The image undergoes first-level DWT decomposition, where two uncorrelated pseudo-random sequences represent 0 and 1 in the watermark information, embedded into the LH and HL subbands of the wavelet decomposition. Note: The complete algorithm consists of two parts: watermark embedding and watermark extraction.
