−	No problem has been occurred in this module. However, the performance of this module depends on the data. If data does not have good contrast, the thresholding does not work as expected. Therefore, there should be another algorithm which helps the user to look at the grey-level values of the data in order to pick the correct threshold intervals. On the other hand, if the data is noisy, has low contrast, blurred, in this module any smoothing or reconstruction ~~methods~~ can be included before binary thresholding in order to enhance the image.	+	No problem has been occurred in this module.

	The ITK filter produces an output image whose pixels are either one of two values ( OutsideValue or InsideValue ), depending on whether of not the corresponding input image pixel lie between the two thresholds ( LowerThreshold and UpperThreshold ). Values equal to either threshold is considered to be between the thresholds.
