Abstract
A method is presented for reducing glare in images captured by an imaging system. As a starting point, multiple images of a scene are captured by an imaging system to form a set of images, where the imaging system includes a voltage tunable polarizer and each image in the set of images is captured with the voltage tunable polarizer set at a different polarization angle. The method further includes: partitioning each image in the set of images into a plurality of segments; for corresponding segments in the set of images, determining an amount of change in intensity across corresponding segments of images; quantifying the amount of intensity change for each image in the set of images; and identifying a given image from the set of images based on the quantified amount of intensity change, where the given image has least amount of intensity change amongst the set of images.
