Processing of volumetric data by slice- and process-based streaming
2007
Proceedings of the 5th international conference on Computer graphics, virtual reality, visualisation and interaction in Africa - AFRIGRAPH '07
Preserved Fulltext
In this paper, we advocate slice-based streaming as a possible solution for the memory shortage problem in the case of preprocessing and analysis of volumetric data defined over Cartesian, regular and ...
In our version of streaming, data flows through independent processing units-filters-represented by individual system processes, which store each just a minimal fraction of the whole data set, with a slice ...
Conclusions and future work We proposed the slice-based streaming technique for processing of volumetric data sets. ...
