13.5   N:N Matching Implementation

Double click menu item “Unsupervised/Matching/N:N (a1.txt vs. a1.txt)” and enter:

      private void menuItem23_Click(object sender, System.EventArgs e)


              this.mainMenuToAPI .unsupervised_Matching_NToM

                  (dataDir + "a1.txt", 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_NToM

                ( string a1File, string a2File, string b1File)




                    script.unsupervisedFilter .findMatchNM

                         ( a1File, a2File, b1File);


                    catch (Exception e)


                        appendText (  e.ToString () + "\n");

                        return false;


                    return true;


In this statement, the script object contains all of the objects required for the ImageFinder project. In particular, “script.unsupervisedFilter” is the unsupervised filter object. The parameters, (a1File, a2File, b1File), indicate all signatures in a1File will be matched against all signatures in a2File. After completion of the matching, the results will be stored in a file specified by the last parameter, b1File.
