Texts as Lines: Text Detection with Weak Supervision

Table 3

Effectiveness of label enhancement and the pretrained model on Total-Text.

Method	Pretrain-enhancement	Label	F-measure
Baseline + TL	No	TL	65.0
Baseline + FL	No	Full	81.1
Baseline + TL + PT	SynthText	TL	77.6
Baseline + TL + PT	CTW1500	TL	79.1
Baseline + TL + PT	SynthText	TL	77.2

FL and TL refer to using full mask and text line label, respectively. TL is the synthetic text line label. PT and PT are the different models pretrained on SynthText and CTW1500, respectively.
