Outline of Final Research Achievements

As an examples of task-driven image processing, we put our focus on tiny object detection and image super-resolution as a task and an image processing algorithm, respectively. Different from previous approaches in which these image processing and task are achieved independently, our proposed framework (i) integrates these two sub-problems in a single neural network and (ii) trains this network so that the reconstructed super-resolution image is optimized for improving the tiny object detection task. With this framework, we realize image super-resolution for generating images that are understandable by artificial intelligence instead of image super-resolution for images that are observed by human.
