Watermarking, as opposed to steganography, has an additional requirement of robustness against possible attacks. An ideal steganographic system would embed a large amount of information perfectly securely, with no visible degradation to the cover object.

bpsk modulation is done using simulink model in this document. hope u get knowledge

对椒盐噪声和噪声分别进行3种滤波,包括算术均值滤波、几何均值滤波、中值滤波(three kinds of filter to salt and pepper noise and gaussian noise ,including arithmetic mean filter, geometric mean filter, median filter)
