I've been learning about blind signal separation.
I have noticed that there are a number of algorithms for performing blind signal separation. (eg: Independent component analysis)
Which begs the question, are there any 'non-blind' signal separation algorithms?
I've been searching for a while and I haven't found anything. Nothing is listed on the wiki page and I've never noticed any in open libraries such as open CV.
I'm not even sure what search terms to look for.
