"Each image will have one or more polygons to identify the object in the image.
The objective is to check each image to make sure that the figure on the image are correctly segmented by a polygon (excluding any background). If it's not, then add a polygon (means closed figure or draw outline around object) to do so.

Use the "Start bounding box" tool to ouline a box object .

If there is any circle object draw outline in the outter circle only .
