ii To Gustavo, for his love, patience and support, and for always making me move forward. To my parents, for their unconditional love and encouragement. To all my family and friends, who in one way or another participated in this journey. iii ACKNOWLEDGMENTS I would like to express my deepest gratitude to my mentor, Dr. Cathia Bergeron, an example as a person and a professional, who I had an im...

In this study, usability issues at the multicultural children’s book project web site of the National Library for Children and Young Adults (NLCY) in Korea were identified, particularly for children users. Suggestions for improvements include brighter colors, bigger fonts and graphics, more lively animation and sound, easier navigation, consistent interface, summary availability, better organiz...

Neuroimaging tests of sensorimotor theories of semantic memory hinge on the extent to which similar activation patterns are observed during perception and retrieval of objects or object properties. The present study was motivated by the hypothesis that some of the seeming discrepancies across studies reflect flexibility in the systems responsible for conceptual and perceptual processing of colo...

A B S T R A C T Introduction: In an oddball experiment, the context in which novel stimuli are presented affects characteristics of novelty P3, i.e. as long as there is a difficult task in which the difference between standard and target stimuli is small, recurrent presentation of a highly discrepant stimulus can lead to P300 highly similar to novelty P3. Effect of stimulus properties on P300 h...

The human facial recognition is the base for all facial processing systems. In this work a basicmethod is presented for the reduction of detection time in fixed image with different color levels.The proposed method is the simplest approach in face spatial localization, since it doesn’trequire the dynamics of images and information of the color of skin in image background. Inaddition, to do face...

A statistical learning/inference framework for color demosaicing is presented. We start with simplistic assumptions about color constancy, and recast color demosaicing as a blind linear inverse problem: color parameterizes the unknown kernel, while brightness takes on the role of a latent variable. An expectationmaximization algorithm naturally suggests itself for the estimation of them both. T...

To restore a tooth to its functional health, four basic determinants of dental esthetics; position, contour, texture and colour in the said sequence are required. Clark1 said, “Color, like form, has three dimensions, Hue, Value, and Chroma. An understanding of the science of color and color perception is crucial to success in the ever-expanding field of esthetic restorative dentistry. It is pos...

acquired color deficiency in the tritan axis in parkinson’s disease has already been reported, manifesting itself as impaired performance in various visual tasks. however, its clinical significance has always been controversial. in this study we evaluated the performance of parkinson s disease patients in lanthony 15-desaturated clinical test and for the first time, compared it with the standar...
