Detailed Description

A contour stencil set $\Sigma$ .

A stencil set is a collection of contour stencils. This is represented as an array ssetstruct::Stencil of type stencilentry. For computational efficiency, an array of quantized stencil vectors stencilqvec is also stored in ssetstruct::StencilTable. The locations of the cells are stored in stencilsetcell::Cell. The point spread function (PSF) to model the sampling of the input image is specified by ssetstruct::Psf.

ssetstruct is the definition of sset, which is encapsulated by forward declaration in sset.h.

Stencil sets are managed with the following functions:

NewStencilSet(): create a new sset
FreeStencilSet(): free an sset
AddStencil(): add a stencil to an sset
GetNumStencils(): get the number of stencils in the set
GetPsf(): get the PSF function pointer
GetPsfParam(): get the PSF parameters PsfParam
GetPsfRadius(): get the PSF radius
