This topic is based on MATLAB wavelet transform DWT and discrete cosine DCT multi method comparison digital watermarking system. With GUI interface. There is a main interface GUI, which can call the sub interface of DWT method and DCT method. The process includes: reading host image and watermark image, embedding, attack of various methods (cutting, adding noise, rotation, etc.), extracting, and finally evaluating the robustness of different attacks by using PSNR peak signal-to-noise ratio.
