Window-based parallelarchitectures are considered as target structures for the computation of low and medium level image processingalgorithms. their definition stems from a general reformulation of algorithms, based on local data processing. A methodology for high level global evaluation of such architectures is presented, considering the reachable performances of the structures as main significant parameters.< >
Rank order filters form an important class of low level image operations that have widespread applications in image smoothing, texture analysis, etc. In this paper, we study several ways of computing rank order filter...

the paper concerns computational models and languages for iterative cellular automata for image processing applications. the authors present some formal models, with different computational resources, that can be useful in the solution of certain algorithmic problems. they introduce some concepts such as memory splitting, conditional functions, dynamic neighborhood and supervisor automaton. the models defined lead to a parallel language structure that can express low-level image processingalgorithms in a clear and concise way. the language allows a transparent description of the algorithms and can be easily expandable to reflect the needs of people working in different branches of image processing.< >

this paper proposes a novel approach to program development for highly parallelarchitectures, primarily as far as debugging is concerned. the visual nature of the debugging stage, when dealing with image-processingalgorithms, is heavily supported so that all the relevant information, which is generally either hidden or presented without its logical structures, is made available to programmers. the authors present the modular and portable software system built, in Pavia University, for the PAPIA2 machine.< >

Studies the parallel recognition of 2D-images generated by parallel context-free image grammars. the authors show that the recognition of an n*n image can be done in O(log/sup 2/(n)) time with n/sup 6/ processors. For unambiguous context-free and linear image grammars, they prove that only O(n/sup 3/) is needed. For deterministic parallel image grammars, the recognition can be done in O(log/sup 2/(n)) time by using n/sup 2/ processors.< >

Describes a parallel computing system and a software algorithm for realtime interaction between a human user and a synthesized moving humanlike image or agent. the realistic human-like agent appearing on a display can recognize the palm position and finger motion (finger sign) of the human user, then tracks and gazes at the hand position and changes his/her facial expression in response to the recognized finger sign in realtime. this kind of interactive agent is expected to play an important role in advanced human interfaces. To realize realtime image recognition and image synthesis, a parallel image processing and synthesis system named 'TN-VIT' has been developed.< >
