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.
