MATLAB: How manually deselect an object after segmentaion

cellimage processingImage Processing Toolboximage segmentationimfindcirclesMATLABoverlapremoveoverlap

I have been doing Cell segmentation using circular hough transform. I used imfindcircles to detect cells and RemoveOverLap to remove some unwanted overlaps. everything seems to work fine but i need to give the user the ability to deselect any of cells. i have been playing around and because cell detection is based on the center and radius , if i want to delete any of the cells i need both center and radius, i could manage to get the center but no luck with radius. i need to somehow either get the radius or delete segmented cell some other way. below are the codes i am using:
image url: http://i40.tinypic.com/2hri9si.jpg
         img1 = imread('Overlap_3.jpg');
         img = rgb2gray(img1);
         threshold = graythresh(img);
         img = im2bw(img,threshold);
         img = ~img;
         img = imfill(img,'holes');
         figure, imshow(img);
         img = bwareaopen(img,150);
         %figure, imshow(img);

         [centers, radii] = imfindcircles(img,[30 50],'Sensitivity',0.95,'Edge',0.8);
         %figure, imshow(img);
         figure, imshow(img1);
         hold on
         viscircles(centers, radii,'EdgeColor','g')
         [centersNew, radiiNew]=RemoveOverLap(centers,radii,40,2);
         figure, imshow(img1);
         hold on
         viscircles(centersNew, radiiNew,'EdgeColor','g');
         length(centersNew)
thank you in advanced

Best Answer

If you use ginput, then check which of the centers is closest to that will let you know which circle the user pointed to.
