Using CIFaceFeature detection, can I determine the Confidence of the Face detected in an Image -


i'm starting take @ cidetector detect faces in image wondering whether has had luck determining confidence level detector has when detected face.

i know can set detector threshold choosing different detector accuracies, there way tell how detected feature has surpassed requested accuracy?

cicontext *context = [cicontext contextwithoptions:nil]; nsdictionary *opts = @{ cidetectoraccuracy : cidetectoraccuracyhigh }; cidetector *detector = [cidetector detectoroftype:cidetectortypeface                                       context:context                                       options:opts];

essentially, if have image has 2 faces in - how can determine of 2 more face assuming both detected using cidirectoraccuracyhigh option?

thanks

the lower index in nsarray of cifeatures more face according documentation in coreimage

/** returns array of cifeature instances in given image.  array sorted confidence, highest confidence first. */ - (nsarray *)featuresinimage:(ciimage *)image __osx_available_starting(__mac_10_7, __iphone_5_0);

javascript - RequestAnimationFrame not working when exiting fullscreen switching space on Safari -

request animation frame stops working when exiting fullscreen clicking on original space's safari window. fine if fullscreen mode canceled escape key or calling cancelfullscreen(). steps reproduce: open https://dl.dropboxusercontent.com/u/769042/prezi/safari-fullscreen.html click "draw raf", kittie appears click "fullscreen", go fullscreen click "draw raf", kittie appears go space original safari was, showing "click exit fullscreen mode", click anywhere, out fullscreen click "draw raf", nothing happens what handling click calling: window.requestanimationframe(draw); which draws on canvas context: function draw() { ctx.drawimage(img, math.random()*500|0, math.random()*400|0, 100, 100); } i checked .hidden , .visibilitystate, updated correctly. tested on osx 10.9.3, safari 7.0.4 (9537.76.4). has workaround/solution other switching old settimeout? this sounds webkit bug 88940 : using reque
