Project 13: Extraction of a volume from a 3-D data set
Input: a 3-D data set, for example an MR brain.
Operation: given a seed point generated manually, and a criteria defining an 'edge' for example a voxel that must have values between two limits, grow the region in 3-D to extract the selected object. [Suggestion- start in 2D and then extend to 3D. The connection should be on the basis on likelihood that the neighbouring voxels can be linked to the target voxel (e.g. by building up a linked list/ tree). Manual editing could be added.
Output: data set viewable with 3D viewing package for example 3Dviewnix
Remarks: Difficulty reasonably easy.
