A cable-driven parallel mechanism for capturing object appearance from multiple viewpoints
- Université
, 2007
"... This paper presents the full proof of concept of a system for capturing the light field of an object. It is based on a single high resolution camera that is moved all around the object on a cable-driven end-effector. The main advantages of this system are its scalability and low interference with sc ..."

The Determinants of Credit Spread Changes.
- Journal of Finance
, 2001
"... ABSTRACT Using dealer's quotes and transactions prices on straight industrial bonds, we investigate the determinants of credit spread changes. Variables that should in theory determine credit spread changes have rather limited explanatory power. Further, the residuals from this regression are ..."

are highly crosscorrelated, and principal components analysis implies they are mostly driven by a single common factor. Although we consider several macro-economic and financial variables as candidate proxies, we cannot explain this common systematic component. Our results suggest that monthly credit spread
Appearance-Based Active Object Recognition
- Image and Vision Computing
"... We present an efficient method within an active vision framework for recognizing objects which are ambiguous from certain viewpoints. The system is allowed to reposition the camera to capture additional views and, therefore, to improve the classification result obtained from a single view. The appro ..."

Discriminative Mixture-of-Templates for Viewpoint Classification
- EUROPEAN CONFERENCE ON COMPUTER VISION
, 2010
"... Object viewpoint classification aims at predicting an approximate 3D pose of objects in a scene and is receiving increasing attention. State-of-the-art approaches to viewpoint classification use generative models to capture relations between object parts. In this work we propose to use a mixture of ..."

Simultaneous object recognition and segmentation from single or multiple model views
- Int. J. Comput. Vision
"... Abstract. We present a novel Object Recognition approach based on affine invariant regions. It actively counters the problems related to the limited repeatability of the region detectors, and the difficulty of matching, in the presence of large amounts of background clutter and particularly challeng ..."

the correct matches from the wrong ones. Hence, recognition and segmentation are achieved at the same time. The approach includes a mechanism for capturing the relationships between multiple model views and exploiting these for integrating the contributions of the views at recognition time. This is based
Coupled-View Active Appearance Models
, 2000
"... This paper describes building models which represent the appearance of an object (in particular, a face) as seen from two or more di erent viewpoints simultaneously. A small number of 2D linear statistical models are sucient to capture the shape and appearance of a face from a wide range of viewpoin ..."

Appears in the SIGGRAPH Asia 2011 Proceedings. Single View Reflectance Capture using Multiplexed Scattering and Time-of-flight Imaging
"... Figure 1: By analyzing indirectly scattered light, our approach can recover reflectance from a single viewpoint of a camera and a laser projector. (a) To recover reflectance of patches on the back wall, we successively illuminate points on the left wall to indirectly create a range of incoming direc ..."

. This paper introduces the concept of time-of-flight reflectance estimation, and demonstrates a new technique that allows a camera to rapidly acquire reflectance properties of objects from a single viewpoint, over relatively long distances and without encircling equipment. We measure material properties
