This article describes the Multimission VICAR Planner (MVP): an AI planning system which uses knowledge about image processing steps and their requirements to construct executable image processing scripts to support high-level science requests made to the Jet Propulsion Laboratory (JPL) Multimission Image Processing Subsystem (MIPS). This article describes(More)
This paper describes the use of AI planning techniques to represent scientific, image processing, and software tool knowledge to automate knowledge discovery and data mining (e.g., science data analysis) of large image databases. In particular, we describe two fielded systems. TheMultimission VICAR Planner (MVP) which has been deployed for 2 years and is(More)
[1] The twin Mars Exploration Rovers (MER) delivered an unprecedented array of image sensors to the Mars surface. These cameras were essential for operations, science, and public engagement. The Multimission Image Processing Laboratory (MIPL) at the Jet Propulsion Laboratory was responsible for the first-order processing of all of the images returned by(More)
During the period of development prior to the January, 2004 landing of the Mars Exploration Rover (MER) project's twin robotic vehicles on Mars, mission operations personnel recognized the need for timely generation and delivery of camera image products for rover traverse planning purposes. The task was assigned to the Multimission Image Processing(More)
Ashwin R. Vasavada California Institute of Technology Geological and Planetary Sciences Mail Stop 170-25 Pasadena, California 91125 Abstract. The solid-state imaging subsystem (SSI) on the National Aeronautics and Space Administration’s (NASA’s) Galileo Jupiter orbiter spacecraft has successfully completed its 2-yr primary mission exploring the Jovian(More)
One important approach to enhancing software re-use is through the creation of large-scale software libraries. By modularizing functionality, many complex specialized applications can be built up from smaller reusable general purpose libraries. Consequently, many large software libraries have been formed for applications such as image processing and data(More)
In recent times, improvements in imaging technology have made available an incredible array of dormation in image format. While powerful and sophisticated image processing software tools are available to prepare and analyze the data, these tools are complex and cumbersome, requiring significant expertise to properly operate. Thus, in order to extract (e.g.,(More)
The pharmakokinetics of propylthiouracil was evaluated in 9 elderly patients and compared to previous results from 6 younger subjects. By giving the drug both by the intravenous and oral route of administration it was possible to estimate the rate and extent of bioavailability. The various kinetic parameters were calculated according to a two-compartment(More)
