Image acquisition and normalization process. First, after the subject took the shot, the rectangular region (outlined in blue) was cropped and stored. Then, the images were normalized in terms of rotation and scale using the manual annotations of the corners of the eyes. Lastly, the normalized images were cropped, generating the periocular regions of the left and right eyes.
