Variance image from video of beach in Madeira Beach, Florida

Image in mostly black and gray tones showing distant view of beach stretching from bottom left to upper right of photo.

Detailed Description

“Variance” image produced from video shot at Madeira Beach, Florida, on June 20, 2017. The more the light intensity changes at a given spot, or “pixel,” during the video, the brighter the value assigned to that pixel. Motion tends to produce changes in light intensity. Note bright bands parallel to shore where waves were breaking. Researchers are using these and other video images to improve understanding and computer modeling of beach processes, especially those that change the coast.
