Line Drawings (line + drawing)
Selected AbstractsMetamemory and reality monitoringAPPLIED COGNITIVE PSYCHOLOGY, Issue 4 2002Amy Kelly Metamemory judgements and reality monitoring judgements were compared for real and imagined stimuli. Line drawings of everyday items were either perceived or imagined in differing ratios, to (a) investigate people's ability to predict the class of item that would be better recalled (Judgements of Learning, JOL), and the class of item which would be better sourced (Judgements of Source, JOS) in a future recall test, and (b) test the hypothesis that participants would show a bias towards calling remembered items real when the source had been forgotten. Although participants' JOLs indicated that they believed real items would be more memorable than imagined, in both experiments a larger proportion of items from either class (real or imagined) was only recalled when presentation modality was less frequent for that class. By contrast, JOSs were no different for real or imagined items, even though source attribution was more accurate for real than imagined items. An attribution of memories to real rather than to imagined events that often occurs when participants are unsure about the source (labelled a ,bias towards the real') was due to phenomenological qualities of the memories. The results are discussed in terms of Johnson and Raye's (1981) reality-monitoring model. Copyright © 2002 John Wiley & Sons, Ltd. [source] A Hidden-picture Puzzles GeneratorCOMPUTER GRAPHICS FORUM, Issue 7 2008Jong-Chul Yoon Abstract A hidden-picture puzzle contains objects hidden in a background image, in such a way that each object fits closely into a local region of the background. Our system converts image of the background and objects into line drawing, and then finds places in which to hide transformed versions of the objects using rotation-invariant shape context matching. During the hiding process, each object is subjected to a slight deformation to enhance its similarity to the background. The results were assessed by a panel of puzzle-solvers. [source] A new species and a key to Greek Praon Haliday (Hymenoptera, Braconidae, Aphidiinae)MITTEILUNGEN AUS DEM MUSEUM FUER NATURKUNDE IN BERLIN-DEUTSCHE ENTOMOLOGISCHE ZEITSCHRIFT, Issue 1 2003Dr. Nickolas G. Kavallieratos Abstract The genus Praon Haliday in Greece consists of 6 species, the newly described P. orpheusi included (Greece, Bulgaria). The new species emerged from the aphid Macrosiphum (Macrosiphum) rosae (Linnaeus) infecting Rosa sempervirens L. and Rosa caesia Sm. It is diagnosed and illustrated with photographs from the scanning electron microscope and line drawing. Furthermore, a key for the identification of species of Praon occurring in Greece is given, followed by photographs from the scanning electron microscope and line drawings. Finally, the parasitoid-aphid-plant associations of the Greek species mentioned in the key, some of which have also been found in Bulgaria and Turkey, are presented. [source] Multi-scale Feature Extraction on Point-Sampled SurfacesCOMPUTER GRAPHICS FORUM, Issue 3 2003Mark Pauly We present a new technique for extracting line-type features on point-sampled geometry. Given an unstructuredpoint cloud as input, our method first applies principal component analysis on local neighborhoods toclassify points according to the likelihood that they belong to a feature. Using hysteresis thresholding, we thencompute a minimum spanning graph as an initial approximation of the feature lines. To smooth out the featureswhile maintaining a close connection to the underlying surface, we use an adaptation of active contour models.Central to our method is a multi-scale classification operator that allows feature analysis at multiplescales, using the size of the local neighborhoods as a discrete scale parameter. This significantly improves thereliability of the detection phase and makes our method more robust in the presence of noise. To illustrate theusefulness of our method, we have implemented a non-photorealistic point renderer to visualize point-sampledsurfaces as line drawings of their extracted feature curves. [source] 636.

[source] The representation of Kanizsa illusory contours in the monkey inferior temporal cortexEUROPEAN JOURNAL OF NEUROSCIENCE, Issue 10 2008Gy. Sáry Abstract Stimulus reduction is an effective way to study visual performance. Cues such as surface characteristics, colour and inner lines can be removed from stimuli, revealing how the change affects recognition and neural processing. An extreme reduction is the removal of the very stimulus, defining it with illusory lines. Perceived boundaries without physical differences between shape and background are called illusory (or subjective) contours. Illusory and real contours activate early stages of the macaque visual pathway in similar ways. However, data relating to the processing of illusory contours in higher visual areas are scarce. We recently reported how illusory contours based on abutting-line gratings affect neurones in the monkey inferotemporal cortex, an area essential for object and shape vision. We now present data on how inferotemporal cortical neurones of monkeys react to another type of shapes, the Kanizsa figures. A set of line drawings, silhouettes, their illusory contour-based counterparts, and control shapes have been presented to awake, fixating rhesus monkeys while single-cell activity was recorded in the anterior part of the inferotemporal cortex. Most of the recorded neurones were responsive and selective to shapes presented as illusory contours. Shape selectivity was proved to be different for line drawings and illusory contours, and also for silhouettes and illusory contours. Neuronal response latencies for Kanizsa figures were significantly longer than those for line drawings and silhouettes. These results reveal differences in processing for Kanizsa figures and shapes having real contours in the monkey inferotemporal cortex. [source] Hospital Birthing Room Design: A Study Of Mothers' Perception Of HominessJOURNAL OF INTERIOR DESIGN, Issue 1 2004Jung-Hye Shin M.S. ABSTRACT The objective of this research is to examine a select set of interior design elements for their contribution to the perception of hominess in a birthing environment. Seven interior design elements were studied. Seven line drawings were generated to illustrate variability in the manipulation level of each design element, resulting in a total of 49 line drawings. Subjects were asked to rate each of the 49 drawings with three different outcome measures: the degree of hominess perceived, the likeliness of using the setting as their birthing place (preference), and the perception of personal control. Researchers employed multiple comparisons with analysis of variance to investigate the contribution of each interior design element to each of the three outcomes. Relationships among the three outcomes were then investigated through coefficient correlation analysis. Finally, a General Linear Model was utilized to further investigate degree of impact of each design element. The findings indicate that perceived hominess in the birthing place is important to women. Furthermore, there is agreement about the use and manipulation of interior design in enhancing the perception of hominess. Successful design in hospital birthing settings can contribute to women's feeling of hominess by providing personal control over visual access, patient exposure, family visitation, and the immediate environment.

[source] Memory for drawings in locations: Spatial source memory and event-related potentialsPSYCHOPHYSIOLOGY, Issue 4 2000Cyma van Petten Event-related potentials (ERPs) were recorded during recognition tasks for line drawings (items) or for both drawings and their spatial locations (sources). Recognized drawings elicited more positive ERPs than new drawings. Independent of accuracy in the spatial judgment, the old/new effect in the source recognition task was larger over the prefrontal scalp, and of longer temporal duration than in the item recognition task, suggesting that the source memory task engaged a qualitatively distinct memory process. More posterior scalp sites were sensitive to the accuracy of the source judgment, but this effect was delayed relative to the difference between studied and unstudied drawings, suggesting that source memory processes are completed after item recognition. Similarities and differences between spatial source memory and memory for conjunctions of other stimulus attributes are discussed, together with the role of prefrontal cortex in memory.
