PatternPortrait: Draw Me Like One of Your Scribbles
Sabine Wieluch Friedhelm Schwenker
This paper introduces a process for generating abstract portrait drawings
from pictures. Their unique style is created by utilizing single freehand
pattern sketches as references to generate unique patterns for shading. The
method involves extracting facial and body features from images and
transforming them into vector lines. A key aspect of the research is the
development of a graph neural network architecture designed to learn sketch
stroke representations in vector form, enabling the generation of diverse
stroke variations. The combination of these two approaches creates joyful
abstract drawings that are realized via a pen plotter. The presented process
garnered positive feedback from an audience of approximately 280 participants.
