#define IsValidFeature (   Fid)    ((Fid) < MAX_FEATURE_ID)

all feature matchers that are to be used with the high level classifier must support the following interface. The names will, of course, be unique for each different matcher. Note also that FEATURE_STRUCT is a data structure that is defined specifically for each feature extractor/matcher pair.

Typedef Documentation


a CERTAINTY is an indication of the degree of confidence of the classifier. Higher is better. 0 means the match is as good as the mean of the matches seen in training. -1 means the match was one standard deviation worse than the training matches, etc.

Definition at line 62 of file matchdefs.h.

a CLASS_ID is the ascii character to be associated with a class

Definition at line 35 of file matchdefs.h.

typedef uinT8 FEATURE_ID

FEATURE_ID is the index of a feature within a character description The feature id ranges from 0 to N-1 where N is the number of features in a character description.

Definition at line 47 of file matchdefs.h.

typedef inT16 PROTO_ID

a PROTO_ID is the index of a prototype within it's class. Valid proto id's are 0 to N-1 where N is the number of prototypes that make up the class.

Definition at line 41 of file matchdefs.h.

typedef FLOAT32 RATING

a RATING is the match rating returned by a classifier. Higher is better.

Definition at line 56 of file matchdefs.h.


define a data structure for holding an array of match results
