"The Center for Telecommunications Education and Research (CTER) at the University of Alabama at Birmingham is presently involved with research in the area of telepathology system architectures and performance. The purpose of the research is to aid physicians in the diagnoses of disease in microscopic tissue specimens. If the image acquisition component of the telepathology system had the potential to render preliminary diagnostic results in certain cases, this would allow the physician to make a complete diagnosis in a shorter period of time. This approach to telepathology is a primary motivation behind the Linux DSP Shell (Bonner, 1999). This type of research requires a robust, stable platform that allows for real-time image acquisition and complex processing. The nature of the telemedicine application also requires the use of subsystems that do not adversely affect overall system performance. For these reasons, as well as for economic considerations, Linux was the environment of choice. However, image processing solutions for the Linux environment have been limited. This was the case until Wes Hosking et al., (Hosking 1998), ported the Dipix Vision Library (XVL) to Linux. This made it possible to pursue a real-time image processing system for the Linux environment."

"Although the concept for this project arose from a sponsored research project related to telemedicine, the development of the prototype DSP Shell system was initiated as part of an author's Senior Design sequence in the UAB Dept. of Electrical and Computer Engineering. As such, the student's design objectives were parallel to that of the project. By combining results from development of an application platform for Linux with reporting on the culmination of the undergraduate experience in Engineering, we hope to expose interested readers to both the process of technical education and the excellent development properties of the Linux environment."
