Photos on the left are original, and the photos on the right are after the algorithm was applied.Ĭheckout more shots ( 167 images) right besides other methods to see the difference for yourself. Here are example photos fixed with the algorithm and they are incredible. Some devices may implement automatic distortion correction via CaptureRequest.DISTORTIONCORRECTIONMODE. For physical cameras, there are potentially very different lens configurations, especially on wide lenses.
They also mentioned that it gave good results when applied on the photos with a field-of-view (FOV) ranging from 70-degrees to 120-degrees. For logical cameras, the distortion is minimal and your application can use the frames more or less as they come from the camera. Researchers told that the algorithm is fast enough to work on on the smartphone “at an interactive rate”. It then reshapes the faces without effecting the other elements of the photo. This new method creates a content-aware warping mesh by detecting the areas of the frame with the faces. While the existing methods usually effect the backgrounds in the image. So the new method actually runs around the existing methods of and achieving all the good things. The paper also refers to the existing methods of correcting the distortion which somehow used to fix the faces but also introduce artifacts especially on the background. The have published a paper that elaborates the algorithm that fixes the effected photographs by only reshaping the faces and bodies but also adjusting the background and adjoining pixels. Thanks to a group of researchers at Google and MIT who have developed an efficient method to fix those images.
FRONT FACING CAMERA LENS DISTORTION SOFTWARE
Now there is a possible software solution to correct those photos artificially right on the smartphone. That’s what you usually refer to an unwelcomed effect of stretching, squishing or skewing – left photograph in the featured image above. So if those elements are faces of the people – close to the edges of the frame, they will be distorted as well. Wide-angle lenses will always distort the elements which are near the edges of the frame.
