Abstract
Among other things, one or more techniques and/or systems are provided for quantifying blur of an image. Blur may result due to motion of a camera while the image is captured. Accordingly, motion measurement data corresponding to motion of the camera during an exposure event may be used to create a camera rotation matrix. A camera intrinsic matrix may be obtained based upon a focal length and principle point of the camera. A transformation matrix may be estimated based upon the camera rotation matrix and/or the camera intrinsic matrix. The transformation matrix may be applied to pixels within the image to determine a blur metric for the image. In this way, blur of an image may be quantified offline and/or in real-time during operation of the camera (e.g., so that the image may be re-acquired (e.g., on the fly) if the image is regarded as being overly blurry).
