abstract = {In this paper, we propose an interactive system for generating
artistic sketches from images, based on the stylized
multiresolution B-spline curve model and the livewire contour
tracing paradigm. Our multiresolution B-spline stroke model allows
interactive and continuous control of style and shape of the
stroke at any level of details. Especially, we introduce a novel
mathematical paradigm called the wavelet frame to provide
essential properties for multiresolution stroke editing, such as
feature point preservation, locality, time-efficiency, good
approximation, etc. The livewire stroke map construction leads the
user-guided stroke to automatically lock on to the target contour,
allowing fast and accurate sketch drawing. We classify the target
contours as outlines and interior flow, and develop two respective
livewire techniques based on extended graph formulation and vector
flow field. Experimental results show that the proposed system
facilitates quick and easy generation of artistic sketches of
various styles.},
