Restoration of degraded moving image for predicting a moving object

ELECTRONICS & COMMUNICATIONS IN JAPAN, Issue 2 2009
Kei Akiyama
Abstract Iterative optimal calculation methods have been proposed for degraded static image restoration based on the multiresolution wavelet decomposition. However, it is quite difficult to apply these methods to process moving images due to the high computational cost. In this paper, we propose an effective restoration method for degraded moving images by modeling the motion of moving object and predicting the future object position. We verified our method by computer simulations and experiments to show that our method can achieve favorable results. © 2009 Wiley Periodicals, Inc.

Successful Application of Video-Projected Human Images for Signalling to Dogs

ETHOLOGY, Issue 10 2003
Péter Pongrácz
Dogs were tested (1) in a two-way choice experiment, where the experimenter indicated a baited bowl by pointing; and (2) in a task where the owner was asked to command the dog to execute simple obedience tasks. In expt 1 dogs (n = 10) were tested at first in the presence of the experimenter (three dimensional condition, 3D), that was followed by a series of pointing trials when the life-sized image of the experimenter was projected onto the wall by the means of a video-projector (two dimensional condition, 2D). Dogs performed correctly more often than expected by chance in both 3D and 2D conditions. In expt 2 the commanding owner was either present in the room (3D), or her/his image was projected on the screen (2D), or only her/his voice was audible for the dog through a speaker (0D). The performance of the dogs (n = 10) decreased to great extent comparing the 3D and 0D condition, as the number of different actions the dogs obeyed was significantly less in the 0D condition. However, there was no difference in the number of different actions obeyed in the 3D and 2D conditions. Our results show that dogs readily obey life-sized, interactive moving image in various communicative situtations. We suppose that the difference between 2D and 3D conditions can be attributed partially to the lack of some additional communicative signals as sounds (verbal cues) and odours (from the human), and to some changes in the context.

Watching moving images specifically promotes development of medial area of secondary visual cortex in rat

DEVELOPMENTAL NEUROBIOLOGY, Issue 9 2009
Baonan Sun
Abstract It is generally accepted that the cortex can be divided into numerous regions depending on the type of information each processes, and that specific input is effective in improving the development of related regions. In visual cortex, many subareas are distinguished on the basis of their adequate information. However, whether the development of a subarea can be specifically improved by its particular input is still largely unknown. Here, we show the specific effects of motion information on the development of the medial area of secondary visual cortex (V2M), a subarea associated with processing the movement component of visual information. Although watching a moving or a still image had similar effects in primary visual cortex, the moving image induced multistage development of V2M in dark-reared rats: both mRNA and protein levels of GluR2 were upregulated, the density and protein content of GluR2-positive synapses increased, and the spine density and the frequency of spontaneous excitatory postsynaptic currents (EPSCs) of pyramidal neurons in Layer 5 were elevated. Our results suggest that rats are able to identify motion information, distribute it to V2M, and then use this input to specifically improve the development of V2M. © 2009 Wiley Periodicals, Inc.

Restoration of degraded moving image for predicting a moving object

A Stitch in Time: Skills for the New Literacy

ENGLISH IN EDUCATION, Issue 1 2000
Cary Bazalgette
Abstract This article examines the relationship between moving image study and English, with particular reference to understandings of the practice of editing. Starting from the premise that English teachers support the study of moving images in their subject, the article interrogates the kind of knowledge and understanding, and the range of skills which are implicated by editing. It ends by calling for a recasting of English in tune with the changes - and convergences - that new digital technologies are already heralding. [source]

A user-centered functional metadata evaluation of moving image collections

JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 8 2008
Ying Zhang
In this article, the authors report a series of evaluations of two metadata schemes developed for Moving Image Collections (MIC), an integrated online catalog of moving images. Through two online surveys and one experiment spanning various stages of metadata implementation, the MIC evaluation team explored a user-centered approach in which the four generic user tasks suggested by IFLA FRBR (International Association of Library Associations Functional Requirement for Bibliographic Records) were embedded in data collection and analyses. Diverse groups of users rated usefulness of individual metadata fields for finding, identifying, selecting, and obtaining moving images. The results demonstrate a consistency across these evaluations with respect to (a) identification of a set of useful metadata fields highly rated by target users for each of the FRBR generic tasks, and (b) indication of a significant interaction between MIC metadata fields and the FRBR generic tasks. The findings provide timely feedback for the MIC implementation specifically, and valuable suggestions to other similar metadata application settings in general. They also suggest the feasibility of using the four IFLA FRBR generic tasks as a framework for user-centered functional metadata evaluations. [source]

Movement disorders associated with encephalitis lethargica: A video compilation

MOVEMENT DISORDERS, Issue 1 2006
Joel A. Vilensky PhD
Abstract Encephalitis lethargica (EL; epidemic encephalitis; von Economo's disease) often presented with a movement disorder, and the motor consequences of postencephalitic parkinsonism (PEP) were characteristic of the chronic sequelae of this condition. PEP was similar to Parkinson's disease but was more variable and had some distinct features such as oculogyric crises. Although two previous publications have included video images of the movement disorders associated with EL and PEP, the sequences presented were typically short, showed only a few patients, and did not include the work of several neurologists who had the foresight to preserve filmed images of their patients. We describe the most complete record of EL and PEP moving images that have been preserved and make them available in edited form. © 2005 Movement Disorder Society [source]

Selection of lineup foils in operational contexts

APPLIED COGNITIVE PSYCHOLOGY, Issue 2 2008
Stephen Darling
It has been argued (Luus & Wells, 1991) that matching lineup foils to the description of the culprit, rather than the appearance of the suspect, brings benefits to witness performance on identification tasks, in particular by increasing the rate of correct identifications of the culprit. Recently, live identification procedures in the United Kingdom have been replaced by use of video. The reported research investigated whether use of description matching would improve lineup performance when implemented using this new video based system in an ecologically valid experiment. The effect of using moving rather than still video clips was also investigated. Participants witnessed a live staged incident, and attempted to identify the culprit later from police video lineups. Neither use of a description-matching strategy to select foils nor use of moving images produced a reliable improvement in performance for culprit present (CP) or culprit absent (CA) lineups.

Paintings, Films and Fast Cars: A Case Study of Hubert von Herkomer

ART HISTORY, Issue 2 2002
Lynda Nead
In a recent conversation with Bruno Latour, the French philosopher Michel Serres visualized his concept of modernity through the image of the automobile. The car, Serres argued, could not be defined as uniquely of one period or as belonging exclusively to the modern, being ,a disparate aggregate of scientific and technical solutions dating from different periods , The ensemble is only contemporary by assemblage.' This metaphor offers a highly productive way of looking at the history and forms of visual culture in Britain in the early twentieth century, when the technological and commercial possibilities of nineteenth-century optical developments were filtering into all aspects of cultural production and consumption. The article examines this moment via a case study of the artist Hubert von Herkomer; offering a reassessment through an examination of his paintings, films and fast cars and thereby proposing a reframing of the history of British visual culture through the integration of still and moving images.
