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 and 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
