Abstract
When photographs are to be combined into a single image, haze correction and/or color balancing may be performed. The photographs may be analyzed and left-clipped in order to darken the photographs and to increase the density of pixels in the low-luminosity region, thereby decreasing the perception of haze. When the photographs are combined into one continuous image, tie points are selected that lie in regions where the photographs overlap. The tie points may be selected based on visual similarity of the photographs in the region around the tie point, using a variety of algorithms. Functions are then chosen to generate saturation and luminosity values that minimize, at the tie points, the cost of using the generated values as opposed to the actual saturation and luminosity values. These functions are then used to generate saturation and luminosity values for the full image.
