imsplit
Split multichannel image into its individual channels
Description
[
returns a set of k images representing the individual channels in the
k-channel image c1,c2,c3,...,ck] = imsplit(I)I.
Examples
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.
montage({h,s,v},'Size',[1 3])
