Thanks for suggestion. I swapped the parameters of the function call.

Thanks for reporting. I have added the missing example image. Let me know if you have more issues.

You can try to increase the size of the sliding window. Don't be afraid to increase the windows size to hundreds to hundreds pixels - the window should be bigger than the biggest symbol in the image.

Or you can try the post-processing step from Yanowitz and Bruckstein's binarization method: http://www.mathworks.com/matlabcentral/fileexchange/41786-remove-ghosts-from-binarized-images

Basically it looks at the edge of each foreground object. And if the average gradient along the edge is small, it concludes that it's false foreground object and deletes the object.

19 Apr 2013 Gray image thresholding using the Triangle Method Computes a threshold the Triangle method. Author: Bernard Panneton

It's giving different threshold than triangle method in ImageJ applied to the same image.
