MATLAB: How to save image in axes gui

askuiputfile

hello..

i'm have a image in axes1 gui

how to save the image with uiputfile button..

Call uigetfile() to get the input filename.
Call imread() to read the input image from the disk into a variable in memory.
Process the image in whatever way you want.
Call imshow() to display the image in the axes.
Call uiputfile() to get an output filename.
Call imwrite() to save the image to disk.

If your image has annotation in the overlay (arrows, text, etc.) then use export_fig() - see the File Exchange. It's the first one you see on the File Exchange screen because it's the most downloaded function of all.

uiputfile() simply gets a filename. You still have to call imwrite() to to the actual writing to disk. Try this:

% Get the name of the file that the user wants to save.
% Note, if you're saving an image you can use imsave() instead of uiputfile().
startingFolder = userpath
defaultFileName = fullfile(startingFolder, '*.*');
[baseFileName, folder] = uiputfile(defaultFileName, 'Specify a file');
if baseFileName == 0
  % User clicked the Cancel button.
  return;
end
fullFileName = fullfile(folder, baseFileName)
imwrite(yourImageArray, fullFileName);

MATLAB: How to find out the image name of a randomly selected image and save it to workspace by PushButton

The code you show doesn't appear to be related to a GUI, so it's unclear how it relates to your question.

how does the image name (of the selected image) save itself in the workspace

Nothing saves itself. You have to explicitly store whatever information you want to keep in a variable.

In the code you show, if you want to keep the index of the random images you're using you have to store the output of randi and randperm rather than discarding them as soon as you don't need them:

files = dir('/Users/Documents/MATLAB/IR1/**/*.dcm')
num_files = numel(files);
chosen_singlefile = randi(num_files);  %keep the chosen index around
filename = files(chosen_singlefile).name;
image = dicomread(filename);
chosen_permutation = randperm(num_files);  %keep the chosen ordering around
for image_order = chosen_permutation
    k = image_order
    filename = files(k).name;
    image = dicomread(filename);
end
