XLSR-Quantized: Upscale images in real time

XLSR is designed for lightweight real-time upscaling of images.

This is based on the implementation of XLSR-Quantized found here. This repository contains scripts for optimized on-device export suitable to run on Qualcomm® devices. More details on model performance accross various devices, can be found here.

Sign up for early access to run these models on a hosted Qualcomm® device.

Example & Usage

Once installed, run the following simple CLI demo:

python -m qai_hub_models.models.xlsr_quantized.demo

More details on the CLI tool can be found with the --help option. See demo.py for sample usage of the model including pre/post processing scripts. Please refer to our general instructions on using models for more usage instructions.

Export for on-device deployment

This repository contains export scripts that produce a model optimized for on-device deployment. This can be run as follows:

python -m qai_hub_models.models.xlsr_quantized.export

Additional options are documented with the --help option. Note that the above script requires access to Deployment instructions for Qualcomm® AI Hub.
