Predictive bounding boxes: A machine learning powered image annotation tool for creating high quality training data for object detection


The state of the art deep learning models for object detection require large volume of high quality training data to perform well. While the advances of data collection technology have enabled the acquisition of a massive volume of data, labeling the data remains an expensive and time-consuming task In this study, we propose a new interface for bounding box annotation which uses machine learning to accelerate the annotation and increase the quality of training data, lowering cost and time required to complete the task. In particular we study challenging tasks such as drawing bounding boxes for large images that contains many objects at different scales such as drone and satellite imagery. We study and measure the user interactions with the tool and their performance through launching multiple jobs on a crowdsourced based data labeling platform to understand the best design of the machine learning powered interface. Results demonstrate employing machine learning with the proposed design dramatically increases the accuracy of bounding boxes adjusted by humans.
