Three-dimensional discrete cosine transform (3-D DCT) coding has the advantage of reducing the interframe redundancy among a number of consecutive frames, while the motion compensation technique can only reduce the redundancy of at most two frames. However, the performance of the 3-D DCT coding will be degraded for complex scenes ...

Bright and dark flashes are typical artifacts in degraded motion picture material. The distortion is referred to as "dirt and sparkle" in the motion picture industry. This is caused either by dirt becoming attached to the frames of the film, or by the film material being abraded. The visual result ...
Mitsunaga M - - 1994
Real-time recording of a moving object was made with persistent spectral hole burning of a cryogenic Eu(3+):Y(2)SiO(5) crystal. In a basic holographic configuration the ultrastable laser frequency was continuously scanned within the (7)F(0)-(5)D(0) absorption line (typically 200 MHz in 20 s) while the object was in motion, thus permitting the ...

When pictures of simple shapes (square, diamond) were seen frontally and obliquely, (1) the shapes with a deeper extent into pictured space underwent more rotation (Goldstein, 1979), which is an apparent turning to keep an orientation toward an observer's changing position; (2) there was little effect of whether the observer ...
Beer J M - - 1993
This study tested scene perception during depicted self-movement. In Experiment 1, viewers reproduced angular scene configurations, revealed over time by camera motions in depth. Viewers used visible flow to update off-screen locations of landmarks that had been drawn from view and thereby perceived scenes in depth beyond the display's boundaries. ...
Ai Z - - 1993
An algorithm for accurate rendering of space-filling molecular models with shadows is presented. The intensity of light and cast shadows are computed to generate realistic pictures. Arbitrary numbers of light sources, which may be at infinite or finite distances can be applied. Hidden-surface removal, lighting, and shadowing are presented in ...
Oppenheimer D - - 1993
The 25 April 1992 magnitude 7.1 Cape Mendocino thrust earthquake demonstrated that the North America-Gorda plate boundary is seismogenic and illustrated hazards that could result from much larger earthquakes forecast for the Cascadia region. The shock occurred just north of the Mendocino Triple Junction and caused strong ground motion and ...
Hammerl M - - 1993
In an experiment designed to demonstrate evaluative conditioning, subjects were shown 48 pictures of sculptures that they rated on a scale with 21 categories (-10 to +10). Then, the two most liked pictures (L) were paired with pictures from the categories -1, 0, or +1 (N). In contrast to prior ...
Ohman A - - 1993
Normal subjects (n = 64) were exposed either to pictures of snakes and spiders or to pictures of flowers and mushrooms in a differential conditioning paradigm in which one of the pictures signaled an electric shock. In a subsequent extinction series, these stimuli were presented backwardly masked by another stimulus ...

Argyrosis is a cutaneous discoloration caused by silver. Ocular involvement, including conjunctival and corneal discoloration, has been previously reported. To our knowledge, a retinal involvement was never reported and no data is available about fluorescein angiography patterns of patients with argyrosis. Fluorescein angiography was performed in six consecutive patients with ...
Yu K - - 1992
Five experiments examined whether recognizable stimuli predominate in binocular rivalry. It was found that a face predominated more than did a pattern equated for spatial frequency, luminance, and contrast; an objective reaction time procedure confirmed predominance of the face. The face was still liable to fragmentation as stimulus size increased. ...
Mead A M - - 1992
When some pictures are mirror reversed, aesthetic evaluations of them change dramatically. Stimulus features that may be important in contributing to this effect are: (a) location of areas of principal interest or weight in the picture space, (b) cues that suggest a direction of motion within the picture. Dextrals and ...
Denisyuk Y N - - 1992
Concepts underlying a holographic method of recording light-wave-train motion pictures were first reported by Yu. N. Denisyuk and co-authors in 1969. Analyses from that period are presented here that relate the degree of temporal and spatial coherence of the laser source to the recorded and reconstructed holographic distributions.
Wilesmith J W - - 1992
A standard questionnaire was used to record the presence of specific clinical signs reported for histopathologically confirmed cases of bovine spongiform encephalopathy observed before June 30, 1990, and the frequencies of these signs were analysed. The signs most frequently recorded were apprehension, hyperaesthesia and ataxia, and there were variations in ...

It is demonstrated that observers may relate to two parts of the same object by using two different frames of reference. Subjects were asked to indicate directions within a model of a hallway in which signs were posted on a single prism. The majority of subjects interpreted a sign frontally ...
Johnston A - - 1992
When information about three-dimensional shape obtained from shading and shadows is ambiguous, the visual system favours an interpretation of surface geometry which is consistent with illumination from above. If pictures of top-lit faces are rotated the resulting stimulus is both figurally inverted and illuminated from below. In this study the ...

