Media search engines built implemented in Java using Tensorflow

The current media search engine supports indexing and queries over images and audio

Image Search Engine

The sample codes below shows how to index and search for image file using the ImageSearchEngine class:

import com.github.chen0040.tensorflow.commons.FileUtils;
import com.github.chen0040.tensorflow.search.models.ImageSearchEngine;
import com.github.chen0040.tensorflow.search.models.ImageSearchEngineInception;
import com.github.chen0040.tensorflow.search.models.ImageSearchEntry;

import java.io.File;
import java.util.List;

public class Demo {
    public static void main(String[] args) {
        ImageSearchEngine searchEngine = new ImageSearchEngineInception();
        if(!searchEngine.loadIndexDbIfExists()) {
            searchEngine.indexAll(FileUtils.getImageFiles("image_samples", ".png"));
            searchEngine.saveIndexDb();
        }
        
        int pageIndex = 0;
        int pageSize = 20;
        boolean skipPerfectMatch = true;
        for(File f : FileUtils.getImageFiles("image_samples", ".png")) {
            System.out.println("querying similar image to " + f.getName());
            List<ImageSearchEntry> result = searchEngine.query(f, pageIndex, pageSize, skipPerfectMatch);
            for(int i=0; i < result.size(); ++i){
                System.out.println("# " + i + ": " + result.get(i).getPath() + " (distSq: " + result.get(i).getDistanceSq() + ")");
            }
        }
    }
}

Audio Search Engine

The sample codes below shows how to index and search for audio file using the AudioSearchEngine class:

import com.github.chen0040.tensorflow.commons.FileUtils;
import com.github.chen0040.tensorflow.search.models.AudioSearchEngine;
import com.github.chen0040.tensorflow.search.models.AudioSearchEngineImpl;
import com.github.chen0040.tensorflow.search.models.AudioSearchEntry;

import java.io.File;
import java.util.List;

public class Demo {
    public static void main(String[] args) {
        AudioSearchEngine searchEngine = new AudioSearchEngine();
        if(!searchEngine.loadIndexDbIfExists()) {
            searchEngine.indexAll(FileUtils.getAudioFiles("music_samples", ".au"));
            searchEngine.saveIndexDb();
        }
        
        int pageIndex = 0;
        int pageSize = 20;
        boolean skipPerfectMatch = true;
        File f = new File("mp3_samples/example.mp3");
        System.out.println("querying similar music to " + f.getName());
        List<AudioSearchEntry> result = searchEngine.query(f, pageIndex, pageSize, skipPerfectMatch);
        for(int i=0; i < result.size(); ++i){
            System.out.println("# " + i + ": " + result.get(i).getPath() + " (distSq: " + result.get(i).getDistanceSq() + ")");
        }
    }
}
