Similarity engine for content-based retrieval of images

摘要: A system and method for content-based search retrieval of visual objects. base information (VIR) engine utilizes a set universal primitives to operate on the An extensible VIR allows custom, modular be defined registered. custom primitive addresses domain specific problems can utilize any image understanding technique. Object attributes extracted over entire or only portion object. schema is as collection primitives. implies features processed corresponding feature vector used similarity scoring. registration interface registers facilitates storing an analysis function comparison table. heterogeneous objects analyzed by different schemas compared if at least one in common between schemas. threshold-based utilized improve performance engine. distance two vectors computed processes so generate score.
