Face depixelizer with machine learning, and some assumptions

In crime shows, they often have this amazing tool that turns a low-resolution, pixelated image of a person’s face to a high-resolution, highly accurate picture of the perp. Face Depixelizer is a step towards that with machine learning — except it seems to assume that everyone looks the same. There might still be some limitations. Tags: bias, face, pixels

Reconstructing faces from brain waves

Researchers attached electrodes to neurons in monkeys, showed them pictures of faces, and then reconstructed the faces reading brain waves. After decades of work, scientists at Caltech may have finally cracked our brain’s facial recognition code. Using brain scans and direct neuron recording from macaque monkeys, the team found specialized “face patches” that respond to specific combinations of facial features. Like dials on a music mixer, each patch is fine-tuned...

DNA face estimation

Parabon NanoLabs is working on a service that provides face estimates using DNA found at crime scenes. Pretty cool. But, before anyone gets too excited, keep in mind that the estimates are still really rough. Greytak agrees Snapshot is not super-precise, nor is the science ready for it to be. "Our goal is not to produce a profile that is perfectly accurate and there is only one person you've ever...
