iPhone app for detecting faces from a live camera feed using Swift and iOS 13 API's.

facedetection's Issues

Crashes on launch (iOS 9.3)

Swift error:

Video started.
Features: []
fatal error: unexpectedly found nil while unwrapping an Optional value

Should be easy to fix.

Add support for any screen size

Easiest way to accomplish this is by adding a launch screen if we're only targeting iOS 8+.

Very slow on older devices

The frame rate is very low, around 0.5 fps on iPhone 4S and the app receives memory warning in about 8 seconds. Hope that helps! 👍

Update to Swift 2

Have gone through the basic migration process to support Swift 2, but haven't fully embraced the improvements. Code should be refactored to use newer syntax such as guard, defer, where needed, and use struct and protocols in place of classes where possible.

Continuous Integration

We should set up a Travis build server to compile this repo and check for build errors - and, in future, to run our tests.

http://next.travis-ci.com indicates that iOS 9 and Swift 2 are supported.

I haven't done this before, but there's a great summary of setting up a build server in Objective-C here and one for setting one up with Swift 1.2 here. With both of those, it shouldn't be hard to figure out Swift 2.

Working but live capture is pixelated.

Thanks for your work. Updated to Swift 3 / iOS 10 and all is working.

The pixelation is coming from FaceObscurationFilter but is this all the app is meant to do? Anything you point the camera at is pixelated so where does the Face Detector come into play?

Update README

It's outdated, and needs rewriting - preferably with more of an explanation as to what's going on with regards to the camera input, CIDetector, etc.

Recording ?

What's the best way we can go about recording a video from this? Including the layers that are being tracked onto the face?

It doesn't build with latest swift changes

hello,
il pulled it and tried to launch it but It doesn't build with latest swift changes.
I tried the migration tool they provided but it still doen't work.
can i have help please ?

Pixellate faces

Instead of covering with black.

How can I test the face detection program on Xcode?

Hi , I am a new xcode developer, now I am trying to build a face counting program on ios.
I saw your code on github and tried to run it , but the error appeared "Can not record", I guess that is because the program can not get access to the camera in the iphone simulator, is there any solution to this ?

Use new Vision API's

Benchmark detection performance

We don't need to be super thorough about this, as we can assume Apple have done testing of their implementations themselves. However, we need to find out which API performs best in general out of the following:

• CIDetector
• AVCaptureMetadataOutput as mentioned by @D-Link13 in #3
• Any others? We could possibly check OpenCV if neither of the above are satisfactory, but that's a big dependency to include if the SDK already provides a good enough solution.

It's also possible both of these implementations are backed by the same algorithm, so performance might be identical. It would be interesting to find out!

unrecognized selector sent to class

I tried to run the example on my iOS7.1 iPhone5 and got the following error on start:

Video started.

Ios 10 crash

hi with ios 10 it crash at start

2016-11-17 17:43:11.092619 FaceDetection[4651:1307406] [access] This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSCameraUsageDescription key with a string value explaining to the user how the app uses this data.

but NSCameraUsageDescription was added

Update to Xcode 8

Xcode 8 has new compiler settings we should enable, and uses automatic code signing.

Ask for camera permissions nicely

At the moment, first launch demands camera access with no context. This is just a demo app, but it should still ask nicely - that means including something to display if the user declines access, too. Right now that would result in a black screen.

• Improve UI for asking for camera permission
• Add interface for when the user denies camera permission

logo for FaceDetection

Hello,
Good Day, i make a logo icon for your project.I make a 3 logo for you.Which logo do you like? If you want to use this logo in your project, then comment below, I will give you the source file. And if you want a change, then tell me I will change.It's totally free for open source project.

Update to Swift 3

Swift 3 is publicly released now. We should update to the latest Swift syntax.
