Abstract
An image transformation method includes: causing a first display device to display one or more calibration patterns. One or more first images include a corresponding calibration pattern of the one or more calibration patterns. The one or more first images are captured by an image capture device disposed at a non-zero capture angle with respect to the first display device. The method also includes determining based on the one or more first images, a transformation to be applied to account for the non-zero capture angle; obtaining a second image of a human user; applying the transformation to the second image to generate a transformed spoof representation of the human user for capture by the image capture device being held at the non-zero capture angle with respect to the first display device; and causing the first display device to display the transformed spoof representation.
