Image Deformation Using Moving Least Squares (Schaefer 2006) in Rust

Image Deformation Using Moving Least Squares

Rust implementation of the paper "Image Deformation Using Moving Least Squares", Schaefer 2006.

This repository contains the MLS warping code inside moving-least-squares/, an application to image warping inside moving-least-squaers-image/ as well as a demo with example usage producing the above figure inside the moving-least-squares-demo/ directory. To run the demo:

cd moving-least-squares-demo/
cargo run --release

The optional rayon feature enables parallel iterators for the generation of the warped image.

cargo run --release --features rayon

Here is what using the library looks like:

// Open an image from disk.
let img = image::open("data/woody.jpg")?.into_rgb8();

// Define the source control points.
let controls_src: &[(f32, f32)] = &[
    (20.0, 160.0),
    ...
    (250.0, 369.0),
];

// Define the destination control points.
let controls_dst: &[(f32, f32)] = &[
    (20.0, 250.0),
    ...
    (250.0, 369.0),
];

// Create new warped image.
let warped_img_affine =
    mls_image::reverse_dense(&img, controls_src, controls_dst, mls::deform_affine);
