Member Function Documentation

static double jafar::correl::Zncc::compute	(	image::Image const &	im1,
		image::Image const &	im2,
		float const *	weightMatrix = NULL
	)		[static]

This function computes the ZNCC between two images of the same depth in two regions of interest that can be of different size if on the border of theimage, and can apply a spatially distributed weight.

It ignores pixels with extremum value (eg 0 and 255 for char), and ignores parts outside of images, but requires at least half of pixels not ignored to return non 0.

Parameters:

im1	the second image ; the roi can be set (with Image::setROI)
im2	the second image ; the roi can be set (with Image::setROI) and must have the same size than the first one
weightMatrix	the weight matrix that must have the same size than the regions of interest ; if NULL not used

Returns:

ZNCC correlation score between 0 and 1

static double jafar::correl::Zncc::exploreRotation	(	image::Image const *	im1,
		image::Image const *	im2,
		int	rotationStep
	)		[static]

This function return the best ZNCC between two images, the second images get rotated.

Parameters:

im1	the first image ; the roi can be set (with set_roi(CvRect))
im2	the second image ; the roi can be set (with set_roi(CvRect)) and must have the same size than the first one
rotationStep	the step used for the applied rotation
