Model card
From the Hugging Face model README
ONNX models from insightface project.
How To Use
pip install dghs-realutils>=0.1.0
from realutils.face.insightface import isf_face_batch_similarity, isf_analysis_faces, isf_faces_visualize
image_path = "/your/image/file"
# get the analysis all the faces
faces = isf_analysis_faces(image_path)
print(faces)
# compare them
print(isf_face_batch_similarity([face.embedding for face in faces]))
# visualize it
isf_faces_visualize(image_path, faces).show()
Available Models
We evaluated all these models with some evaluation datasets on face recognition.
- CFPW (500 ids/7K images/7K pairs)[1]
- LFW (5749 ids/13233 images/6K pairs)[2]
- CALFW (5749 ids/13233 images/6K pairs)[3]
- CPLFW (5749 ids/13233 images/6K pairs)[4]
Below are the complete results and recommended thresholds.
- Det: Success rate of face detection and landmark localization.
- Rec-F1: Maximum F1 score achieved in face recognition.
- Rec-Thresh: Optimal threshold determined by the maximum F1 score.
| Model | Eval ALL (Det/Rec-F1/Rec-Thresh) | Eval CALFW (Det/Rec-F1/Rec-Thresh) | Eval CFPW (Det/Rec-F1/Rec-Thresh) | Eval CPLFW (Det/Rec-F1/Rec-Thresh) | Eval LFW (Det/Rec-F1/Rec-Thresh) |
