LibreViTMattes-matte

Pretrained checkpoint restriction

NON-COMMERCIAL. This checkpoint was trained on Adobe Composition-1k. Adobe's Deep Image Matting Dataset License Agreement says models may only be used and distributed for non-commercial purposes and may not be sold. Permitted distribution must retain the required Deep Image Matting CVPR 2017 attribution. Read LICENSE before use or redistribution.

The restriction applies to this pretrained checkpoint, not to LibreYOLO's MIT code or to independently trained ViTMatte weights with suitable provenance.

Use

LibreViTMatte provides trimap-guided alpha matting under LibreYOLO's existing matte task. The trimap must use exactly 0/128/255 (or normalized 0/0.5/1) for known background, unknown, and known foreground.

python

from libreyolo import LibreYOLO

model = LibreYOLO("LibreViTMattes-matte.pt")
result = model("portrait.jpg", trimap="trimap.png")
alpha = result.matte.array

The result is a soft float32 alpha matte on the source canvas. Known background and foreground pixels are forced to exactly zero and one.

Learned tensors are unchanged. Conversion adds LibreYOLO v1 checkpoint metadata. Preprocessing, raw alpha, and constrained-alpha parity with the pinned Transformers reference are bit-exact.
