- The theoretical basis for the popular FSL BET package for brain extraction from neuroimaging data, with the following basic processing steps:
- Binarization of the image based on a threshold estimated from the histogram
- Determination of centre of gravity of the binary image and of the radius of a sphere with a volume equivalent to the number of above-threshold voxels
- Initialization of a tesselated surface of a sphere with half that radius
- Surface growing until the enclosed volume reaches the size of the full sphere and is topologically correct
