Convert a raster image to graph representation
Each foreground voxel is represented by a node in the output graph. Optionally, only border voxels are used. Optionally, 26-adjacent voxels are connected by arcs. Voxels of grey value '0' are assumed to be background voxels.

Convert a raster image to graph representation.
src | input image (any repn) | |
dest | output graph | |
xmin | voxels with values below 'xmin' are assumed to be background. | |
xmax | voxels with values above 'xmax' are assumed to be background. If both xmin and xmax equal zero then these thresholds are ignored. | |
link | if 'TRUE', then 26-adjacent voxels are linked by an arc. | |
border | if 'TRUE', convert only border voxels. |
