I have little question. I have nine images of the brain on one figure window. How to extract single image to new figure window from multi-image figure window?
Best regards,

If you have any more questions, then attach your image and code to read it in with the paperclip icon after you read this:
Are they in different subplot axes on one figure, or are all 9 images just stitched together in a single image and shown in a single image? We don't know because you forgot to show us.

fig = gcf; % Current figure
ax = findall(fig, 'type', 'axes');
for i = 1 : numel(ax)
figH = gobjects(1, numel(ax));
figH(i) = figure();
ax(i).Parent = figH(i);
ax(i).Position = [0.1300 0.1100 0.7750 0.8150];
% exportgraphics(ax(i), sprintf("Picture %d.jpg", i));

Where are the image(s)?
Are they in a figure window on screen? If so, how did they get there? If you have the code that created the figure window, then use the images that you put into the figure instead of trying to extract them from the figure. If the image itself is composed of multiple frames, then maybe it needs to be split in some manner.
If the only thing you have is the figure from a .fig file, then finding the images depends on how exactly they're being displayed in the figure.
If the only thing you have is a screenshot of a figure window, then use imcrop() and know that all you're getting is a degraded facsimile of whatever the original image used to be.
Depending on what you have (code that creates a figure, a fig file, or a raster image file) include that. The PDF doesn't really indicate what you have, and it also can't be used in any demonstration of a solution.

You should update your question or post a new one with clear details and an example of picture you want to extract.
