Abstract
Image processing systems and methods are disclosed, including an image processing system comprising a computer running image processing software causing the computer to divide a captured oblique image into a plurality of oblique image sections, the oblique image sections determined at least in part on a path length distance between the location of a point in the scene in the captured oblique image and the location of the camera when the oblique image was captured; and apply a varying amount of color correction to the sections based in part on the determined path length, thereby reducing variation in the captured oblique image caused by specular reflection and atmosphere depicted in the sections prior to color balancing.
