Abstract
A method and a device for generating a data stream representative of a volumetric video generated from a sequence of multi-plane images are disclosed. A quantization law depending on an angular resolution used to generate patches from the multi-plane images is set up. For each intra-periods of the frame sequence, patches are generated for a given angular resolution. If generated patches do not fit in atlas images of a target size, the angular resolution is decreased and patches are generated again according to this new angular resolution.
Claims12
A method comprising:
- generating patches by aggregating not totally transparent parts of a multi-plane image and by using a quantization law depending on an angular resolution, wherein the multi-plane image comprises a number of layers and is representative of a three-dimensional scene;
- determining that the generated patches cannot be packed in an atlas image of a given size;
- and
- responsive to the determining, decreasing the angular resolution and repeating generating patches.
A device comprising a processor configured to perform:
- generating patches by aggregating non totally transparent parts of a multi-plane image and by using a quantization law depending on an angular resolution, wherein the multi-plane image comprises a number of layers and is representative of a three-dimensional scene;
- determining that the generated patches cannot be packed in an atlas image of a given size;
- and
- responsive to the determining, decreasing the angular resolution and repeating generating patches.
