ShapeContext (LIRE API)

java.lang.Object
- net.semanticmetadata.lire.imageanalysis.features.local.shapecontext.ShapeContext

所有已实现的接口:

FeatureVector, LireFeature, LocalFeature
```
public class ShapeContext
extends java.lang.Object
implements LocalFeature
```
Created by Lukas Knoch on 16.09.15. This class represents a ShapeContext feature. The comparison for this local feature is not implemented as it is only used for creating the Shapeme descriptor.
