divide image into block of size 1*2

I have a 512*512 image and I want to divide into blocks each having 1x2 pixels.So I will get total 131072 blocks.Now I want to process each blocks.

i am doing in matlab code.. Any idea?

[Walter Roberson]

image_blocks = num2cell(TheImage);

Now image_blocks{J,K} will be the 1 x 1 block corresponding to the pixel at TheImage{J,K}

I cannot think of any advantage of dividing into 1 x 1 blocks, unless perhaps it is for convenience in holding the bit equivalent as a unit ? But if that is the situation then

bit_cells = arrayfun(@(V) dec2bin(V,8), TheImage, 'Uniform', 0);

Thank you Mr. Walter Roberson ..you are right..no use of 1*1..BUT IF I WANT TO DO 1*2 PIXELS IN A BLOCK..THEN HOW CAN I

image_blocks = mat2cell(TheImage, ones(1,size(TheImage,1), 2 * ones(1, size(TheImage,2)/2) );
