Detailed Description

Pairwise model representation.

Flat 2d objects with pairwise these objects store info as a series of pgh's. A representation of a 2d model. this is a list of PGHs, one created for each line in the original model. also included is the original line information, primarily for rendering purposes.

OK a real object is a set of histograms which describe a set of real lines. That's what this class is for. Eg. pgh_2dobject my_dinoraur_template. Use it basically by doing the following:

    pgh_2dobject  my_dino_template;
    my_dino_template.createFromLines( set_of_lines ); 
    my_dino_template.setName("Arthur_the_stegosaurus");

double mimas::pgh_2dobject::canny_sigma

models can be formed from images. see canny_tool.h

in this case edge strings must be extracted first. the following parameters specify the parameters which are passed to the canny detector for this first step.
