"NUCA is a speculative design and art project by Mathias Vef and Benedikt Groß. The project aims to provoke and question the current trajectory of generative AI in reproducing body images."

"The current NUCA prototype is a 3d-printed camera (19.5 × 6 × 1.5 cm, 430g). The device is equipped with a 37 mm wide angle lens and an ergonomic grip. The viewfinder displays the input image and can be configured to show some of the input parameters e.g. pose detection in real-time. By pressing the trigger, the camera will create an estimated natural nude representation of the person being photographed. The inputs of the generative image process are the photo, the person’s pose (estimated skeleton) and the landmarks of the person’s face. The input photo is being analyzed by a custom classifier on 45 identifiers on gender, age, ethnicity, expression, hair, glasses, body shape etc. These ratings are then being used to generate a base image by formulating a prompt for a text-to-image AI (Stable Diffusion). The base image is a generic estimation of a nude person fulfilling this prompt. In the last step the image is then being individualized by taking the person’s face and pose into account in the final development of the nude portrait."
