Hi there,
Although I am able to successfully scramble entire images (using JigSaw.m, or RANDBLOCK.m), I cannot figure out how to scramble specific matrix elements within each image. I have attached 'before' and 'after' images showing precisely what I wish to achieve.
The first image is divided into an 8 x 7 matrix, and specific elements (i.e.,1,1;1,2;1,3;1,4;1,5;2,1;2,2;2,3;2,4;2,5;3,1;3,2;3,3;3,4;3,5;4,2;4,3;4,4;5,2;5,3;5,4;6,2;6,3;6,4) are then scrambled to produce the second image.
I would be ever so grateful for any advice, as am a novice to Matlab, and need to complete the stimuli asap!
Kindest regards
Maria
