Preprocessing helpers for recognition ONNX inputs.

Functions

Name	Description
normalize_aligned_keypoints	Normalize aligned 5-point keypoints to the [0, 1] ONNX input frame.
to_ada_input	Convert aligned BGR face crop(s) to AdaFace-style NCHW input.

    *,
    model_name,
    image_size=(112, 112),
)

Normalize aligned 5-point keypoints to the [0, 1] ONNX input frame.

to_ada_input

preprocessing.to_ada_input(aligned_bgr_img, *, image_size=(112, 112))
