## Implementing LSA " indexing image" in JAVA

I am a student working on project'indexing image' using the LSA modele in JAVA. Please, I want to ask you about how to show the result of the distance between the images of the base and the images of the test. I tried all methods but it did not work. Is there any help?

this.Appliquer_LSA();

}

public double euclid(double [] req, double [] im)
{
double dist=0.0;
for (int i=0;i<req.length;i++)
dist=dist+((im[i]-req[i])*(im[i]-req[i]));
dist=Math.sqrt(dist);
return dist;
}

public void Appliquer_LSA()
{

int [][] resultats=new int [20][140];
double [][] distances=new double[20][140];

Matrix train=new Matrix(this.term_doc);
Matrix test=new Matrix(this.term_doc_test);
Matrix s=train.transpose();
Matrix t=test.transpose();

SingularValueDecomposition svd=new SingularValueDecomposition(s);

Matrix U=svd.getU();//docs
Matrix S=svd.getS();
Matrix V=svd.getV();//mots
System.out.println("Affichage des distances");
int j=0;//nombre de requetes
while (j<20)
{
System.out.println("Req N°: "+j);
double [][] requ=new double [20][1];

for (int i=0;i<20;i++) requ[i][0]=this.term_doc_test[i][j];
Matrix req=new Matrix(requ);

Matrix r=req.transpose().times(V.times(S));//
//  System.out.println("r:  "+r.getRowDimension());
double [] requet=new double[20];
for (int k=0;k<20;k++) requet[k]=r.get(0, k);

for (int x=0;x<140;x++)
{
double [] image=new double[20];
for (int k=0;k<20;k++) image[k]=U.get(x, k);
distances[j][x]=this.euclid(requet, image);
//tri des distances

}
//       int [] res=Arrays.sort(distances[j]);
int [] res=this.tri_1(distances[j]);
for (int g=0;g<res.length;g++)
//          System.out.println(g+"***lguit*****************"+res[g]);
for (int f=0;f<res.length;f++)
resultats[j][f]=res[f];
// for (int y=0;y<distances.length;y++) System.out.println("Distances: "+distances[y]);
j++;
}
String text="";
for (int f=0;f<distances.length;f++)
for (int g=0;g<distances[0].length;g++)
text=text+distances[f][g]+"\n";
