Package boofcv.alg.scene.bow

Class InvertedFile

java.lang.Object

org.ddogleg.struct.DogArray_I32

boofcv.alg.scene.bow.InvertedFile

All Implemented Interfaces:

DogArrayPrimitive<DogArray_I32>

public class InvertedFile
extends DogArray_I32

The inverted file is a list of images that were observed in a particular node. Images are referenced by array index. This class extends DogArray_I32 to remove the need to store an additional java object. might be pre-mature optimization.
