Abstract: The present disclosure relates to information processing apparatus and method that makes it possible to suppress a reduction in encoding efficiency. Information relating to quantization of a three-dimensional position of an encoding target is generated. For example, the information relating to the quantization includes information relating to a coordinate system to be subjected to the quantization, information relating to a bounding box for normalization of position information of the encoding target, or information relating to a voxel for quantization of position information of the encoding target. In addition, three-dimensional information of the encoding target is restored from a signal string on the basis of the information relating to the quantization of the three-dimensional position of the encoding target. The present disclosure is applicable to, for example, an information processing apparatus, an image processing apparatus, an electronic device, an information processing method, a program, or the like.

Abstract: There is provided an encoding apparatus and an encoding method that make it possible to generate an encoded stream from which an image of a low load and high picture quality can be decoded. An arithmetic operation section or the like divides an image into a plurality of AUs and encodes the AUs to generate encoded streams of the plurality of AUs. A setting section sets 0 as pic_output_flag indicating that a decoded image obtained by decoding an encoded stream of an AU other than the last division AU from among the encoded streams of the plurality of AUs generated by the arithmetic operation section or the like is not to be displayed. The present disclosure can be applied, for example, to an encoding apparatus and so forth.

Abstract: There is provided an image processing device and a method that enable partial decoding of 3D data to be performed more easily. 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 method that make it possible to decode encoded data of 3D data with increased ease.
A bit stream is generated which includes projection direction information including information relating to a projection direction of position information of 3D data representative of a three-dimensional structure on a two-dimensional plane and encoded data of a geometry image obtained by projecting the position information on the two-dimensional plane. The present disclosure can be applied, for example, to an information processing apparatus, an image processing apparatus, electronic equipment, an information processing method, a program, or the like.

Abstract: The present disclosure relates to an information processing apparatus and a method that allows for suppression of a decrease in encoding efficiency. In comparison of voxel data resulting from quantization of point cloud data, a correlation degree of a distribution pattern between voxel data to be compared is calculated on the basis of a subjective feature of the distribution pattern of values of the voxel data. The present disclosure is applicable to an information processing apparatus, an image processing apparatus, an electronic device, an information processing method, a program, or the like, for example.
