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
Split RGB Image into Its Component Channels
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])
Split Image in HSV Colorspace into Its Component Channels
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])
Input Arguments
I
— Input image
m-by-n-by-k array
Input image, specified as an m-by-n-by-k numeric array.
Data Types: single
| double
| int8
| int16
| int32
| int64
| uint8
| uint16
| uint32
| uint64
| logical
Output Arguments
c1,c2,c3,...,ck
— Output images
numeric matrix for each channel
Output images, returned as k individual numeric matrices, where k is the number of channels in the input image. The output images are the same class as the input image.
Extended Capabilities
C/C++ Code Generation
Generate C and C++ code using MATLAB® Coder™.
imsplit
supports the generation of C
code (requires MATLAB®
Coder™). For more information, see Code Generation for Image Processing.
Thread-Based Environment
Run code in the background using MATLAB® backgroundPool
or accelerate code with Parallel Computing Toolbox™ ThreadPool
.
This function fully supports thread-based environments. For more information, see Run MATLAB Functions in Thread-Based Environment.
Version History
Introduced in R2018bR2021b: Support for thread-based environments
imsplit
now supports thread-based
environments.
