$ \bigcirc$Name


km_createdict_ai Encode a list of curves into an affine-invariant dictionnary




$ \bigcirc$Command Synopsis


km_createdict_ai [-F FNorm] [-N NNorm] list_curves dict



-F FNorm : length factor - default 2.0

-N NNorm : number of points per code - default 9

list_curves : input list of curves (Flists)

dict : output dictionary (Flists)




$ \bigcirc$Function Summary


void km_createdict_ai (FNorm , NNorm , list_curves , dict )

float *FNorm ;

Flists list_curves ;

Flists dict ;




$ \bigcirc$Description


This module computes the affine invariant dictionary of a list of curves. This list is typically the result of the module ll_boundaries followed by gass (see KM_DEMO for an example), which yields the smoothed maximal meaningful level lines of an image. For each line in the list, the module km_codecurve_ai computes codes which are added to the dictionary.


The result is stored in an Flists structure.
