CLFaceDetectionImagePicker (NOT OPENCV!!!)

CLFaceDetectionImagePicker is a clean and so-easy-to-use ImagePicker meant to do live face detection. It will draw a square if any face is detected in the camera as below and take photo automatically if the face detection is passed.

Installation

Drag the CLFaceDetectionImagePickerSourceCode folder into your project.

Demo Usage

Please download all of the files in the repo and run it directly to have a look.

Use CLFaceDetectionImagePicker wisely! Lights in front of the camera will affect the accuracy of face detection.

Initialize

Using CLFaceDetectionImagePicker in your app will usually look as simple as this :

_imagePickerViewController = [CLFaceDetectionImagePickerViewController new];
_imagePickerViewController.delegate = self;

//Show the ImagePicker
[self presentViewController:self.imagePickerViewController animated:YES completion:nil];

Delegate

After the imagePicker take photo or dismiss without detecting any face, it will fire CLFaceDetectionImagePickerDidDismiss delegate function as below which you need to apply

//After getting data callback
-(void)CLFaceDetectionImagePickerDidDismiss:(NSData *)data blnSuccess:(BOOL)blnSuccess
{
    self.statusInfo.text = (blnSuccess)?@"Success":@"Failed";

    if(data){
        self.imageView.image = [UIImage imageWithData:data];
        self.imageView.hidden = NO;
    }else{
        self.imageView.hidden = YES;
    }
}

Customisation

**Please be aware customisation delegate function is optional, if u do not apply it, it will just fire the default value.

Using CLFaceDetectionImagePickerDelegate to customise the behaviour

Following customisation key is allowed

-CLTotalDetectCountDownSecond; //Total length of waiting period for face detection - Default: 10

-CLFaceDetectionSquareImageName; //Image name for the face detection square image - Default: CameraSquare

-CLFaceDetectionTimes; //Continually detecting face times, this will be helpful to make sure the people are not shaking his head by purpose - Default: 5

-CLCameraPosition; //Choose which camera you want to use, CLCaptureDevicePositionBack or CLCaptureDevicePositionFront -Default: CLCaptureDevicePositionFront

You need to fire below delegate function to apply your customisation

// Optional!!! Set The Face Detection Behavior Attributes
-(NSDictionary *)faceDetectionBehaviorAttributes
{
    return @{
        CLFaceDetectionTimes : @10,                 //Total times for capture clear detected face images to prevent user shake their heads in purpose
        CLFaceDetectionSquareImageName : @"CameraSqaure", //Different FaceDetection Square Image. try to use "squarePNG" for different image
        CLTotalDetectCountDownSecond : @12,        //Total waiting time, after this value, the picker will auto closed no matter it get face detected or not.
        CLCameraPosition : [NSNumber numberWithInteger:CLCaptureDevicePositionFront] //Which camera try to use, Front or back.  CLCaptureDevicePositionBack or CLCaptureDevicePositionFront
    };
}
