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;

                    }
