Joey's ESRGAN Tutorial

How to use it

1. Put the pictures or textures you want to upscale into the input (found inside the esrgan folder)
2. Open a terminal window and navigate to the esrgan folder (the folder you cloned the fork into in the install guide)
   • For Windows Shift right click in your esrgan folder and select Git Bash Here.
   • For Linux / MacOS users use either the equivalent feature in your file manager or the cd command.
3. Enter:
   1. For Nvidia GPUs

      python upscale.py models/${theModelYouWantToUse}

   2. For other GPUs / integrated Graphic

      python upscale.py --cpu models/${theModelYouWantToUse}

4. Replace ${theModelYouWantToUse} with the name of a model in the models folder.
5. That was it, the results will be in the results folder

Other useful Command line switches are:

• --input ./input - Your Input folder
• --seamless - For seamless textures (Textures that repeat without seams)
• --output ./output - Your Output folder
• --skip_existing - Skipps already upscaled images that are in your output and input folder
• --tile_size 512 - The tile size, if you run out of VRAM, decrease that value
• --binary_alpha - If the alpha / transparency channel should be only black or white
• --alpha_threshold 0.5 Sets tha point at which alpha will be white instead of black if using binary alpha
• --alpha_mode 1 Different implementation for how Alpha works, if you use binary alpha, it must be 1 otherwise you can try 2.
