./indexer host port image synchrone storage id propertiesKeys propertiesValue

Example:

./indexer.sh localhost 1234 http://personalphdenis.appspot.com/images/cbir.png

./indexer.sh test 123 http://personalphdenis.appspot.com/images/cbir.png true abc 56 date,path 20141122,cbir.png

Parameters/Config

index	name	description	type
0	Host	A RetrievalServer host	String
1	Port	A RetrievalServer port	String
2	Picture URI	An image URI (File or URL)	Long
3	Synchrone (Optional)	If false, indexer just add the image on the index queue. Otherwise, the indexer will wait until the server index the image.	Boolean
4	Storage name (Optional)	The storage name. Use '###EQUITABLY###' to index image on a random storage. If you create N storage, its better to have storage with more or less the same size.	String
5	Picture id (Optional)	The image will be indexed with this id. An id must be unique for a server.	Long
6	Picture properties keys (Optional)	A list of properties keys (comma sep) e.g.: ' name,date,path'	String
7	Picture properties values (Optional)	A list of properties value (comma sep) e.g.: ' 123,test,2014/10/31,/home/myself/mypicture.png'	String

Code

Object Server

public RetrievalIndexerLocalStorage(Storage storage, boolean synchronous)

• storage: index name where the image will be indexed.
• synchronous: if false, indexer just add the image on the index queue You can use the RetrievalIndexerDistantStorage to index a picture in a distant server.

Example

boolean sync = true;
RetrievalServer server = ...

RetrievalIndexer index = new RetrievalIndexerLocalStorage(server.getStorage(“0”),sync); // server.getNextStorage() to take a random storage

Distant Server

public RetrievalIndexerDistantStorage(String host, int port, String storage, boolean synchronous)

The index method takes the image (File, URL or BufferedImage), an id (optional) and a properties map (optional)
