## Dataset Creation

### Curation Rationale

At present, text orientation is not diverse enough in the existing scene text datasets. Specifically, curve-orientated text is
largely out-numbered by horizontal and multi-oriented text, hence, it has received minimal attention from the community so
far. Motivated by this phenomenon, the authors collected a new scene text dataset, Total-Text, which emphasized on text orientations
diversity. It is the first relatively large scale scene text dataset that features three different text orientations: horizontal, multioriented,
and curve-oriented.

#### Annotation process

<!-- This section describes the annotation process such as annotation tools used in the process, the amount of data annotated, annotation guidelines provided to the annotators, interannotator statistics, annotation validation, etc. -->
Initial version of Total-Text’s polygon annotation was carried out with the mindset of covering text instances tightly with
the least amount of vertices. As a result, the uncontrolled length of polygon vertices is not practical to train a regression
network. The authors refined the Total-Text annotation using the following scheme. Apart from setting the number 
of polygon vertices to 10 (empirically, 10 vertices are found to be sufficient in covering all the word-level text instances
tightly in our dataset), they used a guidance concept inspired by Curved scene text detection via transverse and longitudinal 
sequence connection paper by Liu, et al. which was introduced to remove human annotators’ bias and in turn producing a more consistent ground truth.
The process for other annotations can be referred from paper. 

The authors have mentioned in the paper that the human annotator was given the freedom to take a break whenever he feels like to, 
ensuring that he will not suffer from fatigue which in turn introduces bias to the experiment. Both time and annotation quality 
were measured internally (within the script) and individually to each image.

The authors have also proposed aided scene text detection annotation tool, T3, could help in providing a better scene text dataset in terms of quality and scale. 

#### Who are the annotators?
