| A two-stage methodology for interactive
segmentation of volume data sets is presented in this paper. In
the first stage (presegmentation) a 3D watershed transformation
is used for segmenting the data in different small regions.
According to the neighboring relationships between this regions a
region adjacency graph (RAG) is constructed. During the second
stage (interactive information extraction), a 3D region growing
algorithm driven by user controlled parameters is applied to the
RAG until a satisfactory segmentation result is achieved. The
presegmentation step greatly reduces the complexity of the
segmentation problem. On account of that, a fast information
extraction is possible in the second stage. In combination with
our realtime volume rendering hardware VIRIM, the response time
of the information extraction stage performed on a medical data
set with 256 x 256 x 128voxels is less than a second. |
