Rethinking Space Time Networks With Improved Memory Coverage For This paper presents a simple yet effective approach to modeling space time correspondences in the context of video object segmentation. unlike most existing approaches, we establish correspondences directly between frames without re encoding the mask features for every object, leading to a highly efficient and robust framework. Abstract fective approach to modeling space time cor respondences in the context of video object segmentation. unlike most existing approaches, we establish correspondences directly between frames witho t re encoding the mask features for every object, leading to a highly efficient and robust framework. with the correspondences, every node i.

Robust And Efficient Memory Network For Video Object Segmentation Deepai 针对视频实例分割问题，本文提出了一种简单而高效的方法对时空对应性 (space time correspondence) 进行建模，能够直接得到帧间对应关系而不用对每个目标物体都进行mask features的re encoding。 本文方法是对stm (space time memory networks) 的简化，想要得到matching networks的极简形式，提升性能、减少memory usage，更有效的利用memory种的信息。 具体来说： 本文用negative squared euclidean distance来代替dot product作为相似度衡量的依据，也将二者进行有效的协同，让性能提升更多。.

We propose stcn with direct image to image correspondence that is simpler, more efficient, and more effective than stm. we examine the affinity in detail, and propose using l2 similarity in place of dot product for a better memory coverage, where every memory node contributes instead of just a few. Space time memory (stm) network methods have been dominant in semi supervised video object segmentation (svos) due to their remarkable performance. in this work, we identify three key aspects where we can improve such methods; i) supervisory signal, ii) pretraining and iii) spatial awareness. The synergy of correspondence networks and diversified voting works exceedingly well, achieves new state of the art results on both davis and vos datasets while running significantly faster at 20 fps for multiple objects without bells and whistles. Enomenon, we propose using the negative squared euclidean distance instead to compute the affinities. we validate that every memory node now has a chance to contribute, and experiment.
