Abstract: A method of correcting perspective distortion of a selfie image captured with a short camera-to-face distance by processing the selfie image and generating an undistorted selfie image appearing to be taken with a longer camera-to-face distance. A pre-trained 3D face GAN processes the selfie image, inverts the 3D face GAN to obtain improved face latent code and camera parameters, fine tunes a 3D face GAN generator, and manipulates camera parameters to render a photorealistic face selfie image. The processed selfie image has less distortion in the forehead, nose, cheek bones, jaw line, chin, lips, eyes, eyebrows, ears, hair, and neck of the face.
