Lossless Compression of Point Cloud Sequences Using Sequence Optimized CNN Models
IEEE Access, 2022 In this paper we propose a new paradigm for encoding the geometry of dense point cloud sequences, where a convolutional neural network (CNN), which estimates the encoding distributions, is optimized on several frames of the sequence to be compressed.
