Title:
POINT CLOUD COMPRESSION METHOD, ENCODER, DECODER, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/244363
Kind Code:
A1
Abstract:
Disclosed are a point cloud compression method, an encoder, a decoder, and a storage medium. The method comprises: obtaining the current block of a video to be encoded; determining geometric information of point cloud data of the current block and corresponding attribute information; performing down-sampling on the geometric information and the corresponding attribute information by using a sparse convolutional network so as to obtain hidden layer features; and compressing the hidden layer features to obtain a compressed code stream.
