Occupancy Planes for Single-view RGB-D Human Reconstruction. (arXiv:2208.02817v1 [cs.CV])

Single-view RGB-D human reconstruction with implicit functions is often
formulated as per-point classification. Specifically, a set of 3D locations
within the view-frustum of the camera are first projected independently onto
the image and a corresponding feature is subsequently extracted for each 3D
location. The feature of each 3D location is then used to classify
independently whether the corresponding 3D point is inside or outside the
observed object. This procedure leads to sub-optimal results because
correlations between predictions for neighboring locations …
