Dear List, I am looking to find a method for correcting vignetting occurring in HDR images using radiance as part of an undergraduate research study. I am using a Uniform Luminance Sphere to create a uniformly lit background in order to create a reference image.
I have used radiance to create the HDR images, and I am wondering if there is a way to take the HDR image and divide each pixel intensity by that of its optical center. This would create an image/mask of fractional pixel values that can be divided into another image to correct for the cameras specific vignetting. Other suggestions would be greatly appreciated as well. Thanks, Josh -- *Joshua Wilson* 4th year Architectural Engineering Student (Lighting/Electrical) Durham School of Architectural Engineering and Construction UNL College of Engineering (Omaha Campus) [email protected]
