Item Analyzing the Behavior of Projector-Camera Systems Based on Reaction-Diffusion Equations(The Eurographics Association, 2023) Amano, Toshiyuki; Jean-Marie Normand; Maki Sugimoto; Veronica SundstedtPixel Feedback Animation (PFA), a technique that uses projector-camera feedback, has emerged as a dynamic illumination method introducing variations in color and brightness for expressive purposes. Notably, the deliberate application of specific image processing techniques during the projector-camera feedback loop has unveiled the potential to generate patterns reminiscent of Turing patterns solutions to reaction-diffusion equations. However, the intrinsic nature of PFA's projection-camera system consists of image capture and reflective properties of the projection surface, which create illumination patterns. In this paper, a comprehensive investigation into the underlying mechanisms of PFA is presented, revealing its inherent connection to reaction-diffusion systems. The study explores the emergence of distinct PFA patterns intricately influenced by variations in object surface reflectivity and coloration.
