– most modern datasets are static. The recent CelebA-Aging dataset is synthetic; LFW has only a handful of repeat subjects. For aging research, Morph II remains gold standard.
If you plan to use Morph II in your work, do so with transparency. Acknowledge its biases. Report performance not just overall but across demographic subgroups. Consider whether a synthetic or augmented version could reduce harm. And always remember: behind each of those 55,000 images is a person who volunteered for science, not for surveillance. morph ii dataset
