Coded aperture is very interesting, but while it has less mechanical cost without a lens, images will be of lower resolution and more noisy, due to non-uniform power spectral density of the aperture, so the deconvolution (or equalization) will make the more attenuated frequencies noisy. That's why the researchers cite applications that don't require human examination of the photograph.
