MATLAB training program (Hilbert image scrambling) has just written a Hibert-curve, than add a review application process. About Hilbert image scrambling, I searched on the Web application focuses on digital watermarks and encryption, which I haven't touched in two areas. Most image scrambling is scrambling 1 shown in the following illustration, 2 is I accidentally generated as scrambling. Shuffle 1 is to extend the original assignment by Hilbert curve, pull into a one-dimensional array, and then reshape it into an image. Scramble 2 is to reshape into a one-dimensional array of artwork, and then the Hilbert curve value, generating a pair of images. I feel like almost, 1 online scrambling a little more common, scrambling 2 seemed to be seen, but it is scrambled. Scrambling 1 can also be used to generate an image, then scrambling for Figure 2 generated recycled into an image, it would be an even bigger mess, but also is able to recover the original image again.
