GwenRB/cosplay-characters

Cosplay character classifier

Tells which character a cosplayer is dressed as, from a photo: 396 characters from anime, games, comics and films, some with their costume variants (2B (Christmas), Marin Kitagawa (Rizu Kyun)).

It recognises the costume, not the person: every class is a character, never a cosplayer.

Use it

import timm, torch
from PIL import Image, ImageOps

model = timm.create_model("hf-hub:GwenRB/cosplay-characters", pretrained=True).eval()
transform = timm.data.create_transform(**timm.data.resolve_data_config(model=model))
names = model.pretrained_cfg["label_names"]

with Image.open("photo.jpg") as im:
    x = transform(ImageOps.exif_transpose(im).convert("RGB"))[None]
with torch.no_grad():
    probs = model(x).softmax(1)[0]
for p, i in zip(*probs.topk(3)):
    print(f"{names[i]:<30} {p:.1%}")

The transform squashes the whole photo into 224×224 instead of cropping its centre, as in training. A centre crop also runs, but is less accurate.

It always answers with one of its 396 characters, even for a photo of someone out of costume or dressed as a character it doesn't know. Treat answers under about 50% as "not sure".

Training

• Base: vit_base_patch16_siglip_224.v2_webli (SigLIP 2 ViT-B/16), fully fine-tuned.
• Data: photos of cosplayers in costume, from their public posts, sorted by character by hand and with the help of earlier versions of this model. A character needs a few photos on each side of the split to be included.
• Validation: top-1 98.1%, macro-F1 97.0%.

The validation photos are split from the same collection by file, so the same cosplayers, and often the same photo shoots, are on both sides. Expect lower accuracy on cosplayers the model has never seen.
