double brip_histogram	(	const vil_image_view< T > &	image,

	)

Construct histogram from pixels in the given image.

same as vil_histogram except that it returns the sum of all values in the histogram.

template<class T >

double brip_joint_histogram	(	const vil_image_view< T > &	image1,
		const vil_image_view< T > &	image2,
		vcl_vector< vcl_vector< double > > &	histo,
		double	min,
		double	max,
		unsigned	n_bins
	)

Construct the joint histogram between image1 and image2.

The the values of min, max, and n_bins are used on both images the result is a 2D (n_bins x n_bins) vcl_vector. The sum of all values in the histogram is returned.

values in an image of weights. The sum of all weights used is returned.
