Is there a way to do that using the code provided by 5: It should be ok with this function: So I solved a problem but actually there's a problem within the function: it doesn't scramble pixels, it scrambles values generating colors that were not in the original picture.ĮDIT 3: I used the code provided by and I obtain exactly what I need, thanks!ĮDIT 4: Ok, turns out it's not ok to scramble the pixels since it makes the image too scattered and different from the starting image (you don't say?), but I need to scramble BLOCKS OF PIXELS so that you can't really recognize the image but the black pixels are not too scattered. So I checked the scrambled image, and the function from the FEX file actually scrambles within the RGB values, meaning that I found, for instance, a pixel with RGB 0,255,0. This is the BW picture I start with: BW IMAGE. It works, but what I obtain is the following image: SCRAMBLED IMAGE. I think the different data format (logic vs integer) is what yields errors when using the function for RGB images.ĮDIT 2: I adapted the demo code from the aforementioned package and I used the suggestion by for transforming a 2D matrix into a 3D matrix, and added a loop to transform the logic values into RGB integer values, then use the imScrambleRand function. Is there a way to transform b&w images into 3D matrices so that I can use that function? Or can anyone suggest any other script that does what I need? Keep in mind that I'm not familiar with Matlab, but I'll do my best.ĮDIT 1: When I import the BW image I get a 2D matrix of logic values (0 = black, 1 = white). I found this package in Mathworks File Exchange ( ) one of the functions, imScrambleRand, does exactly what I need, but it works for RGB images (3D matrices).
