Binary visualization

Basic implementation of a binary file visualization algorithm. The idea is to generate a visual representation of a binary file, in order to have a quick overview of its content.

How it works

Here is the explanation of the main.rs file.

We get the raw byte data from a file :

let slice = load_file(file_path);

Then calculate a map (of 256x256 pixels) using slice parcour with a window size of 2 bytes :

let mut map = Map256::zeros();

generate_visualization(&slice, &mut map);

Finally, we generate an RGB image from the map and save it :

let img: RgbImage = map_to_image(&map);

img.save(&args.output).unwrap();

Output example (using rust exec as input) :

# run locally from the root of the project
cargo run -- -p ./target/debug/bvtool

Dataset

WIP

Actually I'm working on creating a large and diverse dataset of binary files representations. It aims to be used for training a neural network to recognize the type of file from its visual representation or other applications.
