RMBG Crate

This crate provides an easy-to-use interface for removing backgrounds from images, leveraging a machine learning model. It's designed to integrate seamlessly into Rust projects requiring background removal capabilities.

Rust docs: https://docs.rs/rmbg/latest/rmbg/struct.Rmbg.html Crates.io: https://crates.io/crates/rmbg

Features

• Load and apply a machine learning model to remove backgrounds from images.
• Maintains original image dimensions, replacing the background with transparency.
• Preprocess and postprocess images to conform to model requirements.

Getting Started

Prerequisites

Before using the rmbg crate, you need to download the required model.onnx file. This model is a crucial component as it powers the background removal process. You can download it from the following URL:

https://huggingface.co/briaai/RMBG-1.4/blob/main/onnx/model.onnx

Place the downloaded model.onnx file in a known directory within your project.

Installation

Add rmbg to your Cargo.toml file:

[dependencies]
rmbg = { version = "0.1.0", default-features = false }

Note for Library Developers

If you are developing a library that includes rmbg, it is heavily recommended to disable default features to avoid unnecessary bloat. Cargo features are additive, and enabling default features in a library can prevent downstream users from opting out of those features, leading to increased compile times and binary sizes.

Instead, enable the necessary features in your development dependencies as follows:

[dev-dependencies]
rmbg = { version = "0.1.0", features = ["download-binaries"] }

Instruct downstream users to include ort in their dependencies if needed, with the download-binaries feature enabled:

[dependencies]
ort = { version = "...", features = ["download-binaries"] }

Usage

To use the rmbg crate in your project, first, initialize an instance of the Rmbg struct with the path to the model.onnx file. Then, call the remove_background method with an image to process.

Here's a simple example:

use rmbg::Rmbg;
use image::DynamicImage;

fn main() -> anyhow::Result<()> {
    // Load the model
    let rmbg = Rmbg::new("path/to/model.onnx")?;

    // Load an image
    let original_img = image::open("path/to/image.png")?;

    // Remove the background
    let img_without_bg = rmbg.remove_background(&original_img)?;

    // Save or further process `img_without_bg` as needed
    Ok(())
}
