Continuous Time Matching Constraints for Image Streams
Corresponding image points of a rigid object in a discrete sequence of images fulfil the so-called multilinear constraint. In this paper the continuous time analogue of this const...

Estimating the Focus of Expansion in Analog VLSI
In the course of designing an integrated system for locating the focus of expansion (FOE) from a sequence of images taken while a camera is translating, a variety of direct motion ...

What Is the Set of Images of an Object Under All Possible Illumination Conditions?
The appearance of an object depends on both the viewpoint from which it is observed and the light sources by which it is illuminated. If the appearance of two objects is never iden...

Synthesis of Novel Views from a Single Face Image
Images formed by a human face change with viewpoint. A new technique is described for synthesizing images of faces from new viewpoints, when only a single 2D image is available. A...

Determining the Epipolar Geometry and its Uncertainty: A Review
Two images of a single scene/object are related by the epipolar geometry, which can be described by a 3x3 singular matrix called the essential matrix if images’ internal paramete...

Robust Algorithms for Object Localization
Object localization using sensed data features and corresponding model features is a fundamental problem in machine vision. We reformulate object localization as a least squares p...

The Intrinsic Structure of Optic Flow Incorporating Measurement Duality
The purpose of this article is to define optic flow for scalar and density images without using a priori knowledge other than its defining conservation principle, and to incorpo...

Rational Filters for Passive Depth from Defocus
A fundamental problem in depth from defocus is the measurement of relative defocus between images. The performance of previously proposed focus operators are inevitably sensitive t...
