TECHNOLOGY SUMMARY
 
What is this product?
The Signature Classification Development System (SCDS) is a graphical-programming PC application that allows the user to visually program a multi-channel classification system with minimal programming training. User-expandable libraries of routines allow the user to select data formats, signal and image processing, vector and matrix mathematics, template matching, feature extraction, and classification algorithms.

What can it do?
Potential Applications
For classification tasks: Human interpretation of complex images and signals is unreliable and expensive. SCDS can automate the processes that a human expert uses in interpreting data. This product has been used extensively to design programs for automating the interpretation of data from nondestructive evaluation tests, including: ultrasonic, eddy-current, and X-ray inspections.

For processing tasks: The data handling features of the program make it ideal for performing signal or image processing in batch mode on large quantities of data.

SCDS Is New
This program allows a nonspecialist to write a signal or image analysis or classification program. The data representation is reduced to the simplest possible notation. Unlike other graphical programming languages, data types and dimensions are handled automatically and are of no concern to the user. This drastically reduces the complexity of the programming interface.

The algorithms developed using the icons and links on the screen are exportable into "C" code for inclusion into larger systems. In addition, SCDS provides a documentation function that produces a human-readable description of the algorithm developed.

Multichannel data capability, with individual channels possibly being images or signals in the same project, allows the fusion of different sensor technologies into one analysis and classification environment.

What are the benefits?
All functions of the program are user-expandable; the input and output, the signal and image processing, the template matching, math, and the classification libraries have prepackaged routines, but can be supplemented with C source code by the user. The program, written with the user pointing and clicking, is exportable into C source code, and dynamic link libraries (DLLs) are available for inclusion into other software systems.
