FFT_Helper

A small Action Bar to help exploring FFT/Frequency domain images in FIJI.

Feedback welcome!

Installation

Unzip the ActionBar .zip into the plugins folder of your FIJI installation.

Usage

Run the ActionBarbar through Plugins › ActionBar › FFT Helper or from the command finder.

ActionBar_snapshot

Open an image then run Forward_FFT. On the FFT Image create regions of interest to exclude. For this draw a ROI (using the selection tools from the Fiji bar), add to the ROI manager (Shortcut: T) then mirror if necessary.

No need to erase anything from the FFT image: when running Reverse_FFT it will automatically create the corresponding image of both the FFT excluding the selection or only including the selection.

Demo

The sample image below can be found in File › Open Samples › Comparing Lengths. The sample image was converted to 8-Bit then inverted before running the Forward_FFT. Demo1

Running Reverse_FFT from the toolbar will output the 2 images below: Demo2

To do

Add the ability to batch process files with the created mask.
