The task of recovering a high resolution (HR) image from its low resolution counterpart is commonly referred to as Single Image Super Resolution (SISR).
The model used here is ESRGAN (ESRGAN: Enhanced Super-Resolution Generative Adversarial Networks). The TFLite model is converted from this implementation hosted on TF Hub. Demo images are from DIV2K dataset.
This sample automatically downloads TFLite JAR files and uses TFLite C API through Android NDK.
- Android Studio 3.2 (installed on a Linux, Mac or Windows machine)
- An Android device, or an Android Emulator
Clone the TensorFlow examples GitHub repository to your computer to get the demo application.
git clone https://github.com/tumuyan/ESRGAN-Android-TFLite-Demo
Open the TensorFlow source code in Android Studio. To do this, open Android
Open your terminal and go to the sample folder. Type './gradlew fetchTFLiteLibs' to run the download tasks. Use 'gradlew.bat' on Windows.
Connect the Android device to the computer and be sure to approve any ADB
permission prompts that appear on your phone. Select Run -> Run app.
Select
the deployment target in the connected devices to the device on which the app
will be installed. This will install the app on the device.
To test the app, open the app called TFL Super Resolution
on your device.
Re-installing the app may require you to uninstall the previous installations.
