Function Documentation

double log_probability_no_spot	(	const CVD::SubImage< float > &	im,
		double	variance
	)		[inline]

Find the log probability of an image patch, assuming zero mean and the given variance, and no spot present.

See also log_probability_spot()

Parameters:

im	Image
variance	variance

Returns:

The log probability

    return logprob_part/(2*variance) - im.size().area() * log(2*M_PI*variance)/2;
