Complementary Bi-directional Feature Compression for Indoor 360{\deg} Semantic Segmentation with Self-distillation. (arXiv:2207.02437v1 [cs.CV])
cs.CV updates on arXiv.org arxiv.org
Recently, horizontal representation-based panoramic semantic segmentation
approaches outperform projection-based solutions, because the distortions can
be effectively removed by compressing the spherical data in the vertical
direction. However, these methods ignore the distortion distribution prior and
are limited to unbalanced receptive fields, e.g., the receptive fields are
sufficient in the vertical direction and insufficient in the horizontal
direction. Differently, a vertical representation compressed in another
direction can offer implicit distortion prior and enlarge horizontal receptive
fields. In this paper, we combine …
