Abstract
Systems and methods for adjusting an exposure parameter of an imaging device are disclosed. A first exposure level of the imaging device is identified, and a first image of a scene is captured via the imaging device at the first exposure level. The first image of the scene comprises a plurality of polarization images corresponding to different degrees and angles of polarization. Each of the polarization images comprise a plurality of color channels. A gradient for the first image is computed based on the plurality of the polarization images, and a second exposure level is computed based on the gradient. A second image of the scene is captured based on the second exposure level, where the gradient of the second image is greater than a gradient for the first image.
