[Insight-users] Mutexes

[Luis Ibanez]

Hi Brady,


Applying Mutual Exclusion on a per-pixel basis does not seem to
be a good idea. It most likely be very expensive in computation
time.

You may want to profile the time of Mutex and the FastMutex in
your platform, in order to make an informed decision...


What is your motivation for using a mutual exclusion lock on
every pixel ?


You may find in ITK better methods to solve your image processing
problem.


    Please let us know,



        Thanks


             Luis
