Class SearchThread

java.lang.Object
  java.lang.Thread
      retrieval.SearchThread

All Implemented Interfaces:

java.lang.Runnable

public class SearchThread
extends java.lang.Thread

A thread to handle the parsing of one skeleton and comparing it with PSGM to the query object (passed as "ready-to-use" skeleton object). The result is saved to a priority queue, passed by reference, automatically ordering all results of all concurrent threads according to their descending similarity.

See also SimilaritySearch.

Constructor Detail

SearchThread

public SearchThread(SkeletonObject so,
                    SkeletonObject so_flipped,
                    java.lang.String skeletonfilename1,

Method Detail

getSkeletonfilename2

public java.lang.String getSkeletonfilename2()

Returns:

the skeletonfilename2

getObjectfilename2

public java.lang.String getObjectfilename2()

Returns:

the objectfilename2

run

public void run()

Start the search thread. The second skeleton object, specified by the paths to skeleton and shape image, is parsed. Then, PSGM is applied to this second skeleton object and the query object. The result is saved to a priority queue, automatically ordering the results according to their similarity to the query object.

Specified by:

run in interface java.lang.Runnable

Overrides:

run in class java.lang.Thread

getObjectfilename1

public java.lang.String getObjectfilename1()

Returns:

the objectfilename1

getSkeletonfilename1

public java.lang.String getSkeletonfilename1()

Returns:

the skeletonfilename1
