Double Thresholding

HI, Can someone show me an example how to apply double thresholding method, were you get to choose T1 and T2 values... ?

Show us an example of what you want. You may just answer your own question trying to explain it in type.

There are multiple meanings of "thresholding" that might be appropriate.

One meaning:

NewImage = YourImage >= T1 & YourImage <= T2;

Another:

NewImage = YourImage .* (YourImage >= T1 & YourImage <= T2);

Thank you, the first one was the one I was looking for. Also, now my image has class 'logical'. I will need to make further work with this image, how do I convert it ? back to uint8 ?

[Walter Roberson]

NewImage = uint8(YourImage >= T1 & YourImage <= T2);

However you may wish to consider instead

NewImage = uint8(255 * (YourImage >= T1 & YourImage <= T2));

You are a life saver !

Second one worked, first returned black image..
