15.9 1:N Matching ImplementationDouble click menu item “NeuralFilter/Matching/1:N (Key vs. a1.tx)” and enter: private void menuItem66_Click(object sender, System.EventArgs e) { this.mainMenuToAPI .neuralFilter_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 neuralFilter_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.neuralFilter.findMatch1N ( script.imageSignature, a1File, b1File); } catch (Exception e) { appendText ( "NeuralFilter 1:N Matching fails:\n" + e.ToString () + "\n"); return false; } if ( script.results_1N == null ) { appendText ( "NeuralFilter 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; }
return createFile (key, b1File); } 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.neuralFilter.findMatch1N ( script.imageSignature, a1File, b1File); } catch (Exception e) { appendText ( "NeuralFilter 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; }
