Hi

I have an image which has a lot of circles. So I have used imfindcirles and viscircles to find and visualize the circles in a figure window. Now I want to get the image as it is and store it in a variable in the program.

I tried using getimage, but it gets only the original image, without the circles marked in it.

Did you try to get cdata?

theFrame = get(gca, 'CData');

If that doesn't work, use export_fig.

I am getting an error when I am using cdata. I have attached the code below:

data = imread('coins.png');  
figure();  
imshow(data);  
[centers radii] = imfindcircles(data,[3 10], 'Sensitivity', 0.92,'Edge', 0.03);  
theFrame = get(gca, 'CData');  
figure();  
imshow(theFrame);
