While it is difficult to imagine the way someone with mental illness perceives the world, paintings produced by mental illness sufferers with artistic talents offer a hint of this experience. Here we analyze these images in terms of statistics related to low-level visual processing. It is known that art in general possesses regular spatial frequency amplitude spectra, probably due to factors in...

Image patches of different spatial frequencies are likely to have different perceptual significance as well as reflect different physical properties. Incorporating such concept is helpful to the development of more effective image retrieval techniques. We introduce a method which separates an image into layers, each of which retains only pixels in areas with similar spatial frequency characteri...

This study obtained information about the frequency, content, and functions of inner speech by asking 380 participants what they typically say to themselves using an open-format thought-listing procedure. Participants mostly reported talking to themselves about themselves—i.e., evaluating the self, emotions, physical appearance, and relationships. Self-reported inner speech was also about indiv...

This article describes a comprehensive system for surveillance and monitoring applications. The development of an efficient real time video motion detection system is motivated by their potential for deployment in the areas where security is the main concern. The paper presents a platform for real time video motion detection and subsequent generation of an alarm condition as set by the paramete...

Modern algorithms that process images to be viewed by humans analyze the images strictly as signals, where processing is typically limited to the pixel and frequency domains. The continuum of visual processing by the human visual system (HVS) from signal analysis to cognition indicates that the signal-processing based model of the HVS could be extended to include some higher-level, structural p...

With the proliferation of recommendation functions (RF) on e-Commerce websites, there is growing confusion about how various RF types affect consumers’ beliefs and behavior. Despite the importance of understanding the differential effects of RF types, research focusing on the comparison between provider-generated recommendations (PGRs) and user-generated recommendations (UGRs) has received litt...

We address the question of whether or not the properties of all low-luminosity flat spectrum radio sources, not just the obvious BL Lac objects, are consistent with them being the relativistically beamed counterparts of the low radio luminosity radio galaxies (the Fanaroff-Riley type 1 FR I). We have accumulated data on a well-defined sample of low redshift, core-dominated, radio sources all of...

Objectives To determine the percentage of persistant apical lesions positive for bacterial nucleic acids, to detect microorganisms difficult to cultivate in persistant apical lesions by PCR and relate them to endodontic failure, clinical symptoms and diabetes mellitus. Materials and methods The samples of persistent apical lesions were collected during apicoectomy. Bacterial ubiquitous primer...

The static yield stress and complex dielectric constant of glass spheres dispersed in vacuum oil are measured as a function of ~applied electric field! frequency and water content. Based on a model in which the dielectric constants of the solid and the liquid constituents are given by the Debye form with a log-normal distribution of relaxation times, it is shown that the electrical and the mech...

It is safe to posit that human beings have been interested in their own inner mental experiences from the moment they became aware of them, arguably over 60,000 years ago (Leary, 2004). In sharp contrast, growth in the actual scientific examination of these inner experiences is remarkably recent (e.g., Csikszentmihalyi and Figurski, 1982; Klinger and Cox, 1987–1988; Goldstein and Kenen, 1988; H...
