Doc-UFCN - NorHand v1 - Line detection

The NorHand v1 line detection model predicts text lines from NorHand document images. This model was developed during the HUGIN-MUNIN project.

Model description

The model has been trained using the Doc-UFCN library on NorHand document images. It has been trained on images with their largest dimension equal to 768 pixels, keeping the original aspect ratio. The model predicts two classes: vertical and horizontal text lines.

Evaluation results

The model achieves the following results:

set	class	IoU	F1	AP@[.5]	AP@[.75]	AP@[.5,.95]
train	vertical	88.29	89.67	71.37	33.26	36.32
	horizontal	69.81	81.35	91.73	36.62	45.67
val	vertical	73.01	75.13	46.02	4.99	15.58
	horizontal	61.65	75.69	87.98	11.18	31.55
test	vertical	78.62	80.03	59.93	15.90	24.11
	horizontal	63.59	76.49	95.93	24.18	41.45
