METHOD AND DEVICE FOR COMPRESSION OF BINARY SEQUENCES BY GROUPING MULTIPLE SYMBOLS |
摘要 |
<p>A method for encoding an input sequence of symbols to produce a bitstream and a method of decoding the bitstream to generate a reconstructed binary sequence. Encoding employs 2L-ary encoding trees having codewords associated with leaf nodes. A context model is used to select an encoding tree corresponding to an estimated probability at the encoder. The same context model is used by the decoder to select a decoding tree. The decoder interleaves bits from decoded sequences of length-L strings associated with different estimated probabilities, based on the context model.</p> |
