Abstract
A method and apparatus is provided for efficiently and automatically removing unwanted temporal lighting variations from image sequences. Specifically, temporal light variations from a sequence of images are removed by a process of selecting a reference image (R) and designating a portion of the reference image as a reference image region (M), designating a first portion of at least one base image (F) of the sequence of images as a first selected image region (M') and a second portion as a second selected image region (M'), generating a color mapping by comparing the selected image region of the base image (M') with the reference image region of the reference image frame (M), and applying the color mapping to the second selected image region (M') of the base image (F) to generated a corrected image (F'). Three separate methods of performing the color mapping are disclosed.
