Hi. I dont; understand how use if conditionals in wolfram.
If NeedOtsu is true I should use Binirize, If NeedOtsu is false I should use my function.
I tryed to use this but there is Error:
Tag Binarize in Binarize[]/;True is Protected. >>
What is wrong?

It depends on what syntax you are using. You can try something like this:

myProcedure /; NeedOtsu := Binarize[something];
myProcedure /; Not[NeedOtsu] := myFunction[something]

Hello Dmitry,

At the risk of proposing the obvious, have you tried:

myProcedure[something_]:=If[NeedOtsu,Binarize[something],myFunction[something]]

?
