Line drawing techniques are important methods to illustrate shapes. Existing feature line
methods, eg, suggestive contours, apparent ridges, or photic extremum lines, solely …

We present an approach for interactively generating pen-and-ink hatching renderings based
on hand-drawn examples. We aim to overcome the regular and synthetic appearance of the …

This paper deals with the application of feature lines on patient-specific anatomical surfaces
used for treatment planning. We introduce the most commonly used feature line methods …

We propose a real-time rendering system for automatically creating a caricature drawing, ie,
an exaggerated portrait, of a human face, based on simultaneous use of a range image (or …

In recent years, an increasing number of example-based Geometric Texture Synthesis (GTS)
algorithms have been proposed. However, there have been few attempts to evaluate these …

Non-photorealistic rendering (NPR) has been used to produce stylized images, eg, in a
stippled or painted style. To evaluate NPR algorithms, similarity measurements used in …

This paper presents Celtic Canvas--a framework towards computationally generating
patterns similar to simple Celtic artwork. As Celtic patterns are highly structured, a robust …

High quality segmentations must be captured consistently for applications such as
biomedical image analysis. While human drawn segmentations are often collected because …

This paper investigates how visual cues affect human performance at a line drawing task.
Line drawing is a primitive and fundamental task using tools such as pens,(soldering) irons …

This paper presents the results of a study in which type of line drawings intended to convey
3D faces by using the normal estimation method based on the face domain knowledge …
