Depix: A PoC for Depixelization

Depix is a proof of concept (PoC) tool designed to recover plaintext from pixelated screenshots. It utilizes a method based on a linear box filter to optimize the process of depixelization. Here are some key features:

• Algorithm Efficiency: The algorithm processes pixelized images, checking for matches against a search image under the assumption of pixel-level text positioning.
• Example Usage: Users can easily run the tool using Python with straightforward command-line instructions, allowing access to functionality like generating pixelated images and testing different averaging methods.
• Documentation and Support: Detailed guides and example usage are provided, helping users understand how to prepare images and run the depixelization process effectively.

Benefits include:

• Enhanced Text Recovery: By leveraging a combination of image processing techniques, users can recover potentially sensitive information that might have been pixelated in screenshots.
• Open Source Contribution: The project encourages implementation and contribution from users interested in developing similar tools or improving existing functionality.

With its roots in academic research, Depix also helps provide a practical solution to challenges posed by pixelization methods commonly used to obscure sensitive data in digital imagery.
