Bounding boxes of text lines are not included in the .json file.
You may compute the convex hull of all character instances in a line as the bounding box of the line.

但是如果有几个文字区域的话(比如三个面馆的横幅) 这种方法好像没办法提取. json里面没有对不同的区域做个划分. 只是给出了每个字的label . 我现在用yolov3训练的模型只能检测出来单个字. 我需要这个区域的目的就是先检测区域 .再扣字做识别. 另外请问一下论文里面说的这个文字区域标记的json有没有下载链接呀 谢谢.

You may compute the convex hull (or minimum area rectangle) of character instances in a line as the region of the line.
