Description: Information embedded in the DCT coefficients of the image, the image of the common 512* 512 size gray-scale (experimental image LENA.BMP).Information embedded as a binary Logo Figure (experiment with the logo picture shows the LOGO.bmp), the plot size is 64* 64, a total of 4096 Bit.
(1) the use of the STDM method watermarked LENA Figure, output embedded watermark image.
(2) logo watermark image decoding, the output decoded Figure statistical error rate.
