there are no examples of use in the documentation for sift function.-or any other function

dont know what to include.and how to work it.
i am specificall interested in the sifts feature that does not use detector but ihe user gives the points and it runs the descriptor for it,or finds the orientation also.
can you help me with that? there is some parameteer i have to add i was told.but dont know which. as i cant even use the simple sift.

this is doing using it verydifficult for all the people that arent you!- havent writen the code.
image me writing a funtion, and tell you use it these are the parameters. first you dont know what to include in the begining.second you dont understand exactly the parameters.
third i have in the parameters a function i say handelr. but dont tell you what this sould be.
an working example is illuminating.
tou spend much time to say what every parameter is.
when you could just write an example and next to it remarks about the parameters.
