validation

Philippe Renaud, Shady Didier Gawad, Karen Cheung

A number of microfabricated flow cytometry devices have been proposed based on electrical(1,2) or optical(3) detection techniques. On chip marker-free differentiation of cells using impedance spectroscopy was demonstrated between leukocyte sub-populations ...

Assessment of adrenoleukodystrophy lesions by high field MRS in non-sedated pediatric patients

Rolf Gruetter

Early detection of white matter lesions in childhood-onset cerebral adrenoleukodystrophy (ALD) is important as hematopoietic cell transplantation (HCT), currently the only effective treatment, is beneficial only if performed early in the disease course. ...

Lighting Normalization Algorithms for Face Verification

Sébastien Marcel, Guillaume Heusch

In this report, we address the problem of face verification across illumination, since it has been identified as one of the major factor degrading the performance of face recognition systems. First, a brief overview of face recognition together with its ma ...

Intra-Adaptive Motion-Compensated Lifted Wavelets for Video Coding

Pierre Vandergheynst, Oscar Divorra Escoda

This paper investigates intra-adaptive wavelets for video coding with frame-adaptive motion-compensated lifted wavelet transforms. With motion-compensated lifted wavelets, the temporal wavelet decomposition operates along motion trajectories. However, vali ...

Design of Steerable Filters for Feature Detection Using Canny-Like Criteria

Michaël Unser, Mathews Jacob

We propose a general approach for the design of 2D feature detectors from a class of steerable functions based on the optimization of a Canny-like criterion. In contrast with previous computational designs, our approach is truly 2D and provides filters tha ...

Pedestrian head detection using automatic scale selection for feature detection and statistical edge curvature analysis

Jean-Philippe Thiran, Gianluca Antonini

In this report we focus on pedestrian head detection and tracking in video sequences. The task is not trivial in real and complex scenarios where the deformation induced by the perspective field requires a multi-scale analy- sis. Multi-scale shape models f ...

On Performance Evaluation of Face Detection and Localization Algorithms

Jean-Philippe Thiran, Sébastien Marcel, Vlad Popovici, Yann Rodriguez

When comparing different methods for face detection or localization, one realizes that just simply comparing the reported results is misleading as, even if the results are reported on the same dataset, different authors have different views of what a corre ...

Adaptive Hough transform for the detection of natural shapes under weak affine transformations

Jean-Philippe Thiran

This paper introduces a two-steps adaptive generalized Hough transform (GHT) for the detection of non-analytic objects undergoing weak affine transformations in images. The first step of our algorithm coarsely locates the region of interest with a GHT for ...
