Intensity modulation of pseudocolor images.
Fura-2 is a popular real-time fluorescent indicator used to image intracellular, free calcium concentrations ([Ca2+]i) in living cells. One difficulty with fura-2-based digital imaging is how to best display the [Ca2+]i information that is acquired. Typically, only the [Ca2+]i as pseudocolor data are displayed, and the localization and intensity of the dye are not presented. This paper describe...
متن کاملPseudocolor Processing of Graphical Images Using Multicolor Perceptions
In digital image processing, image enhancement is employed to give a better look to an image. Color is one of the best ways to visually enhance an image .Pseudo-color image processing assigns color to grayscale images. This is useful because the human eye can distinguish between millions of colures but relatively few shades of gray. Pseudo-coloring has many applications on images from devices c...
متن کاملGradient-based value mapping for pseudocolor images
bstract. We develop a method for automatic colorization of imges (or two-dimensional fields) in order to visualize pixel values nd their local differences. In many applications, local differences in ixel values are as important as their values. For example, in topogaphy, both elevation and slope often must be considered. Gradientased value mapping (GBVM) is a technique for colorizing pixels ase...
متن کاملAnalysis of Pancreas Histological Images for Glucose Intolerance Identification using ImageJ – preliminary results
The observation in microscopy of histological sections allows us to evaluate structural differences, in pancreatic cells, between rats with normal glucose tolerance and with glucose intolerance (pre-diabetic) situation. Nevertheless, this pre-diabetic condition implies subtle changes in islets of Langerhans structure. This and the normal variability among sampled cells makes difficult the task ...
متن کاملDigital Darkfield Analysis of Lattice Fringe Images with ImageJ
Digital-darkfield analysis involves the spatial mapping of selected frequencies across a digitized image, much as analog (e.g. electron-optical) darkfield-imaging allows one to locate crystals responsible for a given diffraction spot. This analysis involves a type of image decomposition which, like wavelets, is intermediate between direct and reciprocal (spatial-frequency) space [1]. Digital-da...
