论文摘要
最近,图像增强和恢复已成为移动设备(例如超分辨率和图像脱毛)上的重要应用。但是,大多数最先进的网络都具有极高的计算复杂性。这使得它们很难在具有可接受的延迟的移动设备上部署。此外,当部署到不同的移动设备时,由于移动设备上深度学习加速器的差异和限制,因此存在较大的延迟变化。在本文中,我们对便携式网络体系结构进行了搜索,以在移动设备之间进行更好的质量扩展折衷。我们进一步介绍了广泛使用的网络优化用于图像去膨胀任务的有效性。本文提供了全面的实验和比较,以发现延迟和图像质量的深入分析。通过上述所有作品,我们通过深度学习加速器的加速度展示了在移动设备上的图像过度应用程序的成功部署。据我们所知,这是第一篇论文,涉及整个移动设备中图像脱毛任务的所有部署问题。本文提供了实用的部署前景,并被冠军赢得的团队在NTIRE 2020年智能手机轨道上的Image Deblurring挑战中采用。
Recently, image enhancement and restoration have become important applications on mobile devices, such as super-resolution and image deblurring. However, most state-of-the-art networks present extremely high computational complexity. This makes them difficult to be deployed on mobile devices with acceptable latency. Moreover, when deploying to different mobile devices, there is a large latency variation due to the difference and limitation of deep learning accelerators on mobile devices. In this paper, we conduct a search of portable network architectures for better quality-latency trade-off across mobile devices. We further present the effectiveness of widely used network optimizations for image deblurring task. This paper provides comprehensive experiments and comparisons to uncover the in-depth analysis for both latency and image quality. Through all the above works, we demonstrate the successful deployment of image deblurring application on mobile devices with the acceleration of deep learning accelerators. To the best of our knowledge, this is the first paper that addresses all the deployment issues of image deblurring task across mobile devices. This paper provides practical deployment-guidelines, and is adopted by the championship-winning team in NTIRE 2020 Image Deblurring Challenge on Smartphone Track.
