How to save the image in axes in the GUI?

Hi, I have a GUI in which i need to save the image that is in the right hand side of the axes. I here by attach you the snapshot of the GUI. This is the coding for the GUI.

I couldn't find the callback function for the image in the axes. Can you please help me to figure out saving the image that is in right hand side only. Thanks...

I couln't get the image in the axes which is in right hand side. I tried in many ways to get the image:

%image2=getimage(gcf);
figure;imshow(image2);

and

 %image=getframe(h_ax1);
image2=frame2im(image);
figure;imshow(image2);,,

I am facing problems to get the image, by using the above lines i am getting the figure with complete red image but not the thresholded image.

Can you please help me in getting the image from the axes..

Thanks

You put it in the axes so you should have it and can use imwrite on it. If you really want just what's in the axes rather than the original image, then use getframe().

This is my friends coding and I couldn't find in which axes I can get the image that is in the right hand side. Can you please check that for me?

Thanks...

What happened to your friend?

[Manoj Kumar]

he has left and this is a task given by my professor to me.

[Image Analyst]

He was using imagesc() to display them, and the second image was called im. So just do

imwrite(im, fullFileName);

[Manoj Kumar]

If i use imwrite(im,fullfilename), I could save the image that I used to run the program, but not the thresholded image that I made at the right side. I want to save the image after thresholding, i.e the image you can see with the red dots on it after thresholding. You can see the thresholded image which is in the right side of the screen shot.

thanks...

When you say

threshimage=image(back);

threshimage is not an image. It's the handle to an image, in other words, a floating point number, not an actual image. Just look up the help for image() function and you'll see I'm right. But then you use it as an image afterwards which is not correct.

What is the image that is in red? I can't tell because the code is hard to follow. Is it back? Is it norm_im? Whatever it is, you have it as a variable in your program and you don't need to pull it out of the axes with getframe().

[Manoj Kumar]

I tried in this way

 image=getimage(h_ax1);

 figure;imshow(image);

to get the thresholded image, but I got this output,

I even tried with norm_im, but I am getting the segmented Image before thresholding. I need the segmentedImage after thresholding.

I don't understand how to call the image in the right side of the GUI(i think in ax_1)

Can you please run the code using these lines in the command window and help me in getting the image in the right side of the axes.

 >> im=imread('segmented.jpg');
>> imorig=imread('original.jpg');
>> manual_thresh(im,imorig);

I here by attach the code.

maybe you could solve this problem by using the following codes：

>>frame = get(get(handles.cameraAxes,'children'),'cdata');% The current displayed frame

>>save('testframe.jpg', 'frame');

cameraAxes is your axes tag in the GUI which display the image
