Distance Metric Between 3D Models and 3D Images for Recognition and Classification
(1992-07-01)
Similarity measurements between 3D objects and 2D images are useful for the tasks of object recognition and classification. We distinguish between two types of similarity metrics: metrics computed in image-space (image ...
Optical Flow From 1D Correlation: Application to a Simple Time-To-Crash Detector
(1993-10-01)
In the first part of this paper we show that a new technique exploiting 1D correlation of 2D or even 1D patches between successive frames may be sufficient to compute a satisfactory estimation of the optical flow field. ...
Some Extensions of the K-Means Algorithm for Image Segmentation and Pattern Classification
(1993-01-01)
In this paper we present some extensions to the k-means algorithm for vector quantization that permit its efficient use in image segmentation and pattern classification tasks. It is shown that by introducing state ...
3D Pose from Three Corresponding Points Under Weak-Perspective Projection
(1992-07-01)
Model-based object recognition commonly involves using a minimal set of matched model and image points to compute the pose of the model in image coordinates. Furthermore, recognition systems often rely on the ...
Visual Tracking
(1992-10-01)
A typical robot vision scenario might involve a vehicle moving with an unknown 3D motion (translation and rotation) while taking intensity images of an arbitrary environment. This paper describes the theory and implementation ...
Motivated Action Theory: A Formal Theory of Causal Reasoning
(1991-12-01)
When we reason about change over time, causation provides an implicit preference: we prefer sequences of situations in which one situation leads causally to the next, rather than sequences in which one situation follows ...
Intellectual Property in Computing: (How) Should Software Be Protected? An Industry Perspective
(1992-05-01)
The future of the software industry is today being shaped in the courtroom. Most discussions of intellectual property to date, however, have been frames as debates about how the existing law --- promulgated long before the ...
Systematic Nonlinear Planning
(1991-12-01)
This paper presents a simple, sound, complete, and systematic algorithm for domain independent STRIPS planning. Simplicity is achieved by starting with a ground procedure and then applying a general and independently ...
Localization and Positioning Using Combinations of Model Views
(1992-09-01)
A method for localization and positioning in an indoor environment is presented. The method is based on representing the scene as a set of 2D views and predicting the appearances of novel views by linear combinations ...
Pattern Motion Perception: Feature Tracking or Integration of Component Motions?
(1994-10-01)
A key question regarding primate visual motion perception is whether the motion of 2D patterns is recovered by tracking distinctive localizable features [Lorenceau and Gorea, 1989; Rubin and Hochstein, 1992] or by ...
