Sep 11, 2013 · Nirmala , try the following , its a very simple and efficient code to convert grayscale images to RGB using a specified colormap. It will be color, but not the original color of course. @Image Analyst: Ya not the original color, that's …

Nov 25, 2012 · Converting to grayscale generally simplifies–and often speeds up–the processing of these color images. Creating a grayscale image as a linear combination of multiple colorplanes is a common task, and one that the Image Processing Toolbox facilitates with …

To specify colors with either approach, call the desired plotting function with an output argument so you can access the individual plot objects. Then set properties on the plot object you want to change. For example, create a scatter plot with 100-point filled markers.

When converting RGB image to gray you lose color information per-pixel. If you are working on scrambling of 2D images, you can treat each channel R, G and B as an independent 2D signal, scramble each one and then combine the reconstructed signals to a color image at the end by.

Jul 29, 2009 · This can be done by using an Embedded MATLAB function block inside the subsystem. The Embedded MATLAB function would have two inputs, the signal to be tested and also the threshold to be tested against.

Aug 22, 2016 · I have a .tif file of a landmass that denotes elevation. I want to display this raster with a color ramp as opposed to a grayscale ramp. How would I do this in Matlab? I looked at the information associated with the tiff using: [Z, R] = geotiffread('Landmass.tif') which denotes the heading 'ColourType' as 'grayscale'.
