imsplit

Read an RGB image into the workspace and display the image.

I = imread('peppers.png');
imshow(I)

Split the image into its component red, green, and blue channels.

[r,g,b] = imsplit(I);

Display the three color channels as a montage. Red peppers have a signal predominantly in the red channel. Yellow and green peppers have a signal in both the red and green channels. White objects, such as the garlic in the foreground, have a strong signal in all three channels.

montage({r,g,b},'Size',[1 3])

Read an RGB image into the workspace and display the image.

rgbImage = imread('peppers.png');
imshow(rgbImage)

Convert the RGB image to the HSV colorspace by using the rgb2hsv function.

hsvImage = rgb2hsv(rgbImage);

Split the HSV image into its component hue, saturation, and value channels.

[h,s,v] = imsplit(hsvImage);

Display the three channels as a montage.
