Name

ramp - remove linear trend from a 2D image

Usage

output = ramp(image)

Input

image:: 2D input image

Output

output:: 2D output image from which a 2D plane was subtracted

Description

Parameters a, b, c of a fit of a 2D plane f(x,y) = a*x + b*y + c to input(x,y,) are calculated using an explicit least square solution and te plane is subtracted forming output(x,y) = input(x,y)
