I'm preparing a object detection data set with 15,000 images. And our university is planning to open source the data set. I'm confused which format should I use to annotate labels( Kitti or PASCAL VOC) since DIGITS uses kitti format. I have seen that most of the standard data-set's like Imagenet, MS COCO use PASCAL VOC format(XML file). But Kitti uses different format. There are many pretty good GUI tools for annotating images in PASCAL VOC format, are there any GUI tools to annotate images in Kitti format. If so, please tell me. And can we convert one format into other.
