We introduce ReConvNet, a recurrent convolutional architecture for
semi-supervised video object segmentation that is able to fast adapt its
features to focus on any specific object of interest at inference time.
Generalization to new objects never observed during training is known to be a
hard task for supervised approaches that would need to be retrained. To tackle
this problem, we propose a more efficient solution that learns spatio-temporal
features self-adapting to the object of interest via conditional affine
transformations. This approach is simple, can be trained end-to-end and does
not necessarily require extra training steps at inference time. Our method
shows competitive results on DAVIS2016 with respect to state-of-the art
approaches that use online fine-tuning, and outperforms them on DAVIS2017.
ReConvNet shows also promising results on the DAVIS-Challenge 2018 winning the
$10$-th position.

ReConvNet 是一种循环卷积架构，用于半监督视频对象分割，能够快速适应其特征以聚焦于感兴趣的任何特定对象。通过条件仿射变换学习自适应于感兴趣的对象的时空特征的方法，不需要额外的推断时间内的训练步骤，且在 DAVIS2016 上表现出有竞争力的结果。
