摘要
preferably at least one image in respect of the high frequency sub-band (sub-band) for the integer wavelet transform ( integer wavelet transform, IWT) providing a block of coefficients; Determining an average value of the block in the coefficient; And the encoding (encode) a method which comprises the step of logically (logical) 0 and the logical bit value (logical) 1 bit of embedded one (embed) in the first block by setting the average value is provided.
