Electro-Hydrodynamics (EHD) spray is an important process in many engineering operations such as ink-jet printing, spray drying ...

A well known property of human vision, known as color constancy, is the ability to correct for color deviations caused by a difference in illumination. A common approach to investigate color constant behavior is by psychophysical experiments, regarding the human visual system as a black box responding to a well defined change in an laboratory setup. A fundamental problem in psychophysical exper...

This paper presents the first fully automatic color analysis system suited for business documents. Our pixelbased approach uses mainly color morphology and does not require any training, manual assistance, prior knowledge or model. We developed a robust color segmentation system adapted for invoices and forms with significant color complexity and dithered background. The system achieves several...

In the action-space account of color, an emphasis is laid on implicit knowledge when it comes to experience, and explanatory ambitions are expressed. If the knowledge claims are interpreted in a strong way, the action-space account becomes a form of conservative enactivism, which is a kind of cognitivism. Only if the knowledge claims are weakly interpreted, the action space-account can be seen ...

When a static stimulus appears successively at two distant locations, we perceive illusory motion of the stimulus across them-long-range apparent motion (AM). Previous studies have shown that when the apparent motion stimuli differ in shape, interpolation between the two shapes is perceived across the AM path. In contrast, the perceived color during AM has been shown to abruptly change from the...

We present a video analysis framework that integrates prior knowledge in object tracking to automatically detect humans and faces, and can be used to generate abstract representations of video (key-objects and object trajectories). The analysis framework is based on the fusion of external knowledge, incorporated in a person and in a face classifier, and low-level features, clustered using tempo...

Advances in restorative dentistry have made many tooth whitening techniques economical and cost effective both in developed and developing countries. The purpose of this study was to evaluate the attitude and awareness of tooth bleaching among a sample of adults attending shopping malls in Riyadh city, Saudi Arabia. A cross sectional survey was performed in four major malls located in different...

Although the aging process begins at birth, fears about late adulthood can foster anxiety in younger cohorts about this time of life. This study examines the relationship between non-elderly subjects' (n = 884, 18-55 years) knowledge of and anxieties regarding personal aging and their gender and race. We hypothesized that non-elderly women and persons of color, those who will experience multipl...

We propose an image segmentation method based on combining unsupervised clustering in the color space with region growing in the image space. No ‘a priori’ knowledge is required about the number of regions in the image. The algorithm is useful for marker extraction or complete segmentation of multidimensional, and in particular color, images. The running time depends mostly upon the speed of th...

Abstract The aim of intercultural translation is to communicate. Communication is acted via verbal as well as visual means. The interaction of verbal and visual means of communication makes a set of complex situations which demand special attention in translation. One context in which the interaction of visual and verbal elements gets vital importance is children’s picture books. Color is an in...
