چکیده

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 capturing light outside the visible spectrum, for example, infrared and X-ray. The key observation in this work is Pseudocolor processing of graphical images and the images can be perceived by using different values in different layers of a color image using multicolor perception. This technique can be successfully applied to a variety of gray scale images and videos. Keywords— Pseudocolor, multicolor perception, reference grey images, image processing, computer graphics.

Multicolor Electron Microscopy for Simultaneous Visualization of Multiple Molecular Species.

Electron microscopy (EM) remains the primary method for imaging cellular and tissue ultrastructure, although simultaneous localization of multiple specific molecules continues to be a challenge for EM. We present a method for obtaining multicolor EM views of multiple subcellular components. The method uses sequential, localized deposition of different lanthanides by photosensitizers, small-mole...

Gradient-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...
