An implementation of the VIVA visual language on the NeXT computer

This paper describes a visual programming environment for image processing implemented on the NeXT computer. It is based upon the visual language VIVA (Visualization of Vision Algorithms). Iconic representations of image processing operations are placed and connected together into dataflow networks in a workbench window. The workbench includes a set of editing tools which facilitate algorithm development. Operator parameters can be interactively adjusted as algorithms are repeatedly executed to produce an optimized output. The optimized algorithm can then be saved and reused in subsequent programs
