+ # Generic historical line detection
18
+
19
+ The generic historical line detection model predicts text lines from document images.
20
+
21
+ ## Model description
22
+
23
+ The model has been trained using the Doc-UFCN library on 10 historical document datasets including these public datasets:
24
+ * [Bozen](https://zenodo.org/record/218236)
25
+ * [cBAD2017 (READ)](https://zenodo.org/record/1491441)
26
+ * [cBAD2019](https://zenodo.org/record/2567398)
27
+ * [DIVA-HisDB](https://diuf.unifr.ch/main/hisdoc/diva-hisdb.html)
28
+ * [Horae](https://github.com/oriflamms/HORAE/)
29
+ * [ScribbleLens](https://www.openslr.org/84/)
30
+
31
+ It has been trained on images with their largest dimension equal to 768 pixels, keeping the original aspect ratio.
32
+
33
+ ## Evaluation results
34
+
35
+ The model achieves the following results on the test sets:
36
+
37
+ | | IoU | F1 | AP@[.5] | AP@[.75] | AP@[.5,.95] |
38
+ | ----------------------- | ----- | ----- | ------- | -------- | ----------- |

42

43
+ | DIVA-HisDB | 41.54 | 57.88 | 63.15 | 0.00 | 11.69 |
44
+ | Horae | 48.93 | 63.95 | 57.45 | 5.20 | 15.55 |
45
+ | ScribbleLens | 76.61 | 86.72 | 98.02 | 71.87 | 58.32 |
46
+
47
+ The model has been trained to reduce mergers in predictions (see the [paper](https://link.springer.com/article/10.1007/s10032-022-00395-7) for more details on training). Therefore, despite slightly low evaluation values, the model correctly detects lines on a wide variety of historical and modern manuscript documents.
