Patent ID: 10762667

Abstract:
A method for point cloud coding (200 or 300) or decoding (400 or 500) includes identifying (201) a plurality of quantized points in 3D space, defining (202), a sequence order of the quantized points in 3D space, and identifying (203) differential vector patterns in the sequence order of quantized points in 3D space. The method further includes identifying (204) Morton Index Differences in the sequence order of quantized points in 3d space, coding (205) the one or more quantized points in 3D space using differential vector patterns in a first plurality of codewords, coding (206) the one or more quantized points in 3D space using the Morton index differences in a second plurality of codewords, combining (207) the first and second plurality of codewords into a third plurality of codewords, and coding (208) the third plurality of codewords using an entropy coding scheme into a bitstream.
