Abstract
There is provided an information processing device and method capable of suppressing a reduction in encoding efficiency. When performing, for attribute information of each point of a point cloud that represents an object having a three-dimensional shape as a set of points, hierarchization of the attribute information by recursively repeating classification of a prediction point for deriving a difference value between the attribute information and a predicted value of the attribute information and a reference point used for deriving the predicted value with respect to the reference point, the reference point is set on the basis of a centroid of points. The present disclosure can be applied to, for example, an information processing device, an image processing device, an encoding device, a decoding device, an electronic device, an information processing method, a program, and the like.
