Fingerprints Theorems for Zero-Crossings
(1983-10-01)
We prove that the scale map of the zero-crossings of almost all signals filtered by the second derivative of a gaussian of variable size determines the signal uniquely, up to a constant scaling and a harmonic function. ...
Parts of Recognition
(1983-12-01)
A complete theory of object recognition is an impossibility ??t simply because of the multiplicity of visual cues we exploit in elegant coordination to identify an object, but primarily because recognition involves ...
Determining Attitude of Object from Needle Map Using Extended Gaussian Image
(1983-04-01)
An extended Gaussian image (EGI) is constructed by mapping the surface normals of an object onto the Gussian sphere. The attitude of an object is greatly constrained by the global distribution of EGI mass over the ...
Semantic Support for Work in Organizations
(1983-04-01)
Present day computer systems cannot implement much of the work carried out in organizations such as: planning, decision making, analysis, and dealing with unanticipated situations. Such organizational activities have ...
Wrist-Partitioned Inverse Kinematic Accelerations and Manipulator Dynamics
(1983-04-01)
An efficient algorithm is presented for the calculation of the inverse kinematic accelerations for a 6 degree-of-freedom manipulator with a spherical wrist. The inverse kinematic calculation is shown to work synergistically ...
Understanding Text through Summarization and Analogy
(1983-04-01)
Understanding a text exactly in the way that the Text Producer meant the text to be understood is highly unlikely unless the text interpretation process is constrained. Specific understanding-directing criteria are ...
Representing and Reasoning About Change in Geologic Interpretation
(1983-12-01)
Geologic interpretation is the task of inferring a sequence of events to explain how a given geologic region could have been formed. This report describes the design and implementation of one part of a geologic interpretation ...
Using Structural and Functional Information in Diagnostic Design
(1983-06-01)
We wish to design a diagnostic for a device from knowledge of its structure and function. the diagnostic should achieve both coverage of the faults that can occur in the device, and should strive to achieve specificity ...
Structure from Stereo and Motion
(1983-09-01)
Stereopsis and motion parallax are two methods for recovering three dimensional shape. Theoretical analyses of each method show that neither alone can recover rigid 3D shapes correctly unless other information, such ...
Naive Problem Solving and Naive Mathematics
(MIT Artificial Intelligence Laboratory, 1983-06)
AI problem solvers have almost always been given a complete and correct axiomatization of their problem domain and of the operators available to change it. Here I discuss a paradigm for problem solving in which the problem ...
