Efficiently Collecting Training Dataset for 2D Object Detection by Online Visual Feedback

Abstract

Training deep-learning-based vision systems requires the manual annotation of a significant number of images. Such manual annotation is highly time-consuming and labor-intensive. Although previous studies attempted to eliminate the effort required for annotation, the effort required for image collection was retained. To address this issue, we propose a human-in-the-loop dataset-collection method using a web application. To counterbalance workload and performance by encouraging the collection of multi-view object image datasets enjoyably, thereby amplifying motivation, we propose three types of online visual feedback features to track the progress of the collection status. Our experiments thoroughly investigated the influence of each feature on the collection performance and quality of operation. These results indicate the feasibility of annotation and object detection.
