I have a 384*256 gray scale image which I partitioned into 24 equal size block. Now from these 24 blocks I want to reconstruct an image which is of same size as of input image but in which sequence of the blocks are different from the original block.

Now from these 24 blocks I want to reconstruct an image which is of same size as of input image but in which sequence of the blocks are different from the original block sequence i.e. for original block sequence are 1,2,3....24 but that sequence will not be same as this.

i have divided 384*256 image into 24 blocks each of size 64*64 so i have a 3-D array of size 64*64*24 where 24 denotes the block no. My question is I need to reconstruct a new image of size 384*256 in which these 24 blocks positions are shuffled according to a predefined sequence.

x = rand(64, 64, 24); % Example data
y = x(:, :, randperm(24));
Now the blocks are shuffled. How did you split the image into blocks? The reverse method creates an image again.
