The apparatus 40 arranged for enabling an object mapping in a multi-dimensional dataset has an input 42 for receiving the multi-dimensional dataset in any suitable form. The core of the apparatus is formed by a processor 44, such as a conventional microprocessor or signal processor, a background storage 48 (typically based on a hard disk) and working memory 46 (typically based on RAM). The background storage 48 can be used for storing the dataset (or parts of it) when not being processed, and for storing operations of the graphic relational application macro and models (when not being executed by the processor). The main memory 46 typically holds the (parts of) the dataset being processed and the instructions of the graphic relational application macro and the models used for processing those parts of the dataset. The apparatus 40 according to the invention comprises computation means 45 arranged to define a set of geometric relations between a set of geometric templates using a geometrical relational application framework macro and means 47 for associating the multi-dimensional graphic objects with the geometric templates. Preferably, means 45 and 47 are operable by a computer program 43, preferably stored in memory 48. An output 49 is used for outputting the result of the mapping. Preferably, the output comprises a result of the associating of the multi-dimensional graphic objects with the geometric templates inter-related by the graphic relational application macro. The invention further relates to a method, a computer program, an image analysis system and an imaging system for an object mapping in a multi-dimensional dataset.
