how to save the image to which viscircles (centers, radii) apply?

I'm new to Matlab and I have a problem. The binarized image is saved and the one I want to save is the image that viscircles applies (centers, radii).

for i=1:totalimag

imag{i}=importdata(fullfile(ruta,imag{i}),' ');

%binarizar img

imgbn{i}=rgb2gray(imag{i});

[centers,radii] = imfindcircles(imgbn{i},[5 30],'ObjectPolarity','Dark',...

'Sensitivity',0.92);

imshow(imgbn{i})

%se dibujan círculos en imgbn

h{i} = viscircles(centers,radii);

eval(sprintf(' var%d = centers,radii', i))

carpeta='C:\Users\angel\Desktop\programas\Matlabt';

namefile= [carpeta, '\imacept', num2str(i), '.jpg'];

imwrite(imgbn{i},namefile)

end

Hi Angelo,

To save the images with the circles drawn in it you can capture the figure with the circles and save it.

Please refer to the below code:

hFig = figure; 
imshow(imgbn{i});
hold on;
viscircles(centers, radii);
saveas(hFig, filename); 
close(hFig); 

The above code will display the image by creating a figure window. “saveas” is used to save the current figure with the circles drawn on it with the file “filename”. Specify the file name as a character vector or string that includes a file extension. If not, then “saveas” saves the figure to a FIG-file.

I am also attaching documentation link on “saveas” for your reference:

Hope this will be helpful!
