I am writing an iOS app that will do real-time face-detection using iPhone's Front camera.
In it, I need to check whether the lighting is proper or not. Like checking for "low light condition" or is left half light is more than right half light or vice versa.
I am checking both OpenCV on iOS and the iOS default face-detction using CIDetector
for one week but I am unable to find the solution.
Any Ideas or samples will be helpful.
In the same project iam using CIFaceFeature+FaceRotation to detect the face rotation angle its returning -1 to +1 values, but i need to show the values in 0 to 180 degrees (like user face is tilted 30 degrees)
Thanks.
