Abstract
The ImageTcl multimedia development system is a new Tcl/Tk-based
development environment specifically targeting development of
high-performance multimedia data analysis algorithms. Multimedia
algorithm development is complicated by large volumes of data, complex
file formats, compression and decompression, and temporal
synchronization. Testing algorithms requires elaborate user
interfaces which can display intermediate and result images, play
audio, and adjust parameters. ImageTcl uses the features of the
Tcl/Tk environment as a base on which to build a system that
significantly aids this process. This paper describes the ImageTcl
approach to algorithm development and describes several applications
of ImageTcl in the Dartmouth Experimental Visualization Laboratory
(DEVLAB).
