Abstract

An apparatus to facilitate processing video bit stream data is disclosed. The apparatus includes one or more processors to encode surface normals data with point cloud geometry data included in the video bit stream data for reconstruction of objects within the video bit stream data based on the surface normals data and a memory communicatively coupled to the one or more processors.

First claim

What is claimed is:

1. A method to facilitate processing video bit stream data, comprising estimating relative location and intensity of light sources in a 360° six degrees of freedom (6 DoF) scene, including:
generating point clouds from the 6 DoF scene;
computing surface normals, determining whether light intensity peaks for objects in the 6 DoF scene are higher than a predetermined threshold difference; and
performing light estimations for each object upon a determination that the light intensity peaks are higher than a predetermined threshold difference.

2. The method of claim 1 , further comprising mapping light estimations to the 6 DoF scene.

3. At least one non-transitory computer readable medium having instructions stored thereon, which when executed by one or more processors, cause the processors to:
estimate relative location and intensity of light sources in a 360° six degrees of freedom (6 DoF) scene, including:
generating point clouds from the 6 DoF scene;
computing surface normals, determining whether light intensity peaks for objects in the 6 DoF scene are higher than a predetermined threshold difference; and
performing light estimations for each object upon a determination that the light intensity peaks are higher than a predetermined threshold difference.

4. The computer readable medium of claim 3 , having instructions stored thereon, which when executed by one or more processors, further cause the processors to map light estimations to the 6 DoF scene.

5. An apparatus to facilitate light estimation, comprising:
one or more processors to estimate relative location and intensity of light sources in a 360° six degrees of freedom (6 DoF) scene, including, generating point clouds from the 6 DoF scene, computing surface normals, determining whether light intensity peaks for objects in the 6 DoF scene are higher than a predetermined threshold difference and performing light estimations for each object upon a determination that the light intensity peaks are higher than a predetermined threshold difference; and
a memory communicatively coupled to the one or more processors.

6. The apparatus of claim 5 , wherein the one or more processors further to map light estimations to the 6 DoF scene.
