Abstract: In this three-dimensional data encoding method: a plurality of attribute information pieces of a corresponding plurality of three-dimensional points (S6701) are encoded using a parameter; and a bit stream including the plurality of encoded attribute information pieces, control information, and a plurality of first attribute control information pieces is generated (S6702). The control information corresponds to the plurality of attribute information pieces, and contains a plurality of type information pieces, each indicating a type of attribute information which differs from the others. Each of the plurality of first attribute control information pieces corresponds to the plurality of attribute information pieces, and each of the plurality of first attribute control information pieces contains first identification information indicating an association with one of the plurality of type information pieces.

Abstract: A three-dimensional data encoding method for encoding a target node included in an N-ary (N is an integer of 2 or more) tree structure of a plurality of three-dimensional points included in three-dimensional data comprises: encoding a first flag indicating whether or not to reference a node, the parent node of which is different from that of the target node (S3661); selecting, when the first flag indicates that the other node is referenced (Yes at S3662), an encoding table from N encoding tables in accordance with an occupied state of the target node in an adjacent node, and arithmetically encoding information on the target node by using the selected encoding table (S3663); and selecting, when the first flag indicates that the other node is not referenced (No at S3662), selecting an encoding table from M encoding tables different from N encoding tables in accordance with the occupied state of the target node in the adjacent node, and arithmetically encoding information on the target node by using the selected encoding table (S3664).

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).

Abstract: Se describe un método de codificación de imágenes incluye: (S141) realizar un procesamiento de SAO de muestras en una señal Y, una señal Cb y una señal Cr las cuales están incluidas en un bloque objetivo; (S142) realizar una codificación aritmética en un primer indicador (sao_merge_left_flag) que señala si un parámetro de SAO, el cual indica detalles del procesamiento de SAO, del bloque objetivo es idéntico o no a un parámetro de SAO para el bloque adyacente izquierdo inmediatamente a la izquierda del bloque objetivo; y (S144) realizar una codificación aritmética en el parámetro de SAO para el bloque objetivo, cuando el parámetro de SAO para el bloque objetivo es diferente del parámetro de SAO para el bloque adyacente izquierdo (No en S143). En la codificación aritmética en el primer indicador, un contexto individual se utiliza para realizar la codificación aritmética en el primer indicador para la señal de luminancia, la señal de crominancia Cb y la señal de crominancia Cr.

Abstract: This three-dimensional data encoding method comprises generating a plurality of frame data items by encoding point cloud data of a plurality of frames (S12021), and generating a bitstream containing the plurality of frame data items (S12022). Each of a plurality of processing unit data items includes a frame identifier indicating a frame to which the processing unit data belongs and a processing unit identifier indicating a processing unit corresponding to the processing unit data. The values of the plurality of frame identifiers corresponding to the plurality of frame data items arranged in the bitstream are set in a predetermined order. The values of the plurality of processing unit identifiers corresponding to the plurality of processing unit data items arranged in the frame data are set in an arbitrarily defined order.
