Abstract: An image processing apparatus and a method comprises generating a video frame that includes a patch obtained by projecting, onto a two dimensional plane, a point cloud that represents an object having a three-dimensional shape as a group of points; generating a thumbnail two-dimensional image, the thumbnail two-dimensional image being generated independently from the patch; embedding the thumbnail two-dimensional image into the video frame; and encoding the video frame to generate a bitstream.

Abstract: There is provided an information processing apparatus and method that makes it possible to suppress a reduction in a subjective image quality. Point cloud data before update of position information is searched for a point to be compared, the point to be compared being a point to be compared with a current point, the current point being a processing target point of the point cloud data with the updated position information, and the retrieved point to be compared is compared with the current point, and attribute information of the current point is set. The present disclosure is applicable to, for example, an information processing apparatus, an image processing apparatus, electronic equipment, an information processing method, a program, etc.

Abstract: The present disclosure relates to an information processing apparatus and an information processing method capable of suppressing a reduction in quality of rendering results. Rendering is performed on voxel data that is 3D data obtained by quantizing position information using voxels and representing a three-dimensional structure in response to a shape of each of the voxels. Alternatively, rendering is performed on voxel data that is 3D data obtained by quantizing position information using voxels and representing a three-dimensional structure on the basis of rendering information that is information related to the rendering of the voxel data. The present disclosure is applicable to, for example, an information processing apparatus, an image processing apparatus, an electronic apparatus, an information processing method, a program, and the like.

Abstract: An information processing device and method for enabling partial control of the resolution of a data group that can be turned into a tree structure. Data of an Octree pattern is encoded, so that a bit stream containing depth control information indicating that a leaf node is to be formed at a different level from the lowest level based on information specifying the depth of the Octree pattern is generated. Also, a bit stream is decoded, so that an Octree pattern including a leaf node at a different level from the lowest level is constructed, on the basis of depth control information indicating that the leaf node is to be formed at a different level from the lowest level based on information specifying the depth of the Octree pattern. The present disclosure can be applied to an information processing device, an image processing device, an electronic apparatus, an information processing method, a program, or the like, for example.
