13.7 1:N Matching Implementation
Double click menu item “Unsupervised/Matching/1:N (Key vs. a1.txt)” and enter:
private void menuItem21_Click(object sender, System.EventArgs e)
{
bool b = this.mainMenuToAPI .unsupervised_Matching_1ToN
textBox1.Text , dataDir + "a1.txt", dataDir + "b1.txt" );
}
Here, mainMenuToAPI is an object, which will implement all functions. As we discussed earlier, the main form simply links menu items to functions in the mainMenuToAPI object. The implementation is:
public bool unsupervised_Matching_1ToN
( string key, string a1File, string b1File)
{
bool b = false;
if ( ! System.IO .File .Exists (key) )
{
appendText ( "Please enter a valid Key!\n");
return false;
}
b = this.signature_Key_Signature (key);
if ( ! b )
{
appendText ( "Key Signature computation fails!\n");
return false;
}
try
{
script.results_1N = script.unsupervisedFilter .findMatch1N ( script.imageSignature , a1File, b1File);
}
catch (Exception e)
{
appendText ( "UnsupervisedFilter 1:N Matching fails:\n"
+ e.ToString () + "\n");
return false;
}
if ( script.results_1N == null )
{
appendText ( "UnsupervisedFilter 1:N Matching fails!\n" );
return false;
}
if ( script.results_1N.getStatus () )
{
setText ( script.results_1N.toString () + "\n");
appendText ("" + script.results_1N.getNumberOfMatches () +" matches!\n");
}
else
{
appendText ( "No Match!\n");
return false;
}
}
The following code simply makes sure the key image exists:
if ( ! System.IO .File .Exists (key) )
{
appendText ( "Please enter a valid Key!\n");
return false;
}
The next section of code computes the key signature:
b = this.signature_Key_Signature (key);
The next section code makes a 1:N Match:
try
{
script.results_1N = script.unsupervisedFilter .findMatch1N ( script.imageSignature , a1File, b1File);
}
catch (Exception e)
{
appendText ( "UnsupervisedFilter 1:N Matching fails:\n" + e.ToString () + "\n");
return false;
}
The final section of code prints the 1:N Matching results:
if ( script.results_1N.getStatus () )
{
setText ( script.results_1N.toString () + "\n");
appendText ("" + script.results_1N.getNumberOfMatches () +" matches!\n");
}
else
{
appendText ( "No Match!\n");
return false;
}
