This paper presents three examples of real-time image processing
applications that were implemented on a data-flow architecture developed
at the ETCA.
Low-level image processing is performed on a regular three-dimensional
network of 1024 custom data-flow processors.
Image features previously extracted in the low-level step are handled by
a two-dimensional network of 12 general purpose processors.
Fast prototyping of real-time image processing applications is achieved
through a programming environment including a complete stream from functional
programming specification to network configuration.
A large class of algorithms can be implemented. Among them we describe
a non-linear filter, a connected component labeling and a colored object
tracking.
