Meta data extraction scripts for images generated with NovelAI's image generation functionality.
nai_meta.py
extracts prompt information and other settings from the alpha channel of NAI generated images. The information is stored in the stealth pnginfo format.
nai_sig.py
will verify the signature in the signed_hash
field, which allows us to verify whether an image was generated by our models. No user specific data is included in this field.
