frame averaging

Frame averaging is a technique used in imaging and video processing to improve image quality by reducing noise. It involves combining multiple consecutive frames—essentially taking several pictures in quick succession—and averaging their pixel values. This process smooths out random fluctuations or graininess in the images, resulting in a clearer, more stable picture. Frame averaging is particularly useful in low-light conditions or scientific imaging, where it helps reveal details that might otherwise be obscured by noise, improving overall clarity without increasing exposure time or brightness.
