sr_signature

$ \bigcirc$Name


sr_signature Compute the signature of a shape (density on rings)




$ \bigcirc$Command Synopsis


sr_signature [-n n] [-a base] in out



-n n : number of parameters (default: 20)

-a base : initial set of parameters (Fimage)

in : input shape (Fcurves)

out : final set of parameters




$ \bigcirc$Function Summary


Fimage sr_signature (in , n , base )

Fcurves in ;

int *n ;

Fimage base ;




$ \bigcirc$Description


This module computes rough rotation-invariant parameters from the input shape, which allow to compare quickly two normalized shapes. These parameters measure the density of the shape on increasing rings centered on its barycenter. They are added as a new row to the Fimage base (if it exists) or returned as a new Fimage.
