Overview

The Butterworth filter offers a more robust method for applying spatial frequency filters to images compared to traditional FFT/IFFT-based methods. Filters with sharp cutoffs can often lead to the Gibbs phenomenon, where undesirable ringing artifacts appear near edges in the image. This issue is particularly problematic in applications such as EEG experiments (particularly low/mid visual ones that affect P100 amplitudes in the visual cortex) and other scenarios involving low-frequency signals.

Usage

rust cargo add butter2d

```rust use image::{GrayImage, open}; use butter2d::butterworth;

fn main() { let img = open("path/to/your/image.png").expect("Failed to open image").toluma8(); let cutofffrequencyratio = 0.1; let highpass = true; let order = 2.0; let squaredbutterworth = false; let npad = 0; let filteredimg = butterworth( &img, cutofffrequencyratio, highpass, order, squaredbutterworth, npad ); filteredimg.save("path/to/save/filteredimage.png").expect("Failed to save filtered image"); } ```
