Function Documentation

bool ciIsEqual	(	char	a,
		char	b
	)

Case insensitive character comparison.

This predicate returns true if a and b are equal up to case.

Returns:

predicate value.

		bool	binary,
		bool	fp,
		int *	numKeypoints,
		vector< double > *	keyValues,
		bool	outGood
	)

Insert descriptor into stream.

The function writes a descriptor in ASCII/binary format and in integer/floating point format into the stream.

Parameters:

	os	output stream.
	descr_pt	descriptor (floating point)
	binary	write binary descriptor?
	fp	write floating point data?

string removeExtension	(	string	name,
		string	ext
	)

Case insensitive extension removal.

The function returns name with the suffix $a ext removed. The suffix is matched case-insensitve.

Returns:

name without ext.

Added new variable and argument flag to indicate to read from pixel_t array instead of file By Xinghao Pan on 14 Aug 08

Start of code modified by Xinghao Pan on 14 Apr 2008 to support the passing of pixel_t arrays directly instead of using files

End of code modified by Xinghao Pan on 14 Apr 2008 to support the passing of pixel_t arrays directly instead of using files

Start of code added by Xinghao Pan on 20 Feb 2008 Facilitate record of gaussian space

End of code added by Xinghao Pan on 20 Feb 2008 Facilitate record of gaussian space

Code change by Xinghao Pan on 17 Jul 08, 0121h Original version throws exception when unable to write to file Causes problem when user has no write permissions to outputfilename path Instead, simply print error code and do not write output
