We present a novel approach to unsupervised learning for video object segmentation (VOS). In contrast to previous methods, our approach learns dense feature representations directly in a fully-convolutional regime. We rely on uniform grid sampling to extract a set of anchors and train our model to disambiguate between them on the inter- and intra-video levels. A naive scheme to train such a model results in a degenerate solution. However, we prevent it with simple regularisation accommodating equivariance property of the segmentation task to similarity transformations. Notably, our training objective with the regularisation can be jointly expressed by a single loss term. On established VOS benchmarks, our approach reaches segmentation accuracy on par or even higher than previous works despite using significantly less training data and compute power.We present a novel approach to unsupervised learning for video object segmentation (VOS).

Neural Information Processing Systems (NeurIPS) is a multi-track machine learning and computational neuroscience conference that includes invited talks, demonstrations, symposia and oral and poster presentations of refereed papers. Following the conference, there are workshops which provide a less formal setting.
