◆ normxcorr2()

def helpers.normxcorr2	(	template,
		image,
		mode = `"full"`
	)

Input arrays should be floating point numbers.
:param template: N-D array, of template or filter you are using for cross-correlation.
Must be less or equal dimensions to image.
Length of each dimension must be less than length of image.
:param image: N-D array
:param mode: Options, "full", "valid", "same"
full (Default): The output of fftconvolve is the full discrete linear convolution of the inputs.
Output size will be image size + 1/2 template size in each dimension.
valid: The output consists only of those elements that do not rely on the zero-padding.
same: The output is the same size as image, centered with respect to the 'full' output.
:return: N-D array of same dimensions as image. Size depends on mode parameter.
