Ground Truth (GT) Format

We create a single JSON file for each video in the dataset to store the ground truth in a structured format, following the naming convention: gt_[frame_id], where frame_id refers to the index of the video frame in the video

In a JSON file, each gt_[frame_id] corresponds to a list, where each line in the list correspond to one word in the image and gives its bounding box coordinates, transcription, text type(caption or scene text) and tracking ID, in the following format:

{

“frame_1”:

[

{

"points": [x1, y1, x2, y2, x3, y3, x4, y4],

“tracking ID”: "1" ,

“transcription”: "###",

“category”: title/caption/scene text,

“language”: Chinese/English,

“ID_transcription“: complete words for the whole trajectory

},

…

{

"points": [x1, y1, x2, y2, x3, y3, x4, y4],

“tracking ID”: "#" ,

“transcription”: "###",

“category”: title/caption/scene text,

“language”: Chinese/English,

“ID_transcription“: complete words for the whole trajectory

}
