我想使用此代码通过CIFaceDetector检测图像中的人脸。由于图像方向无法检测图像中的人脸
let Orientation: Int!
switch ((info[UIImagePickerControllerOriginalImage] as? UIImage)?.imageOrientation)! {
case UIImageOrientation.up:
Orientation = 1
case UIImageOrientation.down:
Orientation = 3
case UIImageOrientation.left:
Orientation = 8
case UIImageOrientation.right:
Orientation = 6
case UIImageOrientation.upMirrored:
Orientation = 2
case UIImageOrientation.downMirrored:
Orientation = 4
case UIImageOrientation.leftMirrored:
Orientation = 5
case UIImageOrientation.rightMirrored:
Orientation = 7
}
let options = [CIDetectorAccuracy: CIDetectorAccuracyHigh, CIDetectorImageOrientation: Orientation] as [String : Any]
let faceDetector = CIDetector(ofType: CIDetectorTypeFace, context: nil, options: options)
let faces = faceDetector?.features(in: personciImage)
但是,这只适用于风景权。我不知道为什么它不适用于所有其他方向。我的意思是应该设置正确的方向。我也将一个UIImage投射到CIImage上。
guard let personciImage = CIImage(image: (info[UIImagePickerControllerOriginalImage] as? UIImage)!) else {
return
}
问题在那里?
