image enhancementimage processingImage Processing Toolbox

how can i enhance the red, green and blue color of an object inside an image in order to make the colour look more vivid for easy detection.

Convert to hsv colorspace with rgb2hsv. Then multiply the S channel by some factor, then go back to rgb color space with hsv2rgb().

Try this to create a grayscale image:

whiteImage = 255 * ones(N, M, 'uint8');
imshow(whiteImage);

To create an RGB image, try this:

whiteImage = 255 * ones(480, 640, 3, 'uint8');
imshow(whiteImage);

clear; clc;
I = imread('cameraman.tif');
imagesc(I); colormap(jet); colorbar;
