Band Pass filter Optimization ( IAFilterOptimize )

Parameters:

Name	Short Name	Type	Description
Filter type	type	string	The type of the filter to be optimized. Fill in only the relevant cut on and cut off order parameters to the chosen filter type.
Minimum cut on ω	lmin	real	Cut on and cut off ω will be equal or larger than this value.
Maximum cut off ω	lmax	real	Cut on and cut off ω will be equal or smaller than this value.
Cut on order minimum	ordonmin	real	Order of Butterworth filter
Cut on order maximum	ordonmax	real	Order of Butterworth filter
Cut off order minimum	ordoffmin	real	Order of Butterworth filter
Cut off order maximum	ordoffmax	real	Order of Butterworth filter
Spatial freq. (ω) unit	units	string	Sets the units of the above given ω values.
Filter normalization	normalization	string	Normalizes filter coefficients to keep an integral of 1 for the 1D or 2D filter function
Test ROI for attenuation	roi1	integer	Reads intensities from this ROI for the test
Test ROI for transmission	roi2	integer	Reads intensities from this ROI for the test
Number of baseline frames	baseline	integer	The image series consists of the given number of baseline frames followed by the given number of treated frames. This can be repeated any time in this order with the same number of frames.
Number of treatment frames	treatment	integer	The image series consists of the given number of baseline frames followed by the given number of treated frames. This can be repeated any time in this order with the same number of frames.
Direction of change in transmission ROI	direction	string	Whether to look for an increasing or a decreasing signal
Weight on signal to noise ratio	snrweight	real	Weight factor for signal to noise ratio component of the optimization (1-z factor between transmitted and attenuated signals)
Preserve edges	edges	boolean	Performs mirrored tiling to prevent edge artifacts. Slows down processing by 4x.
Enlarge paper	enlarge	boolean	Enlarges image by mirrored tiling to quadrangular. Prevents edge artifacts and distortions from non-quadrangular images.
Enlarge to 2^	enlargeto	integer	Size of image during filtering as power of 2.
Leave only phase	phase	boolean	Sets complex amplitudes in Fourier space to 1 keeping their original arc.
Absolute	absolute	boolean	Calculates absolute value after filtering. Required for intensity measurements on high pass and band pass filtered images.
Protect MASK	protectmask	boolean	Fills up masked areas and undetermined pixel values with zeros before processing. Required for masked images.
