Title:
IMAGE PROCESSING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2021/095565
Kind Code:
A1
Abstract:
The present disclosure pertains to an information processing device and an information processing method which enable suppression of any reduction in the subjective quality of a point cloud. In the present disclosure, decoding is performed on encoded data of a frame image in which an image projected onto a two-dimensional plane of a point cloud expressing an object of three-dimensional shape as a set of points is disposed, the frame image obtained by decoding the encoded data is unpacked to extract the projection image, the points included in the extracted projection image are disposed in a three-dimensional space, and, when the coordinates of the points are not integer values in a basic coordinate system that is a predetermined coordinate system of the three-dimensional space, the points are moved in a direction perpendicular to the two-dimensional plane such that the coordinates of the points become integer values, whereby the point cloud is reconstructed. The present disclosure may be applied, for example, to an image processing device, an electronic device, an image processing method, a program, or the like.
