white red black; cyan green yellow; black blue white image in matlab

To achieve the desired result, we need to convert the given image to RGB format and then manipulate the color channels in MATLAB. Here's the code snippet to do so:


main.m
% Read the input image
img = imread('input_image.png');

% Convert the image to RGB format
img_rgb = ind2rgb(img, colormap('gray'));

% Manipulate the color channels
red_channel = img_rgb(:, :, 1);
green_channel = img_rgb(:, :, 2);
blue_channel = img_rgb(:, :, 3);

% Create the output image by rearranging the channels
output_img = zeros(size(img_rgb));
output_img(:, :, 1) = white .* red_channel + cyan .* green_channel + black .* blue_channel;
output_img(:, :, 2) = green .* red_channel + yellow .* green_channel + blue .* blue_channel;
output_img(:, :, 3) = black .* red_channel + white .* green_channel + white .* blue_channel;

% Display the output image
imshow(output_img);

In the above code, we first read the input image and convert it to RGB format using the "ind2rgb" function. Then, we extract the individual color channels from the RGB image and manipulate them using the given color matrices. Finally, we create the output image by rearranging the color channels and display it using the "imshow" function.

Note: The color matrices used in this code snippet are assumed to be defined earlier in the code.
