# Image Deformation Using Moving Least Squares

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

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:

```sh

cd moving-least-squares-demo/

cargo run --release

```

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

```sh

cargo run --release --features rayon

```

Here is what using the library looks like:

```rust

// 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);

```
