Abstract: 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.

Abstract: The present disclosure relates to an image processing apparatus and an image processing method that enable to suppress an increase in processing time of a filter process for point cloud data.
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: 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.
