%X According to the features of steganography,a new extraction was proposed.Different from the traditional extraction based on the invert embedding,this new extraction used FastICA to separate the cover image and embedded image.The objects which have been treated with were wavelet coefficients of true color picture,so steganography,wavelet and Independent Component Analysis(ICA) were combined together.The effect of algorithm proves that ICA can not only be used as extraction but also extract the embedded image blindly.
