Function

Provides a dialog-based interface for setting up an annular band-pass filter. This can be used for filtering single images, but is perhaps most useful for rapidly processing multiple images using a fixed FFT mask.

Comments

Requires that the images to be processed are either 2^n x 2^n in size or have a region of interest present with those dimensions. The previous version (v1.0) used a fast blurr function to smooth the annular mask. This caused FFT artefacts for very small radii. This has been replaced with a function which adds gaussian shaped edges to the mask directly.

System Requirements

Should be compatible with all recent versions of DigitalMicrograph.
