Region-Based Feature Interpretation for Recognizing 3D Models in 2D Images
(1991-06-01)
In model-based vision, there are a huge number of possible ways to match model features to image features. In addition to model shape constraints, there are important match-independent constraints that can efficiently ...
Why are There so Few Female Computer Scientists?
(1991-08-01)
This report examines why women pursue careers in computer science and related fields far less frequently than men do. In 1990, only 13% of PhDs in computer science went to women, and only 7.8% of computer science ...
Robot Motion Vision by Fixation
(1992-09-01)
In many motion-vision scenarios, a camera (mounted on a moving vehicle) takes images of an environment to find the "motion'' and shape. We introduce a direct-method called fixation for solving this motion-vision problem ...
Taming Chaotic Circuits
(1992-09-01)
Control algorithms that exploit chaotic behavior can vastly improve the performance of many practical and useful systems. The program Perfect Moment is built around a collection of such techniques. It autonomously ...
A Vector Signal Processing Approach to Color
(1992-01-01)
Surface (Lambertain) color is a useful visual cue for analyzing material composition of scenes. This thesis adopts a signal processing approach to color vision. It represents color images as fields of 3D vectors, from ...
Using Recurrent Networks for Dimensionality Reduction
(1992-09-01)
This report explores how recurrent neural networks can be exploited for learning high-dimensional mappings. Since recurrent networks are as powerful as Turing machines, an interesting question is how recurrent networks ...
Statistical Object Recognition
(1993-01-01)
Two formulations of model-based object recognition are described. MAP Model Matching evaluates joint hypotheses of match and pose, while Posterior Marginal Pose Estimation evaluates the pose only. Local search in pose ...
Geometry and Photometry in 3D Visual Recognition
(1992-11-01)
The report addresses the problem of visual recognition under two sources of variability: geometric and photometric. The geometric deals with the relation between 3D objects and their views under orthographic and ...
Reconfigurable Architectures for General-Purpose Computing
(1996-09-01)
General-purpose computing devices allow us to (1) customize computation after fabrication and (2) conserve area by reusing expensive active circuitry for different functions in time. We define RP-space, a restricted ...
A Hierarchical Cache Coherent Protocol
(1992-09-01)
As the number of processors in distributed-memory multiprocessors grows, efficiently supporting a shared-memory programming model becomes difficult. We have designed the Protocol for Hierarchical Directories (PHD) to ...
