There are multiple meanings of "thresholding" that might be appropriate.
One meaning:
NewImage = YourImage >= T1 & YourImage <= T2;
Another:
NewImage = YourImage .* (YourImage >= T1 & YourImage <= T2);

NewImage = uint8(YourImage >= T1 & YourImage <= T2);
However you may wish to consider instead
NewImage = uint8(255 * (YourImage >= T1 & YourImage <= T2));