Pleural fluid analysis is often the initial diagnostic test used to determine the cause of a pleural effusion. We prospectively studied 33 consecutive patients with pleural effusions to determine whether the fluid arose from a transudative or an exudative process. Clinical judgment by an internist before thoracentesis and both serum ...

The European Community must become a fully integrated market by 1992. The differing national requirements for pharmaceutical product registration constituted a barrier, unresolved by the creation of a nonmandatory process of mutual recognition of pharmaceutical licences. Interested parties have been asked to recommend measures to abolish the remaining barriers. The ...

Previous research has shown that when right-handed subjects prefer one orientation of a picture over its mirror image, the more interesting or important content is on the right. Location of content, however, is only one of a number of possible asymmetric aspects of picture composition. To determine whether the relationship ...

32 undergraduates viewed 10 photographs of faces for 3 sec. each in a brightly or dimly illuminated room. Then they viewed 40 photographs in the same light, including the original 10, and identified each photograph as new or old. Subjects recognized significantly more photographs in the bright illumination condition, possibly ...

The amount that a pictured lattice appears to be swung from its frame changes with subjects' viewpoint, in contrast with previous experiments using insufficient range of rotation. Also, this effect is shown to be independent of the physical slant of the picture surface, though not necessarily of border-shape information. Analysis ...

Observers inspected for different lengths of time pictures which contained high-resolution information within an eye-contingent viewing window and low-resolution information outside the area of that window. A recognition test followed in which the pictures inspected were presented together with other, distractor, pictures. The time required to reach 75% picture recognition ...
Goldstein E B - - 1988
Cutting (1988) suggests that changes in the perceived orientations of pictured objects that occur with changes in viewing angle are caused by the geometrical changes that accompany these changes in viewing angle. His geometrical analysis does predict the differential rotation effect reported by Goldstein (1979, 1987), but fails to predict ...
Ferré J C - - 1988
The authors question whether strengthening beams and spans for the calvarium really exist and, if so, what are their exact anatomic counterparts and their exact function in the resistance of the calvarium. They opine that this function is of secondary importance except for the frontal and internal occipital pillars. The ...
Goldstein E B - - 1987
Judgments of the spatial layout of a three-dimensional array of pictured dowels remain relatively constant as viewing angle changes, whereas judgments of their orientation relative to the observer (perceived orientation) vary. These changes in perceived orientation as viewing angle changes, called the differential rotation effect (DRE), also occur for stimuli ...

The Session Evaluation Questionnaire measures two dimensions of participants' perceptions of psychotherapy sessions, depth and smoothness, and two dimensions of post-session mood, positivity and arousal. In ratings by therapists and in ratings by clients, the same dimensions were identified as underlying variation across sessions and variation across clients. Thus these ...
Bergström S S - - 1984
A homogeneous grey picture and a 'Mondrian' type of picture were illuminated by a projector with square-wave gratings of thirty different contrast values used as slides. Ten observers reported whether the picture appeared three-dimensional (3-D) (pleated) or flat. 3-D responses in this situation indicate colour constancy 'at the cost of' ...

Two experiments are reported which demonstrate the effects of light-source position as an intervening variable upon the perception of relief in pictures. In the first experiment, it is shown that the pattern of light (attached shadow) falling upon forms that can be recognized as having unambiguous surface relief (concave and ...
Abramson P R - - 1983
The expression of sexuality in best-selling novels and major motion pictures was examined. There are two reasons that such stimuli merit systematic analysis. First and foremost is the finding that best-selling novels and major motion pictures exist as a primary source of sexual information. Of equal importance, however, is the ...
Elliott R - - 1983
This article illustrates a new approach to the study of change processes in psychotherapy. The approach involves selecting significant change events and analyzing them according to the Comprehensive Process Model. In this model, client and therapist behaviors are analyzed for content, interpersonal action, style and response quality by using information ...
Abramson N H - - 1983
Holographic recordings have been made using lasers of short coherence and pulse length. Continuous frameless moving pictures show the wave front (pulse front) of light reflected by a mirror and focused by a lens. Light passing through interferometers has also been studied using this new method of dynamic observation. Cross ...
Berbaum K - - 1983
The perception of depth in monocularly viewed pictures has been investigated with the use of a binocular rangefinder developed by Gregory. Two experiments are reported which focus upon stimulus conditions that were identified by Haber as conventions for rendering depth in pictures. Several conclusions, which concern assumptions that must be ...
Alexander M J - - 1982
The purposes of this study were (1) to determine the relative motions of the upper limb segments during the execution of the softball windmill pitch (2) to attempt to determine the effect of these motions on the performance of the skill. High speed motion picture film was used to calculate ...
