  • Publication number: 20220303578
    Abstract: There is provided an image processing apparatus and a method designed to be capable of reducing degradation of the subjective quality of a point cloud. Encoded data of a frame image in which a projection image of a point cloud representing a three-dimensional object as a set of points on a two-dimensional plane is placed is decoded, the frame image obtained by decoding the encoded data is unpacked to extract the projection image, and the respective points included in the extracted projection image are arranged in a three-dimensional space. When the coordinates of a point are not integer values in a basic coordinate system that is a predetermined coordinate system of the three-dimensional space, the point is moved in a direction perpendicular to the two-dimensional plane so that the coordinates of the point become integer values. Thus, the point cloud is reconstructed.

    Abstract: The present disclosure relates to an information processing device and method capable of curbing reduction in encoding efficiency. In an information processing device for processing attribute information of each point of a point cloud representing an object in a three-dimensional shape as a set of points, a first level is hierarchized using a first hierarchization method and a second level different from the first level is hierarchized using a second hierarchization method different from the first hierarchization method at the time of performing hierarchization of attribute information by recursively repeating processing of, among points classified as a predictive point or a reference point, deriving a difference value between a predictive value of attribute information of the predictive point derived using attribute information of the reference point and the attribute information of the predictive point for the reference point to perform hierarchization of the attribute information.
