Description

UIImage+FaceDetection is an Objective-C category for UIImage. It gives UIImage the ability to return a 'CIFaceFeature' for each face found within the image.

Use

1. Add the CoreImage framework to your project
2. Add the files 'UIImage+FaceDetection.h' & 'UIImage+FaceDetection.m' to your project
3. Import the header using #import "UIImage+FaceDetection.h"
4. Call the - (NSArray *)facesWithAccuracy :(NSString *)detectorAccuracy method in the following way:

UIImage *myImage = [UIImage imageNamed:@"exampleImage.png"];
NSArray *faces = [myImage facesWithAccuracy:CIDetectorAccuracyHigh];

Other Functions

Return the largest face from the image - (CIFaceFeature *)largestFaceWithAccuracy :(NSString *)detectorAccuracy

Return an image cropped around the largest face - (UIImage *)croppedAroundLargestFaceWithAccuracy :(NSString *)detectorAccuracy

Future

1. Better handling when an invalid or nil 'CIDetectorAccuracy' is passed in.
2. Return nil or error when no faces are found.
3. Additional methods for returning smallest face.
4. Additional methods for returning centre-most, left-most & right-most faces.
5. Add podspec.
