论文摘要
交互式对象切割工具是图像编辑工作流程的基石。最近的基于深度学习的交互式分割算法在处理复杂图像方面取得了重大进展,通常只需单击几下即可获得粗糙的二进制选择。然而,一旦达到了这种粗暴的选择,深度学习技术就会趋于平稳。在这项工作中,我们将该平台解释为当前算法无法充分利用每个用户互动以及当前培训/测试数据集的局限性。 我们提出了一种新颖的互动架构和一种新颖的培训计划,既量身定制,又是为了更好地利用用户工作流程。我们还表明,通过引入专门为复杂物体边界设计的合成训练数据集,可以进一步获得重大改进。全面的实验支持我们的方法,我们的网络实现了最新的性能。
Interactive object cutout tools are the cornerstone of the image editing workflow. Recent deep-learning based interactive segmentation algorithms have made significant progress in handling complex images and rough binary selections can typically be obtained with just a few clicks. Yet, deep learning techniques tend to plateau once this rough selection has been reached. In this work, we interpret this plateau as the inability of current algorithms to sufficiently leverage each user interaction and also as the limitations of current training/testing datasets. We propose a novel interactive architecture and a novel training scheme that are both tailored to better exploit the user workflow. We also show that significant improvements can be further gained by introducing a synthetic training dataset that is specifically designed for complex object boundaries. Comprehensive experiments support our approach, and our network achieves state of the art performance.
