Image = getframe(gcf);
imwrite(Image.cdata, 'mask_image.jpg');
Another method:
printf(gcf, '-djpeg100', 'mask_image.jpg', '-r0');
But the later is not guaranteed to have exactly the same size. There are some rounding effects between the units of the figure and the pixel resolution.

You could just use the built-in "imwrite" function to save any loaded image, or specifically a 'uint8' file, to a file of any choice:
Image = imread("ImageName.jpg");
imwrite(Image, "NewImageName.jpg");
This code doesn't return the max resolution of the file, but there is a parameter for that:
Image = imread("ImageName.jpg");
imwrite(Image, "NewImageName.jpg", "Quality", 100)
The interval of values for quality is between 0 and 100, inclusive, with the result being self-explanatory
Other information could be found in matlab by typing the input "help imwrite" and doing some reading...
There's also a text file called libtiffcopyright.txt, but I don't know where to find that
