使用openImaj API庫進行面對齊

Question

我想使用openImaj對齊我在這裏使用的幾個面。我想閱讀一張jpg臉部照片，對齊它，最後在對齊後保存爲jpg格式。這裏是我卡住的地方。見下面

 public class FaceImageAlignment { 

    /** 
    * @param args the command line arguments 
    */ 
    public static void main(String[] args) throws IOException { 
     // TODO code application logic here 

     BufferedImage img = null; 
     img = ImageIO.read(new File("D:/face_test.jpg")); 

     //How to align face image using openImaj 
     //This is where I am stuck on doing face alignment. I tried doing the following 
     AffineAligner imgAlign = new AffineAligner(); 
     //but I could not figure out how to do face alignment with it 



     BufferedImage imgAligned = new BufferedImage(//I will need to put aligned Image here as a BufferedImage); 
     File f = new File("D:\\face_aligned.jpg"); 
     ImageIO.write(imgAligned, "JPEG", f); 

    } 
} 

我需要什麼代碼才能將face_test.jpg對齊到face_aligned.jpg？

對準器與面部檢測器結合使用，所以您需要使用檢測器來查找面部並將其傳遞給對準器。不同的校準器與不同的檢測器實現相關聯，因爲它們需要不同的信息來執行對齊;例如仿射對準器需要FKEFaceDetector找到的面部關鍵點。基本代碼如下所示：

FImage img = ImageUtilities.readF(new File("...")); 
FKEFaceDetector detector = new FKEFaceDetector(); 
FaceAligner<KEDetectedFace> aligner = new AffineAligner(); 
KEDetectedFace face = detector.detectFaces(img).get(0); 
FImage alignedFace = aligner.align(face); 
ImageUtilities.write(alignedFace, new File("aligned.jpg"));
