That's not a gray scale image you attached, it's an RGB image. So try this
rgbImage = imread('C1fig.jpg');whos rgbImagesubplot(2, 1, 1);imshow(rgbImage);title('Original RGB image C1fig.jpg');axis('on', 'image');impixelinfomask = rgbImage(:, :, 1) == 0;% Extract the individual red, green, and blue color channels.
redChannel = rgbImage(:, :, 1);greenChannel = rgbImage(:, :, 2);blueChannel = rgbImage(:, :, 3);redChannel(mask) = 255;greenChannel(mask) = 0;blueChannel(mask) = 0;% Recombine separate color channels into a single, true color RGB image.
rgbImage = cat(3, redChannel, greenChannel, blueChannel);subplot(2, 1, 2);imshow(rgbImage);axis('on', 'image');impixelinfotitle('Altered RGB image');
If it really is a gray scale image, you can try this:
grayImage = imread('C1fig.jpg');if ndims(grayImage) == 3; grayImage = rgb2gray(grayImage);endwhos grayImagesubplot(2, 1, 1);imshow(grayImage);title('Original image C1fig.jpg');axis('on', 'image');impixelinfomask = grayImage == 0;% Initialize the individual red, green, and blue color channels.
redChannel = grayImage;greenChannel = grayImage;blueChannel = grayImage;redChannel(mask) = 255;greenChannel(mask) = 0;blueChannel(mask) = 0;% Recombine separate color channels into a single, true color RGB image.rgbImage = cat(3, redChannel, greenChannel, blueChannel);subplot(2, 1, 2);imshow(rgbImage);axis('on', 'image');impixelinfotitle('Altered RGB image');
