title: How to prepare training data for image segmentation
body: <p>I am using bounding box marking tools like BBox and YOLO marker for object localisation. I wanted to know is there any equivalent marking tools available for image segmentation tasks. How people in academia and research are preparing data sets for these image segmentation tasks. Recent Kaggle competition <a href="https://www.kaggle.com/c/severstal-steel-defect-detection" rel="nofollow noreferrer">severstal-steel-defect-detection</a> has pixel level segmentation information. Which tool they used to prepare this data?</p>
