Texts as Lines: Text Detection with Weak Supervision

Table 6

Effectiveness of different text line labelling qualities on Total-Text.

Width (pixel)	Method	F-measure	Method	F-measure
1	Baseline + TL	77.2	Baseline + TL	77.6
3	Baseline + TL	77.8	Baseline + TL	77.8
5	Baseline + TL	77.5	Baseline + TL	78.4
7	Baseline + TL	78.1	Baseline + TL	78.3
Method	Width (pixel)	Offset (%)	F-measure	—
Baseline + TL	1	0	77.6	—
Baseline + TL	1	10	77.4	—
Baseline + TL	1	20	77.8	—
Baseline + TL	1	30	76.4	—
Baseline + TL	1	40	75.2	—

TL is the synthetic text line with a full mask. TL refers to the manually marked text line.
