方法详细资料

extractLocalFeatures

public LocalFeatureExtractor extractLocalFeatures(java.awt.image.BufferedImage image,
                                                  LocalFeatureExtractor localFeatureExtractor)

Images are resized so as not to exceed the DocumentBuilder.MAX_IMAGE_DIMENSION, after that features are extracted using the given localFeatureExtractor.

参数:

image - is the image

localFeatureExtractor - selected local feature extractor

返回:

the input localFeatureExtractor

createLocalDescriptorFields

public org.apache.lucene.document.Field[] createLocalDescriptorFields(java.util.List<? extends LocalFeature> listOfLocalFeatures,
                                                                      ExtractorItem extractorItem,
                                                                      java.util.LinkedList<Cluster[]> listOfCodebooks)

Creates the Lucene Fiels with the vector representation of list of local features.

参数:

listOfLocalFeatures - is the list of local features.

extractorItem - is the extractor that was used to extract the features.

listOfCodebooks - is the list which can contain one or more codebooks to be used for the aggregation of the local features.

返回:

Lucene Fields with the vector representation of the list of local features.

createDescriptorFields

public org.apache.lucene.document.Field[] createDescriptorFields(java.awt.image.BufferedImage image)

从接口复制的说明: DocumentBuilder

Creates the feature fields for a Lucene Document without creating the document itself.

指定者:

createDescriptorFields 在接口中 DocumentBuilder

参数:

image - the image to analyze.

返回:

Lucene Fields with the vector representation of the selected image.

createDocument

public org.apache.lucene.document.Document createDocument(java.awt.image.BufferedImage image,
                                                          java.lang.String identifier)

从接口复制的说明: DocumentBuilder

Creates a new Lucene document from a BufferedImage. The identifier can be used like an id (e.g. the file hashFunctionsFileName or the url of the image)

指定者:
