  We present a novel method for the interactive control of geometric
abstraction and texture in artistic images. Previous example-based stylization
methods often entangle shape, texture, and color, while generative methods for
image synthesis generally either make assumptions about the input image, such
as only allowing faces or do not offer precise editing controls. By contrast,
our holistic approach spatially decomposes the input into shapes and a
parametric representation of high-frequency details comprising the image's
texture, thus enabling independent control of color and texture. Each parameter
in this representation controls painterly attributes of a pipeline of
differentiable stylization filters. The proposed decoupling of shape and
texture enables various options for stylistic editing, including interactive
global and local adjustments of shape, stroke, and painterly attributes such as
surface relief and contours. Additionally, we demonstrate optimization-based
texture style-transfer in the parametric space using reference images and text
prompts, as well as the training of single- and arbitrary style parameter
prediction networks for real-time texture decomposition.
