A method for encoding at least one block of pixels, includes the steps of: transforming pixel values for said block into a set of coefficients each having a coefficient type; determining an initial coefficient encoding merit for each coefficient type; quantizing, into quantized symbols, only coefficients for which the initial coefficient encoding merit is greater than a predetermined block merit; and encoding the quantized symbols into encoded data. Corresponding decoding methods, encoding and decoding devices are also proposed.
