Query: Trimap-guided Feature Mining and Fusion Network for Natural Image
  Matting   Utilizing trimap guidance and fusing multi-level features are two important
issues for trimap-based matting with pixel-level prediction. To utilize trimap
guidance, most existing approaches simply concatenate trimaps and images
together to feed a deep network or apply an extra network to extract more
trimap guidance, which meets the conflict between efficiency and effectiveness.
For emerging content-based feature fusion, most existing matting methods only
focus on local features which lack the guidance of a global feature with strong
semantic information related to the interesting object. In this paper, we
propose a trimap-guided feature mining and fusion network consisting of our
trimap-guided non-background multi-scale pooling (TMP) module and global-local
context-aware fusion (GLF) modules. Considering that trimap provides strong
semantic guidance, our TMP module focuses effective feature mining on
interesting objects under the guidance of trimap without extra parameters.
Furthermore, our GLF modules use global semantic information of interesting
objects mined by our TMP module to guide an effective global-local
context-aware multi-level feature fusion. In addition, we build a common
interesting object matting (CIOM) dataset to advance high-quality image
matting. Experimental results on the Composition-1k test set, Alphamatting
benchmark, and our CIOM test set demonstrate that our method outperforms
state-of-the-art approaches. Code and models will be publicly available soon.
