Abstract
A method for encoding and decoding an input signal, includes the following steps: applying a transform to the input signal to obtain a transformed signal; quantizing the transformed signal to obtain a sequence of quantized values, the quantized values being representable in the form of ordered binary bits; for each order of said binary bits, encoding a bit plane of the sequence using (run, end) coding to obtain encoded values; and decoding the encoded values to recover the input signal.
