Using an Artifici al Visual System

An Artif ic ial Visual System ( AVS ) has been deve l oped to simplify three dimensiona l microscope image~ f o r presentation and man ipul ation l n an interactive compu ter g raphics s ystem. The AVS consi sts o f several se ts of spatial fil t e rs t ha t decompose an image along three differ ent mea s ureme nt con tinua. A recombination algorithm processes the filter ou tputs to detect ob j ects, to eliminate noise, and to map the detected object s i nto po i nts in a multidimensional featu re space . Re cent discoveries regarding the geometry of the p oi n ts i n t he featur e space are descri bed . One r ecent r esult simp lifies the AVS by decreas i ng the numbe r of filters required t o obta i n the same measuremen ts. Not onl y are accurate measurements possible, but certain image distortions can be modelled and counteracted in t he feature s pace .
