使用openImaj API库进行面对齐

Question

我想使用openImaj对齐我在这里使用的几个面。我想阅读一张jpg脸部照片，对齐它，最后在对齐后保存为jpg格式。这里是我卡住的地方。见下面

 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); 

    } 
} 

我需要什么代码才能将face_test.jpg对齐到face_aligned.jpg？

对准器与面部检测器结合使用，所以您需要使用检测器来查找面部并将其传递给对准器。不同的校准器与不同的检测器实现相关联，因为它们需要不同的信息来执行对齐;例如仿射对准器需要FKEFaceDetector找到的面部关键点。基本代码如下所示：

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"));
