I am applying arnold transform method on an image to scramble its pixels. And i am doing it successfully but the problem in this method is that first I have to binarize the image before applying this method and that is why I am getting binarized image in a result in inverse of arnold transform. So, my question is that is there any other method in which I scramble or shuffle pixels by setting a key value without binarizing the image? so that I would be able to revert the image back ?
thank you very much :-)
