Hi members, I have created a directory structure as following :

tanks /images

Using following command line tool : Apples-MacBook:Documents rushi$ opencv_annotation -images /tanks/images -annotations /tanks/annotations.txt * mark rectangles with the left mouse button, * press 'c' to accept a selection, * press 'd' to delete the latest selection, * press 'n' to proceed with next image, * press 'esc' to stop. Apples-MacBook:Documents rushi$

But it is not starting any utility so that i can select rectangles of objects. neither it is showing any error too.
