### Initialize AfisEngine

Source: https://en.wikibooks.org/wiki/SourceAFIS/Tutorial

Create a static instance of the AfisEngine to ensure efficient access throughout the application.

```csharp
static AfisEngine Afis = new AfisEngine();
```

--------------------------------

### Import SourceAFIS Namespace

Source: https://en.wikibooks.org/wiki/SourceAFIS/Tutorial

Add the necessary namespace directive to your source file to access SourceAFIS classes.

```csharp
using SourceAFIS.Simple;
```

--------------------------------

### Create Fingerprint Objects

Source: https://en.wikibooks.org/wiki/SourceAFIS/Tutorial

Initialize Fingerprint objects using different image formats such as WPF BitmapSource, WinForms Bitmap, or raw grayscale data.

```csharp
// using .NET 3.0 (WPF) bitmap
Fingerprint fp1 = new Fingerprint();
fp1.AsBitmapSource = new BitmapImage(new Uri(pathToImage, UriKind.RelativeOrAbsolute));

// using .NET 2.0 (WinForms) bitmap
Fingerprint fp2 = new Fingerprint();
fp2.AsBitmap = new Bitmap(Bitmap.FromFile(pathToImage));

// using raw grayscale image (see API docs for format description)
Fingerprint fp3 = new Fingerprint();
fp3.Image = myRawImage;
```

--------------------------------

### Perform One-to-Many Fingerprint Identification

Source: https://en.wikibooks.org/wiki/SourceAFIS/Tutorial

Use AfisEngine.Identify to search a collection of candidates for a matching fingerprint. This method is optimized for performance compared to manual LINQ queries.

```csharp
Person matchingCandidate = Afis.Identify(probePerson, allCandidates).FirstOrDefault();
bool match = (matchingCandidate != null);
```

```csharp
Person matchingCandidate = (from candidate in allCandidates
              let score = Afis.Verify(probePerson, candidate)
              where score >= Afis.Threshold
              orderby score descending
              select candidate).FirstOrDefault();
bool match = (matchingCandidate != null);
```

--------------------------------

### Verify Fingerprint Match

Source: https://en.wikibooks.org/wiki/SourceAFIS/Tutorial

Compare two Person objects to determine if they match by checking the similarity score returned by the engine.

```csharp
float score = Afis.Verify(person1, person2);
bool match = (score > 0);
```

--------------------------------

### Extract Fingerprint Template

Source: https://en.wikibooks.org/wiki/SourceAFIS/Tutorial

Perform the extraction process to generate a template from the fingerprint image, which is required for matching.

```csharp
Afis.Extract(person);
```

--------------------------------

### Wrap Fingerprint in Person Object

Source: https://en.wikibooks.org/wiki/SourceAFIS/Tutorial

Add a fingerprint to a Person object to prepare it for template extraction.

```csharp
Person person = new Person();
person.Fingerprints.Add(fp);
```
