I came across the codes to detect yellow and white colors from a live video. But, these are the codes that allow to detect only one color, either of them. If at all I want to detect multiple colors,yellow and white in this case, hoe can I do it?

Try this:
% Extract the individual red, green, and blue color channels.
redChannel = rgbImage(:, :, 1);greenChannel = rgbImage(:, :, 2);blueChannel = rgbImage(:, :, 3);% Now swap around in any way you want.
newRedChannel = greenChannel;newGreenChannel = blueChannel; newBlueChannel = redChannel;% Recombine separate color channels into a single, true color RGB image.
NewRgbImage = cat(3, newRedChannel, newGreenChannel, newBlueChannel);Try this:
rgbImage = imread('image.jpeg');subplot(2, 1, 1);imshow(rgbImage);% Extract the individual red, green, and blue color channels.
redChannel = rgbImage(:, :, 1);greenChannel = rgbImage(:, :, 2);blueChannel = rgbImage(:, :, 3);% Get the yellow mask
yellowMask = redChannel > 128 & greenChannel > 128;% Get the white mask
whiteMask = redChannel > 128 & greenChannel > 128 & blueChannel > 128;% Make yellow mask green
redChannel(yellowMask) = 0;greenChannel(yellowMask) = 255;blueChannel(yellowMask) = 0;% Make the white mask blue
redChannel(whiteMask) = 0;greenChannel(whiteMask) = 0;blueChannel(whiteMask) = 255;% Recombine separate color channels into a single, true color RGB image.
rgbImage2 = cat(3, redChannel, greenChannel, blueChannel);subplot(2, 1, 2);imshow(rgbImage2);
