Latest Patents

Mulard is credited with 1 patent, titled “Dynamic Block Decimation in V-PCC Decoder.” The invention proposes decoding blocks within Video-based Point Cloud Compression (V-PCC) patches at reduced resolutions to make point-cloud rendering less computationally intensive.

The method uses rendering information to assess whether reconstructed points are likely to be visible to a user. It can evaluate patches, block components, or individual pixels, then determine whether an area should be rendered and at what resolution while seeking to preserve visual quality. The described approaches include comparing distance to the screen against distance thresholds and comparing screen-coordinate distances between adjacent projected points.
