F2 Face Detector Onnx

--- license: unknown library_name: onnxruntime pipeline_tag: object-detection tags: - onnx - face-detection --- # f2 — Face Detector (ONNX) Lightweight face detector (`f2.onnx`) used to localize faces in the PULAO vision pipeline (faces feed the ArcFace embedding model). > ⚠️ **Provenance / license — UNVERIFIED.** The origin of this model is unknown. It is a 2.4 MB detector exported to ONNX from PyTorch; the exact architecture, training data, and license could **not** be determined from the file. This repository is kept **private** until provenance is confirmed. Do not redistribute publicly without first establishing the license. ## Files - `f2.onnx` — 2.4 MB - SHA-256: `15bcd6208f8959b28d07fd8488ec011368d666421eda9674d248f1d48d869ada` ## Inputs / outputs - **Input** `input`: float32 `[1, 3, 320, 320]` (letterboxed square, scaled `1/255`, RGB in this pipeline). - **Output**: face-detection tensor; the pipeline reads `[:, :4]` boxes (xywh) and `[:, 4]` scores, then applies NMS. ## Usage (onnxruntime) ```python import cv2, onnxruntime as ort sess = ort.InferenceSession("f2.onnx", providers=["CPUExecutionProvider"]) blob = cv2.dnn.blobFromImage(img, 1/255, (320, 320), swapRB=True, crop=False) out = sess.run(None, {"input": blob})[0] ``` ## Intended use Face localization feeding ArcFace embedding. Research / prototype only.
