Task1-- Detection with oriented bounding boxes

 The aim of this task is to locate the ground object instances with an OBB.

 
 

Task2-- Detection with horizontal bounding boxes

The aim of this task is to accurately localize the instance in terms of horizontal bounding box with (xmin, ymin, xmax, ymax) format.
