pip install dghs-realutils[gpu]

For more information about installation, you can refer to Installation.

Supported or Developing Features

realutils includes many generic usable features which are available on non-GPU device. For detailed descriptions and examples, please refer to the official documentation. Here, we won't go into each of them individually.

Real Human Photo Tagger

We have tagger for real human photos, like this

We can use get_idolsankaku_tags to tag them

from realutils.tagging import get_idolsankaku_tags

rating, general, character = get_idolsankaku_tags('idolsankaku/1.jpg')
print(rating)

Generic Object Detection

We use official YOLO models the generic purpose of object detections.

We can use detect_by_yolo for generic object detection

from realutils.detect import detect_by_yolo

print(detect_by_yolo('yolo/unsplash_aJafJ0sLo6o.jpg'))
# [((450, 317, 567, 599), 'person', 0.9004617929458618)]
print(detect_by_yolo('yolo/unsplash_n4qQGOBgI7U.jpg'))
# [((73, 101, 365, 409), 'vase', 0.9098997116088867), ((441, 215, 659, 428), 'vase', 0.622944176197052), ((5, 1, 428, 377), 'potted plant', 0.5178268551826477)]
print(detect_by_yolo('yolo/unsplash_vUNQaTtZeOo.jpg'))
# [((381, 103, 676, 448), 'bird', 0.9061452150344849)]
print(detect_by_yolo('yolo/unsplash_YZOqXWF_9pk.jpg'))
# [((315, 100, 690, 532), 'horse', 0.9453459978103638), ((198, 181, 291, 256), 'horse', 0.917123556137085), ((145, 173, 180, 249), 'horse', 0.7972317337989807), ((660, 138, 701, 170), 'horse', 0.4843617379665375)]

More models are hosted on huggingface repository. An online demo are provided as well, you can try it out.

Face Detection

We use YOLO models from deepghs/real_face_detection for face detection.

We can use detect_faces for face detection

from realutils.detect import detect_faces

print(detect_faces('yolo/solo.jpg'))
# [((168, 79, 245, 199), 'face', 0.7996422052383423)]
print(detect_faces('yolo/2girls.jpg'))
# [((721, 152, 1082, 726), 'face', 0.8811314702033997), ((158, 263, 509, 714), 'face', 0.8745490908622742)]
print(detect_faces('yolo/3+cosplay.jpg'))
# [((351, 228, 410, 302), 'face', 0.8392542600631714), ((384, 63, 427, 116), 'face', 0.8173024654388428), ((195, 109, 246, 161), 'face', 0.8126493692398071)]
print(detect_faces('yolo/multiple.jpg'))
# [((1074, 732, 1258, 987), 'face', 0.8792377710342407), ((1378, 536, 1541, 716), 'face', 0.8607611656188965), ((554, 295, 759, 557), 'face', 0.8541485071182251), ((897, 315, 1068, 520), 'face', 0.8539882898330688), ((1194, 230, 1329, 403), 'face', 0.8324605226516724)]

More models are hosted on huggingface repository. An online demo are provided as well, you can try it out.

Feature Extractor

We support DINOv2-based image feature extractor, like this

from realutils.metrics import get_dinov2_embedding

embedding = get_dinov2_embedding('unsplash_0aLd44ICcpg.jpg')
print(embedding.shape)
# (768,)

You can use this embedding, calculating their cosine similarities to measure their visual similarities.

Image-Text Models

We support both CLIP and SigLIP for multimodal alignment operations, like this

• CLIP

from realutils.metrics.clip import classify_with_clip

print(classify_with_clip(
    images=[
        'xlip/1.jpg',
        'xlip/2.jpg'
    ],
    texts=[
        'a photo of a cat',
        'a photo of a dog',
        'a photo of a human',
    ],
))
# array([[0.98039913, 0.00506729, 0.01453355],
#       [0.05586662, 0.02006196, 0.92407143]], dtype=float32)

• SigLIP

from realutils.metrics.siglip import classify_with_siglip

print(classify_with_siglip(
    images=[
        'xlip/1.jpg',
        'xlip/2.jpg',
    ],
    texts=[
        'a photo of a cat',
        'a photo of 2 cats',
        'a photo of 2 dogs',
        'a photo of a woman',
    ],
))
# array([[1.3782851e-03, 2.7010253e-01, 9.7517688e-05, 3.6702781e-09],
#        [3.3248414e-06, 2.2294161e-07, 1.9753381e-09, 2.2561464e-06]],
#       dtype=float32)
