MacLeod and Hodder (1998) demonstrated that presenting two different incongruent color words in the same color on a single Stroop trial resulted in no more interference than did presenting the same incongruent color word twice, and concluded that the first word captured attention, blocking out the second. They also showed that, within a trial, neither stimulus onset asynchrony between the two i...

To gain more insight into the effect of low brain serotonin (5-HT) on brain activation related to conflict, the present study examined the effect of acute tryptophan depletion (ATD) on performance and the blood oxygen level dependent (BOLD) response during a combined cognitive and emotional Stroop task. Fifteen healthy female volunteers were tested during a placebo and tryptophan depletion sess...

The Stroop phenomenon is the finding that color naming is inhibited by incongruent color words but word reading not by incongruent colors. When the stimulus onset asynchrony (SOA) is manipulated, maximal inhibition of incongruent words on color naming is obtained when the words are presented within 100 msec of the colors, whereas facilitation of preexposed congruent words is constant. These fin...

color had a special role in the human life. today psychologists use colors to do researches and recognition of people's mental characteristics. luscher's color test is further one of many well known tests. in the literature world a poet shows his way of thinking by using some special words. this research uses the luscher color test and measures the person's psychophysical state based on samih a...

To prevent pornography from spreading on the Internet effectively, we propose a novel method of adult image detection which combines bag-ofvisual-words (BoVW) based on region of interest (ROI) and color moments (CM). The goal of BoVW is to automatically mine the local patterns of adult contents, called visual words. The usual BoVW method clusters visual words from the patches in the whole image...

In this paper we present the image classification techniques performed by the IPL Group for the subfigure classification subtask of ImageCLEF 2016 Medical Task. For the visual representation of images, various state-of-the-art visual features, such as, Bag of Visual Words computed with pyramid-histogram of-visual-words descriptors and quadtree bag-of-colors were adopted. We present the results ...

2000 To my family iii ACKNOWLEDGMENTS First and foremost, I would like to express my sincere gratitude to my advisor, Dr. Sharma Chakravarthy for giving me an opportunity to work on this interesting topic and for providing me with excellent advice, great guidance and support throughout the course of this research work. His tireless patience and knowledge have been invaluable. Without his guidan...

The primary objective of the Rapid Serial Visual Presentation Panel (RSVPP) was to aid in understanding the Arabic moving messages in different public places such as mosques, hospitals, factories, emergencies, malls, and markets. RSVPP is potentially useful tool for presenting important intensive information in a rapid manner. Speed of showing words in the screens, colors of fonts/backgrounds, ...

In this article we provide an analysis of existing methods for the incorporation of color in bag-of-words based image representations. We propose a list of desired properties on which bases fusing methods can be compared. We discuss existing methods and indicate shortcomings of the two well-known fusing methods, namely early and late fusion. Several recent works have addressed these shortcoming...

In this paper we present the methods and techniques performed by the IPL Group for the concept detection task of ImageCLEF 2017. A probabilistic k-nearest neighbor approach was used for automatically detecting multiple concepts in medical images. The visual representation of images was based on the well known, bag of visual words and bag-of-colors models. Detection performance was further enhan...
