Query: Semantic Amodal Segmentation   Common visual recognition tasks such as classification, object detection, and
semantic segmentation are rapidly reaching maturity, and given the recent rate
of progress, it is not unreasonable to conjecture that techniques for many of
these problems will approach human levels of performance in the next few years.
In this paper we look to the future: what is the next frontier in visual
recognition?
  We offer one possible answer to this question. We propose a detailed image
annotation that captures information beyond the visible pixels and requires
complex reasoning about full scene structure. Specifically, we create an amodal
segmentation of each image: the full extent of each region is marked, not just
the visible pixels. Annotators outline and name all salient regions in the
image and specify a partial depth order. The result is a rich scene structure,
including visible and occluded portions of each region, figure-ground edge
information, semantic labels, and object overlap.
  We create two datasets for semantic amodal segmentation. First, we label 500
images in the BSDS dataset with multiple annotators per image, allowing us to
study the statistics of human annotations. We show that the proposed full scene
annotation is surprisingly consistent between annotators, including for regions
and edges. Second, we annotate 5000 images from COCO. This larger dataset
allows us to explore a number of algorithmic ideas for amodal segmentation and
depth ordering. We introduce novel metrics for these tasks, and along with our
strong baselines, define concrete new challenges for the community.
