Class CompleteSift_MT

java.lang.Object

boofcv.alg.feature.detdesc.CompleteSift

boofcv.alg.feature.detdesc.CompleteSift_MT

public class CompleteSift_MT
extends CompleteSift

Concurrent implementation of CompleteSift. The part which it makes concurrent is computing the descriptors. Everything else is identical.
