摘要： 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.

摘要： The present disclosure relates to an imaging processing apparatus and method by which degradation of the quality due to two-dimensional projection of 3D data can be suppressed.
All pieces of data for each position included in 3D data representative of a three-dimensional structure are projected to a two-dimensional plane of plural layers. Further, all pieces of data for each position of 3D data projected to a two-dimensional plane having the number of layers indicated by layer number information are projected to a three-dimensional space. The present disclosure can be applied, for example, to an information processing apparatus, an image processing apparatus, electronic equipment, an information processing method, and a program.-

摘要： The present disclosure relates to an image processing apparatus and a method that allow for easier and more appropriate rendering. Coded data is generated by encoding a two-dimensional plane image in which position information and attribute information for a point cloud that represents an object having a three-dimensional shape as a group of points are projected onto a two-dimensional plane, and a bitstream that includes the generated coded data and metadata to be used to render the point cloud is generated. The present disclosure can be applied to, for example, an image processing apparatus, an electronic device, an image processing method, a program, or the like.

摘要： There is provided an image processing apparatus and an image processing method that are capable of suppressing an increase in loads when a point cloud is generated from a mesh. Point cloud data is generated by positioning points at intersection points between a surface of a mesh and vectors each including, as a start origin, position coordinates corresponding to a specified resolution. For example, intersection determination is performed between the surface of the mesh and each of the vectors, and in a case where the surface and the vector are determined to intersect each other, the coordinates of the intersection point are calculated. The present disclosure can be applied to an image processing apparatus, electronic equipment, an image processing method, a program, or the like.

摘要： There is provided an information processing apparatus and an information processing method that can enhance the image quality while, at the same time, reducing increase in client's throughput. Image data of a plurality of projection directions is generated by projecting 3D data in a plurality of projection directions and converting the 3D data into two-dimensional data, and projection direction information indicating the projection direction of each piece of the image data is generated as projection metadata. Further, the projection direction information includes additional projection direction identification information that indicates that the image data has been generated by projection in additional projection directions. The present technology is applicable, for example, to a data generation apparatus that generates data for delivering a point cloud.

摘要： 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.

摘要： The present disclosure relates to image processing apparatus and method that can prevent a reduction in image quality. Geometry data that is a frame image having arranged thereon a projected image obtained by projecting 3D data representing a three-dimensional structure on a two-dimensional plane and includes a special value indicating occupancy map information in a range is generated. The generated geometry data is encoded. Further, the encoded data on the geometry data is decoded, and a depth value indicating a position of the 3D data and the occupancy map information are extracted from the decoded geometry data. The present disclosure is applicable to, for example, an information processing apparatus, an image processing apparatus, electronic equipment, an information processing method, or a program.

摘要： 3D data representing a three-dimensional structure is divided into a plurality of pieces and encoded, an obtained plurality of divided bitstreams is multiplexed, and one bitstream including a separator indicating a position of a joint between the divided bitstreams is generated. Furthermore, a separator indicating a position of a joint between divided bitstreams obtained by dividing 3D data representing a three-dimensional structure into a plurality of pieces and encoding the plurality of divided pieces of the 3D data, which is included in a bitstream obtained by multiplexing a plurality of the divided bitstreams, is analyzed, and the bitstream is divided into every divided bitstream on the basis of information included in the analyzed separator, and decoded. Applications of the technology include being implemented in, for example, an information processing apparatus, an image processing apparatus, electronic equipment, an information processing method, a program, or the like.
