EmguCV探测器如何与EmguCV DescriptorExtractors相关？

Question

Reading EmgCV docs cant quite understand: what detectors can be used with which DescriptorExtractors?

Here it is said:

You can use it with the FREAK descriptor that is scale invariant. Just replace the BriefDescriptorExtractor with Freak and it should do the trick.

does it mean that not all detectors are compatable to DescriptorExtractors? If yes where one can find comparisons and documentation on topic?
