Hello,<br><br> I am a new user to ITK and am running through some of the webinars and examples to get accustomed to how to properly use and work with ITK but I am running into a small hang up. Many of the examples have me pass in arguments into the filters that are relevant to the output of the filters but yet I can find no where that explains what these arguments do or what they are. For Example, in one of the practice examples I am working with the Sgmoid Image Filter. Once I fix the code in the *.cxx file, I compile it, and then execute it and this particular filter asks for the arguments inputImageFile, outputFileImage, alpha, and beta. I know what the first two arguments are but I would like to understand specifically what the alpha and beta parameters are doing. I have been searching on the Doxygen wiki and can only find these arguments in the itkSgmoidImageFIlter.h file but no other information. Anyone know where I can educate myself with these filter arguments (not just the alpha and beta specifically)? Thanks for reading this and trying to help me out.<br>
