Imshow() To show our image, we the imshow() or imagesc() command. The imshow() command shows an image in standard 8-bit format, like it would appear in a web browser.

The imagesc() command displays the image on scaled axes with the min value as black and the max value as white. Using imshow(): Using imagesc(): We can check the RGB values with (x,y) coordinates of a pixel: • Select 'Data Cursor' icon from the top menu • Click the mouse on the image Notice each pixel is a 3-dimensional vector with values in the range [0,255]. The 3 numbers displayed is the amount of RGB. Actually, a color image is a combined image of 3 grayscale images. So, we can display the individual RGB components of the image using the following script: subplot(131); imagesc(img(:,:, 1)); title('Red'); subplot(132); imagesc(img(:,:, 2)); title('Green'); subplot(133); imagesc(img(:,:, 3)); title('Blue'); We we issue a command colormap gray, the picture turns into a grayscale: >>colormap gray Want to play more? Then, let's make a new image that has more blue by quadrupling the component.

The standard image format is uint8 (8-bit integer), which may not like arithmetic operation and could give us errors if we try mathematical operations. So, we may want to do image processing by casting our image matrix to double format before we do our math. Then we cast back to uint8 format at the end, before displaying the image. Subplot(211); imshow(img); title('Normal RGB'); subplot(212); blue_img = double(img); blue_img(:,:,3) = 4*blue_img(:,:,3); blue_img = uint8(blue_img); imshow(blue_img); title('RG 4*B').
