Function Documentation

int arActivatePatt

(

int

pat_no

)

activate a pattern on the recognition procedure.

Activate a pattern to be check during the template matching operation.

Parameters:

patt_no

number of pattern to activate

Returns:

return 1 in success, -1 if error

Definition at line 126 of file arGetCode.c.

int arDeactivatePatt

(

int

pat_no

)

desactivate a pattern on the recognition procedure.

Desactivate a pattern for not be check during the template matching operation.

Parameters:

patt_no

number of pattern to desactivate

Returns:

return 1 in success, -1 if error

Definition at line 135 of file arGetCode.c.

int arFreePatt

(

int

patt_no

)

int arLoadPatt

(

const char *

filename

)

load markers description from a file

load the bitmap pattern specified in the file filename into the pattern matching array for later use by the marker detection routines.

Parameters:

filename

name of the file containing the pattern bitmap to be loaded

Returns:

the identity number of the pattern loaded or –1 if the pattern load failed.
