Tool for Pictorial Data Transformations
Abstract
The search in pictorial databases has been based on various approaches, such as the use of histograms describing physical characteristics of raster images or of key words defining the contents of the picture from the semantic point of view. Our approach is based on the structural description, in which objects in the picture (represented by keywords) are linked by relations of various types. In order to perform an efficient search in the picture, it is necessary to have a tool at one's disposal that describes these relations in a formal way. Such a description would allow the user not only to search for a picture with specific properties, but also to perform transformations of the picture description. These transformations may infer some information from existing ones that may lead to an easier search for a specific picture. Another application of these transformations is the transformation of the picture description into standard graphical formats which add flexibility to the system using the approach described. The formalism used for picture description is XML. It is similar to the MPEG-7 structure and semantic description. The pilot system with the features described has been designed, implemented and tested. The generalized concept of the system and relation to other XML-based picture formats (e.g.MPEG-7) could allow the user to perform usability tests of functions of these formats.
