METHOD & APPARATUS FOR POINT CLOUD COLOR PROCESSING

摘要: A method for reducing color leaking artefacts in an image formed by projection processing from a 3D point cloud comprises: receiving input comprising the cloud; classifying into plurality of surface patches; projecting patches onto plane to form first 2D image; image, coding, transmitting and decoding, final providing as output. Processing comprises at least one of: coding independent patch reduce inter-patch leakage; background filling pixels between applying chroma down-sampling scheme, based on depth value, that reduces intra-patch decoding post-filtering detect potential leakage, followed adaptive up-sampling scheme leakage.
