Title:
3D DATA ENCODING DEVICE AND 3D DATA DECODING DEVICE
Document Type and Number:
Japanese Patent JP2023142460
Kind Code:
A
Abstract:
To reduce distortion caused by encoding and encode/decode 3D data with high quality using existing video encoding methods.SOLUTION: A 3D data decoding device that decodes 3D encoded data includes a geometry image decoding unit that decodes a geometry image from the 3D encoded data, an attribute image decoding unit that decodes an attribute image from the 3D encoded data, a geometry image filter unit that performs filter processing on the geometry image, and an attribute image filter unit that performs filter processing on the attribute image, and the geometry image filter unit and/or the attribute image filter unit decodes a filter parameter including information indicating that a filter target is a 3D data (V3C) component, and on the basis of the filter parameter, the filter processing of the geometry image filter unit and/or the attribute image filter unit is executed.SELECTED DRAWING: Figure 6
