SuperImage is an Android application that uses AI to upscale low-resolution images, targeting users who want to improve the quality of their pictures on mobile devices. It leverages Real-ESRGAN models and on-device GPU processing for efficient upscaling.

How It Works

The application employs a neural network-based approach using the Real-ESRGAN model. Images are processed in tiles on the device's GPU, utilizing the MNN deep learning framework. This tiled processing and on-device execution are advantageous for mobile performance and privacy, avoiding cloud dependencies.

Quick Start & Requirements

• Install via APK from the Releases Section.
• Requires Android 7 or above.
• Requires Vulkan or OpenCL support on the device GPU.
• Setup is immediate upon APK installation.

Highlighted Details

• Achieves 4x upscaling (1920x1080 to 3840x2160) in approximately 3 minutes on a Qualcomm Snapdragon 855 with Vulkan.
• Supports 16x upscaling, with a "drawing" mode significantly reducing processing time for such content.
• Built using the MNN deep learning framework.

Maintenance & Community

• Community support and discussions are available via a Telegram group.
• Feedback and bug reports can be submitted via GitHub Issues; pull requests are accepted.

Licensing & Compatibility

• Licensed under GNU General Public License v3.0 (GPL-3.0).
• The GPL-3.0 license is copyleft, requiring derivative works to also be open-sourced under the same license, which may restrict commercial or closed-source integration.

Limitations & Caveats

The project is currently Android-only, with planned future support for web and desktop versions. Batch processing is also listed as a future enhancement.
