Pigeons are well known for their visual capabilities as well as their ability to categorize visual stimuli at both the basic and superordinate level. We adopt a reverse engineering approach to study categorization learning: Instead of training pigeons on predefined categories, we simply present stimuli and analyze neural output in search of categorical clustering on a solely neural level. We pr...

Pleural ultrasonography (US) represents nowadays a useful diagnostic tool in the management of pleural diseases. Detection and evaluation of pleural effusions, pneumothorax and pleural-based lesions can be performed with US, which has the advantages of wide availability, low cost, absence of radiation exposure, and portability. It is the best method for guiding interventional procedures in the ...

This paper describes an eecient approach to pose invariant pictorial object recognition employing spectral signatures of image patches that correspond to object surfaces which are roughly planar. Based on Singular Value Decomposition (SVD), the aane transform is decomposed into slant, tilt, swing, scale and 2D translation. Unlike previous log-polar representations which were not invariant to sl...

Scene understanding remains a significant challenge in the computer vision community. The visual psychophysics literature has demonstrated the importance of interdependence among parts of the scene. Yet, the majority of methods in computer vision remain local. Pictorial structures have arisen as a fundamental parts-based model for some vision problems, such as articulated object detection. Howe...

The aims of this study were 1) to determine the relation between facial pictorial RPE and facial EMG 2) to compare the correlation with facial muscle activity and active muscle activity between Borg and facial pictorial RPE scale. A cross-sectional, perceptual estimation design was used to assess exertional perceptions during a load-incremented cycle ergometer. Forty volunteers, including 22 ma...

Usually it is accepted that human manifestations such as music or painting share a common artistic trait. However, very little is known about the genetic, behavioral, developmental and neurobiological basis of such a musical-pictorial "universal". In an attempt to approach commonalities and differences between the psychology of music and pictorial art in Experiment 1 we investigated the emotion...

We consider the task of visual net surgery, in which a CNN can be reconfigured without extra data to recognize novel concepts that may be omitted from the training set. While most prior work make use of linguistic cues for such ”zero-shot” learning, we do so by using a pictorial language representation of the training set, implicitly learned by a CNN, to generalize to new classes. To this end, ...

As management researchers seek ever more lucid means of analysing organisations, image is at last beginning to challenge the supremacy of the written word. Yet, despite fifteen-thousand years of art history, the use of image as a scientific instrument is still in its embryonic stages. This paper explores the origins and use of pictorial representation as an innovative research technique for the...

In order to assess the influence of illumination direction on shape constancy, we studied the pictorial relief of computer images of globular 3-D objects. We used two globally convex objects, one with a furrow and one with a dimple. Observers adjusted local surface attitude probes at 200-250 different locations in the image such that they seemed to lie on the pictorial surface. We manipulated t...

this study compared the effects of two annotation modalities on the reading comprehension of iranian intermediate level efl learners. the two experimental groups under study received treatment on 10 academic l2 reading passages under one of two conditions: one group received treatment on key words in the reading passages through a multimedia environment providing textual annotations. the second...
