How do you make gray in Matlab?
I = rgb2gray( RGB ) converts the truecolor image RGB to the grayscale image I . The rgb2gray function converts RGB images to grayscale by eliminating the hue and saturation information while retaining the luminance. If you have Parallel Computing Toolbox™ installed, rgb2gray can perform this conversion on a GPU.
How do I set RGB color in Matlab?
Using RGB triplets to change colors One can specify colors using a vector that gives the RGB triple where in MATLAB, each of the three values are numbers from 0 to 1. Usually RGB colors have values from 0 to 255. You can use those numbers and divide the vector by 255 to use within MATLAB.
What is RGB color Matlab?
