Everyone tries to take photos without getting their reflection in the shot, whether in front of a window, a picture of a computer screen, etc. Unfortunately, unless you are taking these photos from an odd angle, you never can seem to get yourself out of the shot. But, now maybe you can.Researchers from the Massachusetts Institute of Technology might have a solution for this. Using the fact that photos taken through double-pane glass windows nearly always contain two almost identical, slightly shifted reflections, the team, led by YiChang Shih, have developed an algorithm that can automatically remove the unwelcome “ghosted” element from a digital photo.
The algorithm, building on work done by Daniel Zoran and Yair Weiss of the Hebrew University of Jerusalem, divides images into 8-by-8 blocks of pixels and determines each pixel’s correlation with another. Their technique is able to identify which minuscule sections of the photo are part of the reflection and which are the actual image seen behind the glass.
“The ideas here can progress into routine photography, if the algorithm is further robustified and becomes part of toolboxes used in digital photography,” Yoav Schechner, a professor of electrical engineering at Israel’s Technion, said in a statement from MIT. He also suggested that with refinement, the software could help robot vision determine whether it is seeing a reflection or through glass.

I write like I think—fast, curious, and a little feral. I chase the weird, the witty, and the why-is-this-happening-now. From AI meltdowns to fashion glow-ups, if it makes you raise an eyebrow or rethink your algorithm, I’m probably writing about it. Expect sharp takes, occasional sarcasm, and zero tolerance for boring content.
