| # LibreDDColort-restore |
|
|
| DDColor automatic image colorization with the ConvNeXt-T encoder, converted |
| for LibreYOLO's existing `restore` task. The network predicts Lab chroma at |
| 512 square and reconstructs RGB on the source canvas using the original |
| luminance plane. |

|
|
| Learned tensors are unchanged. Conversion adds LibreYOLO v1 checkpoint |
| metadata. Network parity is exact (`max_abs_diff=0`), and the complete |
| OpenCV Lab pipeline is pixel-identical to the pinned reference. |
