Here, your very own Blob remover:

function removeBlob
  I = bwlabel(imfill(imread('coins.png')>100,'holes'));
  h = imshow(label2rgb(I,jet(numel(unique(I(:)))),[0 0 0]));
  set(h,'buttondownfcn',{@removeIt,I})
end
function removeIt(src,~,I)
  cp = round(get(get(src,'parent'),'currentpoint'));
  val = I(cp(3),cp(1));
  I(I==val) = 0;
  set(src,'cdata',bsxfun(@times,uint8(logical(I)),get(src,'cdata')));
end
