unsigned char

b

[static]

given a byte, count the bits using a compile time generated look up table

Parameters:

b

the byte to count bits. The look up table has an entry for all values of b, where that entry is the number of bits.

Returns:

the number of bits in byte b

ResultType cv::HammingLUT::operator()	(	const unsigned char *	a,
		const unsigned char *	b,
		int	size
	)			const

this will count the bits in a ^ b
