This is a Rust library that implements content aware image resizing, also known as seam carving. Seam carving resizes an image so it keeps looking natural, instead of squashing or stretching everything evenly, it removes or adds thin paths of pixels that matter least to the image's content. That means you can shrink a photo's width without warping a face or a building inside it. The README for this project is quite sparse. It does not describe an API, list functions, or explain how to install and use the library in code. What it does include is a link to a web demo where you can try the resizing yourself, plus a short video preview hosted on GitHub showing the effect in action. The project's task list gives a sense of where it is headed. The author is considering adding a rayon feature, which would let the resizing work run across multiple processor cores at once for speed, though they note they are not certain it would actually be faster. Other planned items are benchmark tests to measure performance, and an object retention mask, a way to mark parts of an image that should be protected from removal during resizing. For background on the technique itself, the README links to three resources: the Wikipedia page on seam carving, the original 2007 academic paper that introduced the method, and a 2009 paper on doing it in real time. These are useful if you want to understand the underlying algorithm rather than just use the code. Because so little is documented beyond the demo link and the resources, anyone wanting to use this as a library in their own Rust project would likely need to read the source code directly to learn its functions and how to call them.
