Alignment by Maximization of Mutual Information
(1995-03-01)
A new information-theoretic approach is presented for finding the pose of an object in an image. The technique does not require information about the surface properties of the object, besides its shape, and is robust ...
Parameter Estimation in Chaotic Systems
(1995-04-01)
This report examines how to estimate the parameters of a chaotic system given noisy observations of the state behavior of the system. Investigating parameter estimation for chaotic systems is interesting because of ...
Contact Sensing: A Sequential Decision Approach to Sensing Manipulation Contact
(1995-05-01)
This paper describes a new statistical, model-based approach to building a contact state observer. The observer uses measurements of the contact force and position, and prior information about the task encoded in a ...
Asymptotically Zero Energy Computing Using Split-Level Charge Recovery Logic
(1994-06-01)
The dynamic power requirement of CMOS circuits is rapidly becoming a major concern in the design of personal information systems and large computers. In this work we present a number of new CMOS logic families, Charge ...
Passive Dynamics in the Control of Gymnastic Maneuvers
(1995-03-01)
The control of aerial gymnastic maneuvers is challenging because these maneuvers frequently involve complex rotational motion and because the performer has limited control of the maneuver during flight. A performer can ...
Embodiment and Manipulation Learning Process for a Humanoid Hand
(1995-05-01)
Babies are born with simple manipulation capabilities such as reflexes to perceived stimuli. Initial discoveries by babies are accidental until they become coordinated and curious enough to actively investigate their ...
An Analysis of the Effect of Gaussian Error in Object Recognition
(1994-02-01)
Object recognition is complicated by clutter, occlusion, and sensor error. Since pose hypotheses are based on image feature locations, these effects can lead to false negatives and positives. In a typical recognition ...
Sequential Optimal Recovery: A Paradigm for Active Learning
(1995-05-12)
In most classical frameworks for learning from examples, it is assumed that examples are randomly drawn and presented to the learner. In this paper, we consider the possibility of a more active learner who is allowed ...
Reciprocal Interactions Between Motion and Form Perception
(1995-04-21)
The processes underlying the perceptual analysis of visual form are believed to have minimal interaction with those subserving the perception of visual motion (Livingstone and Hubel, 1987; Victor and Conte, 1990). ...
Fast Object Recognition in Noisy Images Using Simulated Annealing
(1995-01-25)
A fast simulated annealing algorithm is developed for automatic object recognition. The normalized correlation coefficient is used as a measure of the match between a hypothesized object and an image. Templates are ...
