Tagging methodology for Kazusa (blue archive)
Start with WD1.4 Swinv2 at 0.25 confidence.
- Tag unique features
- `halo` / `demon horns` / `low wings`
- Remove when not present or out of view. WD1.4 likes putting `halo` even on images where no halo is visible.
- Kazusa: `halo` / `animal ears`
- Pruned `extra ears` as it seems redundant.
- Tag outfit variants with a single master tag
- Kazusa:
- Uniform: `school uniform` / `black jacket`
- Sometimes the jacket appears without anything else, which was not tagged `school uniform`
- Non-canon costumes
- Add `alternate costume`
- Nudity (WD1.4 usually does this accurately)
- `nude` / `completely nude`
- Prune eye colors
- Keep tags which describe unusual eye features (`multicolored eyes`, `heterochromia`, `slit pupils`) as they can otherwise be too subtle and inconsistently drawn for the AI to learn
- Prune hair colors
- This includes `two-toned hair`, `gradiant hair`, etc. The AI learns all of these very consistently without the tags, likely because artists tend to draw them consistently
- Partially prune hair styles
- Leave key style tags like `twintails`, `ponytail`, `short hair with long locks`.
- Prune exceedingly common tags like `bangs` / `sidelocks` / `eyebrows visible through hair` / `hair between eyes`, etc.
- Prune length, except for images which differ from the character's usual length
- Add `alternate hairstyle` and/or `alternate hair length` for these
- Kazusa: `short hair, colored inner hair` -- while I would usually prune these, they're really her only defining hairstyle traits
- Fixup hair ornaments
- Prune generic `hair ornament` in favor of more specificity
- `hairclip` / `black headband` / `hair flower` / `hair ribbon`, etc.
- Consolidate tags that have color variants (`headband` >> `black headband`)
- Kazusa: `hairclip`
- Consolidate outfits
- Only tag an item when it is actually visible. If it is only barely visible along the edge of an image, keep in mind it may be cropped during bucketing.
- Danbooru's wiki entry for a character often provides a good list of tags commonly used to describe a character's outfits.
- Kazusa outfits:
- School Uniform
- `black choker`
- `hooded jacket`
- `black jacket`
- `green sailor collar`
- `pink neckerchief`
- `miniskirt`
- `pleated skirt`
- `white skirt`
- `black pantyhose`
- `sneakers`
- Fixup sleeves
- ie. `long sleeves` / `puffy long sleeves` / `detached sleeves`
- You only need one, but pick one and be consistent. If sleeves aren't tagged properly the tends to add them inappropriately (such as when prompting for sleeveless outfits or nudity)
- Fixup collars
- ie. `detached collar` / `collared shirt` / `choker` / etc.
- Same deal as sleeves, they tend to appear when unwanted if not consistently tagged according to visibility in the training data.
- Fixup clothing state
- ie. `open jacket` / `open shirt` / `partially undressed` / `off shoulder`
- The tagger is generally pretty good at this.
- Tag expressions
- WD1.4 rarely tags these, but doing them manually can help the AI reproduce a character's iconic expressions well.
- Start by searching for images without one of these, and add them.
- `open mouth`
- `closed mouth`
- `parted lips`
- Add less common expressions
- `smile` / `light smile` / `:d`
- `wavy mouth` / `embarrassed`
- `flustered` / `panicked` / `swirly eyes` / `@_@`
- `surprised` / `o_o` / `wide-eyed`
- `upset` / `annoyed` / `frustrated` / `v-shaped eyebrows`
- `naughty face` / `seductive smile`
- `smug` / `:3`
- `eyes closed` / `one eye closed`
- WD1.4 usually gets these for you.
- Tag camera angles/composition
- `cowboy shot`
- `upper body`
- `full body`
- `portrait`
- `cropped torso` / `cropped legs`
- `feet out of frame`
- `from side` / `from above` / `from below` / `from behind`
- Tag iconic poses/actions
- ie. `v` / `standing on one leg`
- Kazusa
- `mouth hold`
- `eating`
- `macaroon`
- Flip through each image and use Hydrus's "related tags" feature to quickly identify important tags that might be missing.
- This feature looks at other images with similar tags to provide suggestions.
