Abstract:
A point cloud encoder including an input interface to accept a dynamic point cloud including a sequence of point cloud frames of a scene. A processor encodes blocks of a current point cloud frame to produce an encoded frame. Wherein, for encoding a current block of the current point cloud frame, a reference block is selected similar to the current block according to a similarity metric to serve as a reference to encode the current block. Pair each point in the current block to a point in the reference block based on values of the paired points. Encode the current block based on a combination of an identification of the reference block and residuals between the values of the paired points. Wherein the residuals are ordered according to an order of the values of the points in the reference block. A transmitter transmits the encoded frame over a communication channel.

Claim (Index 9):
The encoder of  claim 1 , wherein, to encode the current block, the hardware processor is configured to:\n construct a nearest neighbor graph representing the points of the reference block, such that each paired point in the reference block is a node in the nearest neighbor graph; perform an eigen-decomposition of the nearest neighbor graph to produce a graph transform operator; transform the residuals using the graph transform operator to produce graph transform coefficients; and quantize and entropy code the graph transform coefficients.
