Shape and View Independent Reflectance Map from Multiple Views
We consider the problem of estimating the 3D shape and reflectance properties of an object made of a single material from a set of calibrated views. To model the reflectance, we propose to use the View Independent Reflectance Map (VIRM), which is a ...
A Framework for Model-Based Tracking Experiments in Image Sequences
Motris , an integrated system for model-based tracking research, has been designed modularly to study the effects of algorithmic variations on tracking results. Motris attempts to avoid introducing bias into the relative assessment of alternative ...
A Behavioral Analysis of Computational Models of Visual Attention
Robots often incorporate computational models of visual attention to streamline processing. Even though the number of visual attention systems employed on robots has increased dramatically in recent years, the evaluation of these systems has remained ...
Extrapolative Spatial Models for Detecting Perceptual Boundaries in Colour Images
We present a novel approach for automatically building image-specific extrapolative spatial models of non-boundary local energy that can be used to perform local statistical tests to detect perceptual boundaries. The non-boundary model consists of ...
Constraints Between Distant Lines in the Labelling of Line Drawings of Polyhedral Scenes
The machine interpretation of line drawings has applications both in vision and geometric modelling. This paper extends the classic technique of assigning semantic labels to lines subject to junction constraints, by introducing new constraints (often ...
Local Features and Kernels for Classification of Texture and Object Categories: A Comprehensive Study
Recently, methods based on local image features have shown promise for texture and object recognition tasks. This paper presents a large-scale evaluation of an approach that represents images as distributions (signatures or histograms) of features ...
