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 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 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 کاملFusion of Multispectral and SAR Images by Intensity Modulation
This paper presents a novel multi-sensor image fusion algorithm, which extends pan-sharpening of multispectral (MS) data through intensity modulation to the integration of MS and SAR imagery. The method relies on SAR texture, extracted by ratioing the despeckled SAR image to its lowpass approximation. SAR texture is used to modulate the generalized intensity (GI) of the MS image, which is given...
متن کاملFinding Symmetry in Intensity Images
The salience of symmetry for patterns in the human visual system has been noted by a number of observers from Mach onwards. Psychophysical studies show that symmetry is important both for shape recognition and for gure-ground segregation. Here, a computational scheme for detecting local symmetry as an aid to detecting signiicant structures in images is presented. It is based on ltering with Gau...
