How to Use

Simply connect an image to the Global Restoration node to process; if the image contains scratch artifacts, use the Global Restoration with Scratch Processing node instead.

To improve the faces, connect the image to the Face Detection node then the Face Enhancement node, then connect the enhanced output and the image both to the Face Align node in the end to merge the results.

Settings

• HR: Use some higher parameters during the processings
• GPU_ID: Specify the GPU to use
  • Set it to -1 to use CPU if you do not have a Nvidia GPU or are getting Out of Memory Error
