Interface SpatialVectorAggregator<FEATURE extends FeatureVector,LOCATION extends Location,BOUNDS>

Type Parameters:

FEATURE - The type of FeatureVector of the LocalFeatures that can be processed.

LOCATION - The type of Location of the LocalFeatures that can be processed.

BOUNDS - The spatial bounds in which the LocalFeatures were extracted.

All Known Implementing Classes:

BlockSpatialAggregator, PyramidSpatialAggregator

public interface SpatialVectorAggregator<FEATURE extends FeatureVector,LOCATION extends Location,BOUNDS>

Interface describing an object that can convert a list of local features from a single image into an aggregated vector form, using both the featurevector and spatial location of each local feature. An example use is to create aggregate feature vectors that encode go beyond simple VectorAggregators in that they additionally encode spatial information.

FeatureVector	aggregate(List<? extends LocalFeature<? extends LOCATION,? extends FEATURE>> features, BOUNDS bounds) Aggregate the given features into a vector.

Method Detail

aggregate

FeatureVector aggregate(List<? extends LocalFeature<? extends LOCATION,? extends FEATURE>> features,
                        BOUNDS bounds)

Aggregate the given features into a vector. The features are assumed to have spatial locations within the given bounds; typically this might be the bounds rectangle of the image from which the features were extracted.

Parameters:

features - the features to aggregate

bounds - the bounds in which the features were extracted

Returns:

the aggregated vector
