We introduce a new method for finding nodes semantically related to a given node in a hyperlinked graph: the Green method, based on a classical Markov chain tool. It is generic, adjustment-free and easy to implement. We test it in the case of the hyperlink structure of the English version ofWikipedia, the on-line encyclopedia. We present an extensive comparative study of the performance of our ...

Scientific illustration can be defined as a realistic representation of an object that the illustrator or scientist observes, pointing out features they want to show. Over years, has fulfilled different objectives, becoming indispensable tool in science service, being extremely important understanding natural world and recognized significant factor emergence modern (MOSER, 2014). The scientific...

Colorization is a computerized process of adding color to a black and white print, movie and TV program. The authors have proposed automatic colorization algorithms by giving a partial color to a monochrome image. This paper focuses on the colorization process which can produce a color image from a monochrome image with a small number of color pixels, and proposes a novel color image coding alg...

Medical Illustrations in Medieval Manuscripts, by LOREN MACKINNEY, London, Wellcome Historical Medical Library, 1965, pp. xvii, 263, 104 plates, 105s. It is a pity that Loren MacKinney did not live to see the publication of this beautifully produced book, which represents to some extent the culminating point of his thirty years' search for medical illustrations in medieval manuscripts. He had i...

Applying selective emphasis to photographs is a critical aspect of the visual design process. There is evidence from psychophysics that contrast in texture is a key contributor to saliency in an image, yet unlike other low-level perceptual features, texture cannot be directly modified with existing image-processing software. We present a post-processing technique to subtly change the salience o...

SenseCam is a wearable digital camera that automatically takes pictures due to timers or sensorbased triggers. We propose using a compass sensor to trigger picture-taking, and detail our implementation of this idea as an add-on module for the SenseCam. We also describe a method for comparing triggering algorithms for SenseCam using a video recorder and video annotation software. We use this met...

The visual information provided by 2D images is typically static and so the entire content of an image is shown at once. When image components are now annotated to communicate the image’s content more clearly, the actual information of the image is partially hidden. However, by hiding an image’s annotations by default, the image can be turned into an interactive medium for which a user can dema...
