Please post any details. Explain the available inputs, the wanted algorithm and parameters as well as the wanted output. If you do noit know the algorithm, give us enough details of the wanted transformation, that we can determine the necessary algorithm uniquely.

Try imresize or something like this

subsampledImage = fullImage(1:2:end, 1:2:end);
