save an image using imwrite in matlab

To save an image in MATLAB, you can use the imwrite function which allows you to save the image as different file formats such as PNG, JPG, GIF, etc.

Here's an example code snippet:

main.m
% Read an example image
img = imread('example.png');

% Save the image as a JPG file
imwrite(img, 'example.jpg', 'jpg');

% Save the image as a PNG file with 80% compression quality
imwrite(img, 'example_compressed.png', 'png', 'Compression', 80);
248 chars
9 lines

In this code, we first read an example image using the imread function. We then save the image as a JPG file using imwrite with a specified file name and file format.

We can also specify optional parameters, such as the compression quality for PNG files, which is set to 80% in this example.
