Title: Transferable Recognition-Aware Image Processing. Abstract: Recent progress in image recognition has stimulated the deployment of vision systems at an unprecedented scale. As a result, visual data are now often consumed not only by humans but also by machines. Existing image processing methods only optimize for better human perception, yet the resulting images may not be accurately recognized by machines. This can be undesirable, e.g., the images can be improperly handled by search engines or recommendation systems. In this work, we propose simple approaches to improve machine interpretability of processed images: optimizing the recognition loss directly on the image processing network or through an intermediate transforming model. Interestingly, the processing model's ability to enhance recognition quality can transfer when evaluated on models of different architectures, recognized categories, tasks and training datasets. This makes the solutions applicable even when we do not have the knowledge of future recognition models, e.g., if we upload processed images to the Internet. We conduct experiments on multiple image processing tasks, with ImageNet classification and PASCAL VOC detection as recognition tasks. With our simple methods, substantial accuracy gain can be achieved with strong transferability and minimal image quality loss. Through a user study we further show that the accuracy gain can transfer to a black-box, third-party cloud model. Finally, we try to explain this transferability phenomenon by demonstrating the similarities of different models' decision boundaries.
