AbstructThe impact of pictorial knowledge representation is demonstrated for two examples of time series analysis in seismology. The approaches perform a) automated recognition of known event signatures and b) high-resolution onset timing of later phases. Both methods work well under extreme conditions of noise and achieved human-like performance in recognizing known situations. Crucial for thi...

In this chapter, we report the concept and results of an empirical study that explored the effects of immersion and pictorial realism on the sense of presence in a virtual environment (VE). The VE used was similar to a typical industrial application. Seventy-seven participants each experienced one of four settings with varied combinations of immersion and pictorial realism, displayed in a proje...

We show that image statistics can be used to analyze and transfer simple notions of pictorial style of paintings and photographs. We characterize the frequency content of pictorial styles, such as multi-scale, spatial variations, anisotropy properties, using a multi-scale and oriented decomposition, the steerable pyramid. We show that the average of the absolute steerable coefficients as a func...

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...

Abstract Maria-Theresia Walach, Melanie Cookson-Carter and Rachel Roberts discuss the life work of Captain William Nelson Greenwood, whose legacy includes a mysterious tide calculator
