BlazeFace short-range face detector (ONNX)
Google MediaPipe's BlazeFace short-range detector, from the Face Landmarker
.task bundle, converted to ONNX.
- Input
input[1,128,128,3]RGB, normalized to[-1,1], keep-aspect letterboxed (zero border). - Outputs
regressors[1,896,16](box + 6 keypoints per anchor),classificators[1,896,1](score logits). SSD anchors: strides[8,16,16,16], min/max scale 0.1484375/0.75 → 896 anchors; decode + weighted NMS at IoU 0.3. - Feeds the face ROI (rotation from the eye keypoints, 1.5× square-long) to the Face Mesh landmark model.

How it is used
Mirror of one graph from fernandotonon/QtMeshEditor-models
(mocap/…), which QtMeshEditor
downloads on first use for its Performance Capture feature (video/webcam →
facial morph + head + full-body skeletal animation, epic #869). This standalone
repo is for discoverability; the app fetches from the aggregate repo.
