Abstract: A three-dimensional data encoding method that is for encoding a three-dimensional point that has attribute information. The three-dimensional data encoding method involves calculating a prediction value for the attribute information of the three-dimensional point (S3061), calculating a prediction residual that is the differences between the prediction value and the attribute information of the three-dimensional point (S3062), generating binary data by binarizing the prediction residual (S3063), and arithmetically encoding the binary data (S3064). The arithmetic encoding may, for example, use a different encoding table for each bit of the binary data.

Abstract: This three-dimensional data encoding method includes: adding, to a bitstream, first information indicating whether a leaf included in an N-branched tree structure (N is an integer of 2 or greater) having multiple three-dimensional points included in three-dimensional data, includes one three-dimensional point or includes two or more three-dimensional points (S2221); and when the first information indicates that the leaf includes one three-dimensional point (Yes in S2222), generating an N-branched tree structure such that the leaf includes one three-dimensional point (S2223) and encoding the N-branched tree structure (S2224), whereas when the first information indicates that the leaf includes two or more three-dimensional points (No in S2222), generating an N-branched tree structure such that the leaf includes two or more three-dimensional points (S2225) and encoding the N-branched tree structure (S2226).

Abstract: An image decoding method of decoding, on a per-block basis, a coded image included in a bitstream, includes: performing arithmetic decoding on a current block to be decoded (S101); determining whether or not the current block is at the end of a slice(S103); determining, when it is determined that the current block is not at the end of the slice, whether or not the current block is at the end of a sub-stream which is a structural unit of the image that is different from the slice (S105); and performing arithmetic decoding on a sub-last bit and performing arithmetic decoding termination, when it is determined that the current block is at the end of the sub-stream (S106).
