Hi All

Sorry a little new to this ......

When I use ImageJ: Adjust: Threshold on 16-bit medical image volume dataset and set the threshold to a specific upper and lower limit value (when set to default and red or b/w in the tabs) it appears the actual thresholding is not based exactly on the exact limits I have set but appear to be based on a wider range than the ones I have set.

Should the simple threshold be based just on my upper and lower limits as I input ?

Please let me know if I am doing this wrong.

kind regards
bal
