This error was occurred when I was testing the Example of the " Multilevel image thresholds using Otsu's method" in Matlab 2015a. Can you please tell me why this error occurred and how to solve this?

link to the example : -

openExample('images/CompareThresholdingEntireImageVersusPlanebyplaneThresholExample')
>> I = imread('circlesBrightDark.png');
>> imshow(I)
Warning: Image is too big to fit on screen; displaying at 67% 
> In images.internal.initSize (line 71)
  In imshow (line 305) 
>> axis off
>> title('Original Image')
>> thresh = multithresh(I,2);
>> seg_I = imquantize(I,thresh);
>> RGB = label2rgb(seg_I);
