Package boofcv.alg.feature.detdesc

Class CompleteSift

java.lang.Object

boofcv.alg.feature.detdesc.CompleteSift

Direct Known Subclasses:

CompleteSift_MT

public class CompleteSift
extends Object

SIFT combined together to simultaneously detect and describe the key points it finds. Memory is conserved by only having one octave of the scale-space in memory at any given time.
