Evaluation of swallowing has been made possible by cine-Magnetic resonance (MR) imaging with high time resolution. However, the spatial resolution in cine-MR imaging remains inadequate for the detection of anatomical structures. Therefore, it is necessary to refer to static MR images in conjunction with cine-MR imaging. The aim of this study was to determine which MR parameters were appropriate...

In the latest years, multifractal analysis has been applied to image analysis. The multifractal framework takes advantage of multiscaling properties of images to decompose them as a collection of different fractal components, each one associated to a singularity exponent (an exponent characterizing the way in which that part of the image evolves under changes in scale). One of those components,...

Despite the substantial interest in memory for complex pictorial stimuli, there has been virtually no research comparing memory for static scenes with that for their moving counterparts. We report that both monochrome and color moving images are better remembered than static versions of the same stimuli at retention intervals up to one month. When participants studied a sequence of still images...

It is well known that human skin is a viscoelastic material , and the mechanical and electrophysiological responses to transient indentation have been studied and modelled. For tac-tile display system design, it is also important to determine the perceptual eeects, if any, of skin viscoelasticity. The spatial characteristics and sinusoidal steady state response of the sense of touch have been c...

Current parking space vacancy detection systems use simple trip sensors at the entry and exit points of parking lots. Unfortunately, this type of system fails when a vehicle takes up more than one spot or when a parking lot has different types of parking spaces. Therefore, I propose a camera-based system that would use computer vision algorithms for detecting vacant parking spaces. My algorithm...

This paper proposes motion prediction in single still images by learning it from a set of videos. The building assumption is that similar motion is characterized by similar appearance. The proposed method learns local motion patterns given a specific appearance and adds the predicted motion in a number of applications. This work (i) introduces a novel method to predict motion from appearance in...

We use combinations of feedforward networks trained to recognize emotions in face images to achieve excellent generalization. Networks trained with an input encoding of face features (eyes and mouth) achieved about an 84% generalization rate on novel faces. A similar encoding technique applied to the entire face with the same number of parameters achieved only a 60% generalization rate. This su...

We consider dynamic scenes consisting of moving points whose motion is constrained to happen in one of a pencil of planes. This is for example the case when rigid objects move independently, but on a common ground plane (each point moves in one of a pencil of planes parallel to the ground plane). We consider stereo pairs of the dynamic scene, taken by a moving stereo system, that allow to obtai...

UNLABELLED The aim of this article was to study the physiopathology of tumoral uptake of 111In-pentetreotide using factorial analysis of dynamic series (FADS) and to assess the usefulness of this analysis in somatostatin receptor scintigraphy. METHODS Forty-one patients were included, 24 women and 17 men. After intravenous injection of 111 MBq 111In-pentetreotide, dynamic image acquisition (6...

A recently developed SHG microendoscope allows for in vivo imaging of sarcomeres, the basic contractile unit of muscle, in humans for the first time. The static images and dynamic line scans over time provide important information about muscle function and health. The goal of this project was to extract length from static images and dynamic timing properties from dynamic images as automatically...
