Function Documentation

float* balance_f32	(	float *	data,
		size_t	size,
		size_t	nb_min,
		size_t	nb_max
	)

normalize a float array

This function operates in-place. It computes the minimum and maximum values of the data, and rescales the data to [0-1], with optionally flattening some extremal pixels.

Parameters:

	data	input/output array
	size	array size
	nb_min,nb_max	number extremal pixels flattened

Returns:

data

normalize an unsigned char array

This function operates in-place. It computes the minimum and maximum values of the data, and rescales the data to [0-UCHAR_MAX], with optionally flattening some extremal pixels.

Parameters:

	data	input/output array
	size	array size
	nb_min,nb_max	number extremal pixels flattened

Returns:
