Management information of a block as a partial region in a predetermined three-dimensional spatial region including 3D data representing a three-dimensional structure is generated. In addition, a block satisfying a condition specified by a user is selected on the basis of management information of the block as a partial region in a predetermined three-dimensional spatial region including 3D data representing a three-dimensional structure, and coded data of the 3D data within the selected block is decoded. The present disclosure can be applied to, for example, an image processing device, an electronic apparatus, an image processing method, a program, or the like.

Abstract: The present disclosure relates to an image processing apparatus and a method that enable decoding of encoded data of an octree in various processing orders. The octree corresponding to point cloud data is encoded after the context is initialized for each layer of the octree. Further, a breadth-first order or a depth-first order is selected as the decoding order for the encoded data of the octree corresponding to point cloud data, and the encoded data is decoded in the selected decoding order. The present disclosure can be applied to an image processing apparatus, an electronic apparatus, an image processing method, a program, or the like, for example.

Abstract: A filter process is performed on point cloud data using a representative value of the point cloud data for each local region obtained by dividing a three-dimensional space. A two-dimensional plane image on which the point cloud data subjected to the filter process is projected is encoded, and a bitstream is generated. The present disclosure can be applied to, for example, an information processing apparatus, an image processing apparatus, electronic equipment, an information processing method, a program, or the like.

Abstract: A video processing apparatus includes a combining unit that combines encoded streams of a plurality of videos to generate an encoded stream of a multiple-video image composed of the videos, each encoded stream of each video having coding units in each horizontal line that are encoded as a slice, and an insertion unit that inserts an insertion stream into the encoded stream of the multiple-video image generated by the combining unit when a view area of the multiple-video image is moved. The insertion stream is an encoded stream in which all the coding units in the multiple-video image are replaced with skip macroblocks with a motion vector indicating a direction and an amount of movement of the view area.

Abstract: The present disclosure relates to an information processing apparatus and method that are capable of suppressing a decrease in encoding efficiency. When point cloud data is to be Octree-encoded, a point distribution of child nodes of a current node is updated in accordance with a peripheral point distribution around the current node, and then a sequence of signals is generated by performing Octree encoding with the updated point distribution. The present disclosure is applicable, for example, to information processing apparatuses, image processing apparatuses, electronic equipment, information processing methods, or programs.
