Hello This is to announce Fredo-Editor, a frequency domain image editor. Website: http://fredo-editor.github.io/ Source: https://github.com/fredo-editor/FreDo Installation: http://fredo-editor.github.io/install/ Tutorial: http://fredo-editor.github.io/tutorial/ Fredo-Editor (Frequency Domain Editor) is a GUI for editing images in their frequency spectrum. It is intended for academic/research purposes. It's main goal is to help the user understand the Fourier Transform, by seeing it taking effect in real time. It can also be used to remove periodic noise from images as seen here: http://fredo-editor.github.io/gallery/ At this point, only basic square shape modifications are possible. I want to gather feedback to know what features to add. I intend this to be a small. handy tool for researchers, students and teachers to explore, visualize and understand the Fourier Transform and frequency domain filtering. Any comments and criticisms are welcome. *Note:* Fredo-Editor is still under development and its features and functionality is subject to change.
