Presenter(s):
Description:
GigaPan Stitch stitches together hundreds or thousands of overlapping images to create a very-high-resolution mosaic image. Without correction, such mosaics can be marred by vignetting (darkening of photographs in the lens periphery). Fortunately, it is possible to infer the vignetting attenuation function from the image overlaps and apply correction during blending. This workshop presents an algorithm for vignette correction that is fast, robust, and automatic.
