The low accuracy rates of text-shape dividers for digital ink diagrams are hindering their use in real world applications. While recognition of handwriting is well advanced and there have been many recognition approaches proposed for hand drawn sketches, there has been less attention on the division of text and drawing. The choice of features and algorithms is critical to the success of the rec...

Simple geometric shape drawing tasks are commonly used to diagnose and monitor patient performance for a range of clinical and neuropsychological conditions. Assessment relies upon observing the presence of components within a drawn image. Application of assessment criteria has been shown to vary amongst trained raters. An algorithm is presented to automatically extract the components from the ...

Most of the time developers make extensive use of software tools in a software development process to support them in their day-to-day work. One of the first and most important phases is the design phase. Here tools are missing which support the creative and collaborative workflow (parallel/distributed). At the moment software designers uses classic whiteboards in team meetings to express their...

Drawing tasks are used widely within neuropsychology for the assessment and monitoring of a variety of conditions. Automated assessment of these tasks improves their repeatability and accuracy in use alongside a reduction in trained therapist resource loading. Using images from test responses collected in an assessment of the condition of visuo-spatial neglect, this paper presents a method util...

For improving the efficiency of 2D animation production, this paper presents a method to create in-between frames based on hand-drawn key-frames. The outlines of characters or objects on two key-frames are used as inputs. First, a skeleton linkage of the target object is automatically constructed by rasterizing each of input key-frames and then applying a pixel-based skeleton extraction method....

In this paper, we describe a prototype interface that facilitates the control of a mobile robot team by a single operator, using a sketch interface on a Tablet PC. The user draws a sketch map of the scene and includes the robots in approximate starting positions. Both path and target position commands are supported as well as editing capabilities. Sensor feedback from the robots is included in ...

The ordinary Fourier coefficients are difficult to use as input to categorizers because they contain factors dependent upon size and rotation as well as an arbitrary phase angle. From these Fourier coefficients, however, other more useful features are derived. By using these derived property constants, a distinction is made between genuine shape constants and constants representing size, locati...

Presents one (or more) cartoons or humorous images.

Previous research has shown that humor and self-presentation are linked in several ways. With regard to individual differences, it turned out that gelotophilia (the joy of being laughed at) and katagelasticism (the joy of laughing at others) are substantially associated with the histrionic self-presentation style that is characterized by performing explicit As-If-behaviors (e.g., irony, parodyi...
