Google Creates Algorithm to Eliminate Face Distortions in Photos

Shooting with wide-angle lenses delivers stunning pictures in terms of the perspective, but there is a risk that the faces of people captured will be stretched. It happens particularly often when lenses are installed for widescreen images on smartphones. Google’s new algorithm is designed to correct possible distortions.

Usually, such distortions can be corrected using filters, but by correcting faces, they distort perspective lines in the entire image making background objects unnaturally bended.

Google has already developed a method to correct distortions of the faces captured without affecting the background. It involves the processing of both people and objects.

To do that, the system determines the objects shown separating faces from backgrounds. This is how a photo perspective correction map is formed, but it applies only to certain areas. Straight lines of the perspective remain intact, although people’s faces get shifted.

Despite the complexity, the algorithm works quickly emphasizing its high status.
