Title:
DECODING METHOD, ENCODING METHOD, AND DECODING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/199675
Kind Code:
A1
Abstract:
This decoding method is for decoding a plurality of encoded three-dimensional points each having position information including a distance component, a first direction component, and a second direction component. The decoding method comprises: determining (S211) a method of entropy decoding and/or a method of multivalue conversion of information about a first encoded three-dimensional point included in the plurality of encoded three-dimensional points according to, among a plurality of decoded three-dimensional points, the number of second three-dimensional points having a first direction component and a second direction component substantially equal to the first direction component and the second direction component, respectively, of the first encoded three-dimensional point; and performing (S212) a process using the determined method(s).
