MATLAB: Grouping small pixels to make larger usable cells.

arraycellscellular automataImage Processing ToolboxMATLABpixels

I have a simple rgb array of no more than 5 distinct colours. I wish to apply cellular automata to this array, however I cannot as the pixels are way to small to act as my cells. Is there any way to group, lets say, 20 x 20 pixels to represent one cell for my cellular automata?

Try superpixels(). Or try my attached RGB classifier demo. Or try my blockproc() demo.

Hi Praveen,

NCA functionality in SimBiology currently doesn't support infusion dosing.

MATLAB: Grouping Data Into Smaller “Bins”

G   = rand(5000, 3);  % "data points" is not clear
N   = 100;
siz = size(G);
GG  = reshape(G, [N, siz(1)/N, siz(2)]);
R   = reshape(sum(GG, 1) / N, siz(1)/N, siz(2));

If the length of the first dimension is not a multiple of N, you might want to crop the input at first.

R = BlockMean(G, N, 1) / N;
