pinnermostmerging

Performs inner-most region merging.

Synopsis

pmostinnermostmerging [-m mask] [rg_in1|-] [rg_in2|-] [rg_out|-]

Description

pinnermostmerging merges regions of input region map rg_in1 to regions of input region map rg_in2 if rg_in2 regions are inner-most rg_in1 regions.

Inner region in rg_in2 is merged with the including region of input region map rg_in that has the longest common boundary points with the inner region other than region 0. Regions of region map rg_in2 that have no neighbor in the region map rg_in1 are not kept in the output region map rg_out.

Inputs

rg_in: a region map.
gr_in: a region map with the regions to be merged.

Outputs

rg_out: a region map.

Result

Returns the number of merged regionß.

Examples

Segments tangram.pan and then merges inner regions:

    pbinarization 96 1e30 tangram.pan a.pan
    plabeling 8 a.pan b.pan
    pfillhole b.pan c.pan
    pdif b.pan c.pan d.pan
    plabeling 8 d.pan e.pan
    pinnermostmerging b.pan e.pan out.pan

C++ prototype

Errc PMostInneMostMerging( const Reg2d &rg_in1, const Reg2d &rg_in2, Reg2d &rg_out );

Version française
