# SuperImage

**Sharpen your low-resolution pictures with the power of AI upscaling**



SuperImage is a neural network based image upscaling application for Android built with the [MNN deep learning framework](https://github.com/alibaba/MNN) and [Real-ESRGAN](https://github.com/xinntao/Real-ESRGAN).



The input image is processed in tiles on the device GPU, using a pre-trained Real-ESRGAN model. The tiles are then merged into the final high-resolution image. This application requires Vulkan or OpenCL support and Android 7 or above





Or get the latest APK from the [Releases Section](https://github.com/Lucchetto/SuperImage/releases/latest).
