    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: 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.

    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: 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.
