matlab invert image

To invert an image in MATLAB, you can use the imcomplement function. Here's an example of how to do it:

% Read the image
image = imread('your_image.jpg');

% Invert the image
inverted_image = imcomplement(image);

% Display the original and inverted images
title('Original Image');
title('Inverted Image');

In this code, we first read the image using the imread function and store it in the variable image. Then, we use the imcomplement function to invert the image and store the result in the variable inverted_image. Finally, we display both the original and inverted images using the imshow function and provide appropriate titles for each subplot.

Note that you need to replace 'your_image.jpg' with the path or filename of your actual image. Also, make sure to have the Image Processing Toolbox installed in MATLAB, as the imcomplement function is part of this toolbox.

By following these steps, you should be able to invert an image in MATLAB.
