Part-of-Math Tagging and Applications

June 28, 2017
Author(s)
Abdou S. Youssef
Much of the mathematical literature, old and new, is online and mostly in natural-language form. Therefore, math content processing presents some of the same challenges faced in natural language processing (NLP), such as math disambiguation and math

Technical Aspects of the Digital Library of Mathematical Functions

May 1, 2003
Author(s)
Bruce R. Miller, Abdou S. Youssef
The NIST Digital Library of Mathematical Functions (DLMF) Project, begun in 1997, is preparing a handbook and Web site intended for wide communities of users. The contents are primarily mathematical formulas, graphs, methods of computation, references, and

Surface-Fitting Modeling of Images: Theory and Applications

October 8, 1999
Author(s)
Anastase Nakassis, Abdou S. Youssef
Image processing is a very active area with many applications. Many tasks in image processing are highly complicated, and the quality of the software and hardware systems that perform those tasks has proved to be very difficult to measure. One useful

Parallel Algorithms for Entropy-Coding Techniques

December 1, 1998
Author(s)
Abdou S. Youssef
With the explosion of imaging applications, and due to the massive amounts of imagery data, data compression is essential. Lossless compression also called entropy coding, is of special importance because not only it serves as a stand-alone system for

Moment-Preserving Modeling With Image Applications

July 6, 1998
Author(s)
Anastase Nakassis, Abdou S. Youssef
Linear least-square modeling is a powerful modeling approach. Optimal piece-wise constant modeling is an important special case. In this paper we will develop a piece-wise constant modeling method that preserves the regional means and regional first
