Function Documentation

FLGR_Golay* flgr2d_create_golay	(	char *	letter,
		FLGR_Type	type,
		FLGR_Connexity	connexity
	)

Set a golay letter in a neighborhood definition
Golay element could be : "L", "M", "C", "D", "E", "F", "F2", "F3", "H", "I"

Element usefull for hit or miss :

• "C" : erosion
• "E" : foreground prunning
• "I" : remove isolated points
• "F" : Y junction are removed

Element signification for Thinning :

• "L" : foreground skeleton
• "M" : foreground skeleton with many ramifications
• "D" : foreground skeleton with many ramifications and gaps

Element signification for Thickening :

• "L" : background skeleton
• "M" : background skeleton with many ramifications
• "D" : background skeleton with many ramifications and gaps

Values set inside the neighborhood are :

• 0 : not tested
• 1 : background
• 2 : foreground

Parameters:

	letter	: a string for golay letter
	connexity	: connexity of SE (6 or 8)
	type	: type of SE

Returns:

FLGR_Golay
