We present a statistical image-based shape + structure model for Bayesian visual hull reconstruction and 3D structure inference. The 3D shape of a class of objects is represented by sets of contours from silhouette ...
Solutions of learning problems by Empirical Risk Minimization (ERM) need to be consistent, so that they may be predictive. They also need to be well-posed, so that they can be used robustly. We show that a statistical ...
Modeling and predicting co-occurrences of events is a fundamental problem of unsupervised learning. In this contribution we develop a statistical framework for analyzing co-occurrence data in a general setting where ...
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 ...
This memo describes the step by step solution of three problems from different fields of applied mathematics. These problems are solved by typing a series of computer commands for the manipulation of symbolic mathematical ...
This paper describes a hardware system designed to facilitate position and velocity control of a group of eight stepping motors using a PDP-11. The system includes motor driver cards and other interface cards in addition ...

This paper discusses what it would mean to have a psychological model of the language production process: what such a model would have to account for, what it would use as evidence. It outlines and motivates one particular ...
This paper describes a system which automatically generates program documentation. Starting with a plan generated by analyzing the program, the system computes several kinds of summary information about the program. The ...
We describe a method to solve the stereo correspondence using controlled eye (or camera) movements. These eye movements essentially supply additional image frames which can be used to constrain the stereo matching. ...
A brief introduction to use of projecting coordinates for hand-eye position computations. Some standard theorems. Appendix A reproduces parts of Roberts' thesis concerning homogenous coordinated and matching of perspectively ...
In this text, we present two stereo-based head tracking techniques along with a fast 3D model acquisition system. The first tracking technique is a robust implementation of stereo-based head tracking designed for ...
This paper describes a new method for matching, validating, and disambiguating features for stereo vision. It is based on the Marr-Poggio- Grimson stereo matching algorithm which uses zero-crossing contours in ...
We describe a psychophysical investigation of the effects of object complexity and familiarity on the variation of recognition time and recognition accuracy over different views of novel 3D objects. Our findings indicate ...
Tsunoda et al. (2001) recently studied the nature of object representation in monkey inferotemporal cortex using a combination of optical imaging and extracellular recordings. In particular, they examined IT neuron ...
We consider general combinatorial optimization problems that can be formulated as minimizing the weight of a feasible solution wT x over an arbitrary feasible set. For these problems we describe a broad class of corresponding ...

We introduce combinational stochastic logic, an abstraction that generalizes deterministic digital circuit design (based on Boolean logic gates) to the probabilistic setting. We show how this logic can be combined with ...
A short description of LISP functions that have been written for use with the stored picture facility. These functions allow one to display an image of a stored scene on the 340 scope, and produce graphs and histograms of ...

This paper is written for an Area Examination on the three papers: "A Framed PAINTING: The Representation of a Common Sense Knowledge Fragment" by Eugene Charniak, "Reporter: An Intelligent Noticer" by Steve Rosenberg, and ...
This document describes the STRING programming language which has been implemented on the MAC Artificial Group's PDP-6 computer. In the STRING system, all objects--constants, variables, functions and programs--are ...
String manipulation can be made convenient within the *** language by implementing two functions: 1) match [workspace; pattern] and 2) construct {format;pmatch]. In this memo I describe how I think these two functions can ...
