Swift - 如何检测一只眼睛眨眼

Question

我使用 CoreImage 来检测眨眼，它工作正常，除非我尝试只检测一只眼睛。关于如何使用 CoreImage 检测眼神接触调情的任何想法？

if let faceImage = CIImage(image: target) {  
    let accuracy = [CIDetectorAccuracy: CIDetectorAccuracyHigh]
    let faceDetector = CIDetector(ofType: CIDetectorTypeFace, context: nil, options: accuracy)
    let faces = faceDetector?.features(in: faceImage, options: [CIDetectorSmile:true, CIDetectorEyeBlink: true])

     if !faces!.isEmpty {
         for face in faces as! [CIFaceFeature] {
             let leftEyeClosed = face.leftEyeClosed
             let rightEyeClosed = face.rightEyeClosed
             let blinking = face.rightEyeClosed && face.leftEyeClosed
             let isSmiling = face.hasSmile

             print("isSmiling \(isSmiling)")
             print("blinking \(blinking)")
             print("rightEyeClosed \(rightEyeClosed)")
             print("leftEyeClosed \(leftEyeClosed)\n\n")
         }
     } else {
         print("No faces found")
     }
}

UPDATE 属性 hasLeftEyePosition 和 hasRightEyePosition 始终为真。

双眼紧闭

isSmiling false
blinking true
rightEyeClosed true
leftEyeClosed true

双眼睁开

isSmiling false
blinking false
rightEyeClosed false
leftEyeClosed false

左眼闭上

isSmiling false
blinking false
rightEyeClosed false
leftEyeClosed false

右眼闭上

isSmiling false
blinking false
rightEyeClosed false
leftEyeClosed false

要启用或禁用检测器的面部跟踪，我必须设置 CIDetectorTracking 变量。它可以很好地捕捉眨眼，但由于实时视频的性能较慢，我决定使用 ARKit 来实现它。

let accuracy = [CIDetectorAccuracy: CIDetectorAccuracyHigh, CIDetectorTracking: true] as [String : Any]
