- (void)setBetterFaceImage:(UIImage *)image{ [self setBetterFaceImage:image]; // Cycle Call? }

if I don't want to hack setImage, this is a Cycle Call.

Added a way to turn ON and OFF Logs, just define BF_DEBUG on the prefix file or add it on the compile macro to turn it ON.

In the demo project I added it on the prefix file.

Moved the CIDetector as a singleton as there was some overhead in the creation of new CIDetectors which Apple's Documentation recommends against. https://developer.apple.com/library/ios/documentation/CoreImage/Reference/CIDetector_Ref/Reference/Reference.html

This should improve the performance of UIImageViews inside scroll views.

Core Image Contexts/Detectors should be initted (yes that's made up) as sparsely as possible. The reason being is each time you init one you're using GPU compute and memory. This competes with a things like UIScrollViews which are very GPU intensive.

CIDetector is still very resource hungry and I've only tested this code on an iPad Air for performance where its usable, around 40fps rather than 60fps.

First of all, The open source is so cool. Thanks.

In TableView. When I download image from server Use SDWebImage.
The memory is so high. and how can I reduce the memory ? Can you give me some opinions?

At UIImage+BetterFace.h，

- (UIImage *)betterFaceImageForSize:(CGSize)size accuracy:(BFAccuracy)accurary;

how to use size parameter？ use image size? or UIImageView size？

GitHub changed the way Markdown headings are parsed, so this change fixes it.

Full code:

Repro steps:

1. App should let user to choose between photo library and camera as a source of the new image.
2. Select a photo with two faces that works 100% with BetterFace library from the Photo Library.
3. After seeing that BF works fine with the photo from the Photo Library, now select a new photo using the Camera as a source.
4. ImageView still has the old photo from the Photo Library.

Any ideas? I've been debugging this for an hour already.
