指紋識別系統

Question

IM使用VS2008和SourceAFIS 1.1 IM無法訪問任何的方法可以幫助我的人入門 他們（SourceAFIS）給了我們以下的樣品的Program.cs 我想可一個應用程序，它首先註冊用戶，然後在用戶註冊時識別它們。

namespace Sample 
{ 
    public class Program 
    { 
     // Inherit from Fingerprint in order to add Filename field 
     [Serializable] 
     class MyFingerprint : Fingerprint 
     { 
      public string Filename; 
     } 

     // Inherit from Person in order to add Name field 
     [Serializable] 
     class MyPerson : Person 
     { 
      public string Name; 
     } 

     // Initialize path to images 
     static readonly string ImagePath = Path.Combine(Path.Combine("..", ".."), "images"); 

     // Shared AfisEngine instance (cannot be shared between different threads though) 
     static AfisEngine Afis; 

     // Take fingerprint image file and create Person object from the image 
     static MyPerson Enroll(string filename, string name) 
     { 
      Console.WriteLine("Enrolling {0}...", name); 

      // Initialize empty fingerprint object and set properties 
      MyFingerprint fp = new MyFingerprint(); 
      fp.Filename = filename; 
      // Load image from the file, fp.BitmapImage makes a copy of the image, so that we can dispose it afterwards 
      Console.WriteLine(" Loading image from {0}...", filename); 
      using (Image fromFile = Bitmap.FromFile(filename)) 
       using (Bitmap bitmap = new Bitmap(fromFile)) 
        fp.BitmapImage = bitmap; 
      // Above update of fp.BitmapImage initialized also raw image in fp.Image 
      // Check raw image dimensions, Y axis is first, X axis is second 
      Console.WriteLine(" Image size = {0} x {1} (width x height)", fp.Image.GetLength(1), fp.Image.GetLength(0)); 

      // Execute extraction in order to initialize fp.Template 
      Console.WriteLine(" Extracting template..."); 
      Afis.Extract(fp); 
      // Check template size 
      Console.WriteLine(" Template size = {0} bytes", fp.Template.Length); 

      // Initialize empty person object and set its properties 
      MyPerson person = new MyPerson(); 
      person.Name = name; 
      // Add fingerprint to the person 
      person.Add(fp); 

      return person; 
     } 

     static void Main(string[] args) 
     { 

      // Initialize SourceAFIS 
      Afis = new AfisEngine(); 

      // Enroll some people 
      List<MyPerson> database = new List<MyPerson>(); 
      database.Add(Enroll(Path.Combine(ImagePath, "candidate1.tif"), "Fred Flintstone")); 
      database.Add(Enroll(Path.Combine(ImagePath, "candidate2.tif"), "Wilma Flintstone")); 
      database.Add(Enroll(Path.Combine(ImagePath, "candidate3.tif"), "Barney Rubble")); 

      // Save the database to disk and load it back, just to try out the serialization 
      BinaryFormatter formatter = new BinaryFormatter(); 
      Console.WriteLine("Saving database..."); 
      using (Stream stream = File.Open("database.dat", FileMode.Create)) 
       formatter.Serialize(stream, database); 
      Console.WriteLine("Reloading database..."); 
      using (FileStream stream = File.OpenRead("database.dat")) 
       database = (List<MyPerson>)formatter.Deserialize(stream); 

      // Enroll visitor with unknown identity 
      MyPerson probe = Enroll(Path.Combine(ImagePath, "probe.tif"), "Visitor #12345"); 

      // Look up the probe using Threshold = 10 
      Afis.Threshold = 10; 
      Console.WriteLine("Identifying {0} in database of {1} persons...", probe.Name, database.Count); 
      MyPerson match = Afis.Identify(probe, database); 





      // Null result means that there is no candidate with similarity score above threshold 
      if (match == null) 
      { 
       Console.WriteLine("No matching person found."); 
       return; 
      } 
      // Print out any non-null result 
      Console.WriteLine("Probe {0} matches registered person {1}", probe.Name, match.Name); 

      // Compute similarity score 
      float score = Afis.Verify(probe, match); 
      Console.WriteLine("Similarity score between {0} and {1} = {2:F3}", probe.Name, match.Name, score); 
     } 
    } 

Answer 1

 // Initialize SourceAFIS 
     if (Afis == null) Afis = new AfisEngine(); 

     // Enroll fitst identity 
     Fingerprint f = new Fingerprint(); 
     f.AsBitmap = (Bitmap)pictureBoxFinger.Image; 

     Person probe = new Person(); 
     probe.Fingerprints.Add(f); 
     Afis.Extract(probe); 

     // Enroll second identity    
     Fingerprint f2 = new Fingerprint(); 
     f2.AsBitmap = (Bitmap)pictureBoxVerify.Image; 
     Person match = new Person(); 
     match.Fingerprints.Add(f2); 
     Afis.Extract(match); 

     // Compute similarity score 
     float score = Afis.Verify(probe, match);
