The Private Object Vanished Before the Room Became 3D
InViStream masks both color and depth at the camera side so hidden objects cannot reappear when multiple views fuse in the cloud.
Summary
InViStream masks both color and depth at the camera side so hidden objects cannot reappear when multiple views fuse in the cloud.
Ordinary frame redaction can fail in volumetric video because another camera or the depth map may restore a private object. InViStream propagates public/private decisions across calibrated RGB-D views and sends only sanitized point clouds to fusion. On synthetic and real office-like scenes, the authors report recall near 0.89 and 0.91, structural similarity above 0.98 in synthetic tests and throughput above 30 frames per second. The evaluation covers the reported datasets and object policy, not every capture environment or privacy threat.
Why it matters
