Theory of tactile pictures argues that untrained blind subjects can recognize raised, outline pictures. It contends the blind person's knowledge of the shapes of common objects is like that of the sighted, and the blind person's pictorial abilities use the same principles as the sighted person's. To test this theory, blind children (aged 8-13) and blindfolded age-matched sighted children were a...

Pictorial and tangible paired-stimulus preference assessments were compared with 4 adolescents with developmental disabilities. In the tangible assessment, two stimuli were placed in front of the participant on each trial; in the pictorial assessment, two line drawings were placed in front of the participant on each trial. Approach responses were recorded for each assessment. The assessments ge...

Accurate segmentation of circular arcs from line drawings is essential for higher level processing in document analysis and recognition systems. In spite of the prevalence of arc segmentation methods, robust algorithms that perform well in complex graphic environments are scarce, and methods to evaluate such algorithms are even more rare. Extending our previous work, we propose a comprehensive ...

The goal of this paper is to announce the NicIcon collection of handwritten sketches containing iconic gestures. These data have recently been collected in our group with the goal to develop and assess pen input recognition technologies for the domain of crisis management. In our envisaged scenarios, users can use the pen to enter, e.g., information about the location of certain objects or the ...

Pop Art is the representative of a cultural identity that has been represented as a kind of art in the mid-twentieth century. It is based on the ordinary manifes‌tations of people’s lives, and by concentrating on media and propaganda it has become pervasive in a short time as if it is a newly emerged culture that has appeared not from the inside of community but from outside and by those sociol...

Processing colored pictures of objects results in a preference to choose the former color for a specific object in a subsequent color choice test (Wippich & Mecklenbräuker, 1998). We tested whether this implicit memory effect is independent of performances in episodic color recollection (recognition). In the study phase of Experiment 1, the color of line drawings was either named or its appropr...

Locating sensors in 2D can be modelled as an Art Gallery problem. Tasks such as surveillance require observing or “covering” the interior of a polygon with a minimum number of sensors (IC, Interior Covering). Edge Covering (EC) is sufficient for tasks such as inspection or image based rendering. As IC, also EC is NP-hard, and no finite algorithm is known for its exact solution. A number of heur...
