Segmentation examples

The following figures shows a MRT image of the upper part of a human head. For visualisation the intensities of all voxels are project onto the three main planes of the cartesian three-dimensional coordinate space. The data set consists of 217x181x181 Voxel and 256 gray levels. It was generated by brainweb:

In the following images you can see some slices (parallel to the XZ-Plane) of the voxel image (original and segmentation result). In the first column the orignal slice through the original voxel image is displayed. The next two columns show slices of the segmentation result. The 3D-CSC computes real three-dimensional regions. The algorithm does not a segmentation in layers.
