You can use “viscircles” function to overlay detected circles on the image and “imwrite” to write image data.

Please refer to the sample code below for better understanding:

img2 = imread('image.png');
hold on;

[centers, radii, metric] = imfindcircles(img2, [15 416]);
viscircles(centers, radii, 'EdgeColor', 'b');

frame = getframe(gca);
imwrite(frame.cdata, 'annotated_image.jpg');
hold off;

The “getframe” function captures the content of the current figure window. “imwrite” function then saves the captured image as a new file in the current folder.

You can also refer to the below documentation link on “imwrite” for your reference:
