Recenter calculates the thresholded centroid of an image and then recenters the image.

Parameters
relativeThreshold	float	Relative threshold, expressed as a fraction of the maximum value in the image.	0.1f
typeOfThreshold	int	Type of threshold: 1 = subtract, then set negative values to zero. 2 = set values below the threshold to zero	2
dx	float	X spacing of image grid to be used in computation (m), which need not match grid of input image	propdxy
dy	float	Y spacing of image grid to be used in computation (m), which need not match grid of input image	propdxy
nx	int	X dimension of image grid to be used in computation, which need not match grid of input image	propnxy
ny	int	Y dimension of image grid to be used in computation, which need not match grid of input image	propnxy
Inputs
image	Grid<float>	Input image
Outputs
xc	float	X centroid (m)
yc	float	Y centroid (m)
recenteredimage	Grid<float>	Re-centered image
