Abstract
Provided are a method and an apparatus for selectively encoding/decoding point sequences to maximize bit efficiency of a lightweight application scene representation (LASeR) binary stream. The point sequence encoding method includes the steps of: for each point sequence, (a) selecting one of exponential-Golomb (EG) encoding and fixed length (FL) encoding schemes; (b) when the FL encoding scheme is selected, encoding the point sequence using the FL encoding scheme to generate a binary stream; and (c) when the EG encoding scheme is selected, encoding the point sequence using the EG encoding scheme to generate a binary stream. The binary stream includes a flag indicating which encoding scheme is selected and a parameter k, with which the EG encoding can be most effectively performed, when the EG encoding scheme is selected. According to the encoding method, LASeR point sequences can be efficiently encoded and, during a decoding process, a large overhead is not incurred to a decoder (terminal).
