SplitImage = reshape(Image, 16, 20, 16, 15);
SplitImage = permute(SplitImage, [1, 3, 2, 4]);
SplitImage = reshape(SplitImage, [16, 16, 300]);

SplitImage = mat2cell(Image, 16 * ones(1, size(Image,1) / 16), 16 * ones(1, size(Image,2) / 16), size(Image,3));

Glad it does what you want, though if speed was your goal, Jan's method is about 4 times faster.
