[Insight-users] singleValuedCostFunction vs MultiValuedCostFunction

[bertrand]

hi all

I would like two kind of cost functions in a registration process.
The first one is used as a data driven energy term ( for example an 
itkImageToImageMetric) .
The second one could be considered as  a regularization  data term ( for 
exmaple an itkPointSetToImageMetric) .

So my problem is to use two CostFunction in the same registration process.
What is the main difference between SingleValuedCostFunction and 
MultiValuedCostFunction.
Is it a good way to resolve my problem by writing a more complex 
CostFunction which can take into account a lot of SingleValuedCostFunction ?

regards,

Bertrand
