Subtract background of TILED images using 2DDFT: non-calibrated

Parameters:

Name	#	Type	Description
Number of tiles in x	1	integer	The image consists of this number of equal sized tiles in x dimension.
Number of tiles in y	2	integer	The image consists of this number of equal sized tiles in y dimension.
Largest object size (pixels times number of tiles)	3	real	Size of the object to be passed by the filtering. The pixel size must be multiplied by the number if tiles (in x or y). Cut on of the band pass Butterworth filter.
Calculate absolute values	4	boolean	Calculates absolute value after filtering. Required for intensity measurements on high pass and band pass filtered images.

Description:

Removes patterned background originating from tiling using high pass filtering.
Uses pixel size information to generate filter for background suppression. Optimal for tiled images that are composed of quadrangular frames sized power of 2.
Due to a current limitation in the pipeline parametering, the object size must be entered as the real object size in pixels multiplied by the number if tiles (in x or in y).
Tiled images: the background tiling pattern is efficiently removed by spatial filtering if the recording was performed without overlap and image registration. Provide the number of tiles in x and y direction.
