hi, thanks for your wonderful work. i want to ask a question about the annotations you have provided. I found that there is a deviation between the annotations you provided and the original annotation. most annotation["polys"] is beyond the annotation["bbox"].
for example, in the ctw1500_test_1001.jpg,
annotation["id"] = 1, annotation["img_ids"] = 1001, annotation["bbox"] = [45, 56.6, 90, 27.4]
annotation["polys"] = [45, 73, 64.01, 64.83, 76.64, 59.36, 85.5, 56.61, 93.17, 56.59, 102.24, 59.3, 115.32, 64.77, 135, 73, 130, 84, 111.29, 77.2, 100.05, 72.21, 93.21, 69.31, 87.68, 68.77, 80.36, 70.85, 68.16, 75.84, 48, 84] , 56.59 is less than 56.6.
annotation["area"] = 1092, not equal with 90x27.4=2466.
and the original annotation["polys"] = [48. 84, 61, 79, 75, 73, 88, 68, 102, 74, 116, 79, 130, 84, 135, 73, 119, 67, 104, 60, 89, 56, 74, 61, 59, 67, 45, 73]
can u explain about that? and if have any script for convert the original annotation to coco format? if you do, can you share it?

For the Bezier annotation, the bounding polygon of the Bezier curve may well exceed the bounding box.

The script will be posted in #3 once ready.
