>You arbitrarily picked 16 possible photorealistic faces out of a total solution space of what? Millions? Wouldn't the solution be to find a 4 different axes and pick faces that represent different endpoints. With a little psychology to help us identify what features are best to inform the public of we should be able to create a collection of photos that will be more likely to result in someone identifying the suspect than either the single photo option or the photo collection option. We would still need to test to see if it is better than the single lower quality photo option.
