Iconic Retrieval by Contents from Databases of Cardiological Sequences
Gianfranco Congiu, Alberto Del Bimbo, Enrico Vicario · 1995
The inherent complexity of retrieval by contents of image sequences imposes the use of appropriate techniques supporting the representation of the contents and the specification of content-oriented queries. A number of such techniques have been proposed in the literature but all of these consider images representing un-deformable rigid shapes. In this paper, the case of time-varying imaged curves is addressed with reference to a database of cineangiographic reports. Qualitative static and dynamic shape descriptors are introduced to provide a symbolic representation of the evolution of deformable shapes, and a language based on Interval Logic is presented which supports the expression of content-oriented queries. A prototype system is described which exploits these indexing and querying languages to support retrieval by contents from a database of cineangiographic reports through visual iconic interaction.
