Description:
Thinness Ratio Filter Pair Optimization.
The Low Frequency band pass (LBP) and High Frequency band pass (HBP) filters are searched between the given cut on and cut off range. These filters are Butterworth band pass filters, and for simplicity all cut ons and cut offs have the same order which is sought between the "Order minimum" and "Order maximum".
The Thinness Ratio (TR) is calculated within the Test ROI. The basis of optimization is the comparison the TR in the baseline frames and the treatment frames. Given number of treatment frames follow the given number of baseline frames, and t-test is used to compare baseline and treatment TR values. The most significant change to the "Direction of change" is taken as the best filter pair.
Edge artifacts could be avoided by tiling a larger image with the original in a symmetric, thus periodic manner. To protect edges use "Preserve edges" when an image is quadrangular and size of power of 2.
Non-quadrangular images are unevenly filtered in x and y directions, therefore use "Enlarge paper" to tile a larger quadrangular image before filtering.
"Preserve edges" and "Enlarge paper" do not change the size or spatial calibration of the resultant image, the result is obtained by cropping the enlarged image to the original size. Fourier transformation is incompatible with masking (pixels without a real value), therefore the mask has to be filled up with zeros "Protect MASK" before filtering.
