Crate oidn 

Rust bindings to Intel’s Open Image Denoise.

Open Image Denoise documentation can be found here.

Example

The crate provides a lightweight wrapper over the Open Image Denoise library, along with raw C bindings exposed under oidn::sys. Below is an example of using the the RayTracing filter to denoise an image.

// Load scene, render image, etc.

let input_img: Vec<f32> = // A float3 RGB image produced by your renderer.
let mut filter_output = vec![0.0f32; input_img.len()];

let device = oidn::Device::new().expect("failed to create an OIDN device");
oidn::RayTracing::try_new(&device)
    .expect("Failed to create the filter")
    // Optionally add float3 normal and albedo buffers as well.
    .srgb(true)
    .image_dimensions(input.width() as usize, input.height() as usize)
    .filter(&input_img[..], &mut filter_output[..])
    .expect("Filter config error!");

// Save out or display filter_output image.
