Item Art-directable Stroke-based Rendering on Mobile Devices(The Eurographics Association, 2023) Wagner, Ronja; Schulz, Sebastian; Reimann, Max; Semmo, Amir; Döllner, Jürgen; Trapp, Matthias; Guthe, Michael; Grosch, ThorstenThis paper introduces an art-directable stroke-based rendering technique for transforming photos into painterly renditions on mobile devices. Unlike previous approaches that rely on time-consuming iterative computations and explicit brush-stroke geometry, our method offers a interactive image-based implementation tailored to the capabilities of modern mobile devices. The technique places curved brush strokes in multiple passes, leveraging a texture bombing algorithm. To maintain and highlight essential details for stylization, we incorporate additional information such as image salience, depth, and facial landmarks as parameters. Our technique enables a user to control and manipulate using a wide range of parameters and masks during editing to adjust and refine the stylized image. The result is an interactive painterly stylization tool that supports high-resolution input images, providing users with an immersive and engaging artistic experience on their mobile devices.
