Image Processing Toolboximfindcircle

i have used imfindcircle to find circle object in image. do you know how to save the image result of the circle object detected?

dear raja, most probable you are using viscircles to highlighter the circles, this commands uses superimposing of graph over the image not actually changes the pixel values.
use this program to save circles with markings
clear all
close all
clc
A = imread('coins.png');
figure(1)
imshow(A)
drawnow
[centers, radii, metric] = imfindcircles(A,[15 30]);
centersStrong5 = centers(1:5,:);
radiiStrong5 = radii(1:5);
metricStrong5 = metric(1:5);
%/////// this command makes plot superimpose on the image not the pixels change permanently 
viscircles(centersStrong5, radiiStrong5,'EdgeColor','b');
imwrite(A,'image_out_1.jpg');
%/////// for changing the values of the pixels in the image for making circle //////
B(:,:,1)=A;
B(:,:,2)=A;
B(:,:,3)=A;
for i=1:length(radiiStrong5)
    theta=0:1:360;
    r=round(centersStrong5(i,1) + radiiStrong5(i)*sin(theta));
    c=round(centersStrong5(i,2) + radiiStrong5(i)*cos(theta));
      for j=1:length(r)
          B(c(j),r(j),:)=[0 0 255];
      end
  end
  figure(2)
  imshow(B)
  drawnow
imwrite(B,'image_out_2.jpg');
