We present a new recognition system for detecting general articulated skeletal figures in sketch-based applications. We abstract drawing style from recognition by defining figures using two data models: templates and figure targets. Our system recognizes general skeletal figures consisting of lines and ellipses which may be drawn partially off the canvas with the system automatically completing...
We study methods for drawing trees with perfect angular resolution, i.e., with angles at each node v equal to 2π/d(v). We show: 1. Any unordered tree has a crossing-free straight-line drawing with perfect angular resolution and polynomial area. 2. There are ordered trees that require exponential area for any crossing-free straight-line drawing having perfect angular resolution. 3. Any ordered t...
Some young children are able to create stunningly realistic drawings resembling those of adult artists. What perceptual abilities underlie this talent? This study examined two candidate skills on which adult artists excel: the ability to segment a complex form mentally (measured by the Block Design Task) and the ability to see hidden forms (measured by the Group Embedded Figures Test). Sixty-se...
People perceive patterns in representations, patterns that may not have been initially intended. This phenomenon of emergence is deemed to play an important role in design. Computer based design assistants can and should support this human perceptual ability, using pattern recognition to anticipate human designers’ perception of emergent shapes and supporting the subsequent manipulation of and ...
Mathematical and scientific writing call for figures that accurately and attractively integrate typography and numerical data. Widely-used commercial and non-commercial drawing programs exist, as do dozens of lesser-known utilities. This article describes an addition to the list: ePiX, a collection of command line utilities for creating mathematically accurate, logically structured, camera-qual...
HISTORICAL BACKGROUND Although examples of informal drawing of networks and hand-drawn graph layouts can be found stretching back many decades, the discipline of visualizing network data in a systematic fashion dates back only to the availability of computers, with an early paper by Tutte in 1963 titled “How to Draw a Graph” being a prime example. In 1992, the conference International Symposium...
This work explains the development of a novel approach to beautify a face, merging an evolutionary approach and aesthetics graph drawing. The objective of this work is to build a beautify face seen against the input face. The aesthetics graph drawing algorithm works as the mutation operator. The approach of force-directed graph drawing which in turn is the solution to aesthetical graph drawing ...
In spite of great advances in the automatic drawing of medium and large graphs, the tools available for drawing small graphs exquisitely (that is, with the aesthetics commonly found in professional publications and presentations) are still very primitive. Commercial tools, e.g., Claris Draw, provide minimal support for aesthetic graph layout. At the other extreme, research prototypes based on c...
