c++ - Algorithms for eye gaze (eye-direction) in OPENCV -

-

i need implement algorithm eye gaze know direction of eye using opencv ,

i have been struggling 1 month using viola-jones algorithm training classifiers provided opencv

in first step based research starting facedetection.cpp xml's face , eye , can detect faces , eye < 1m haven't found method know eye direction

now after research , i've found algorithms eye-gaze don't wich 1 chooose in term of simplicity (because i'm newbie) , efficiency :

distance-threshold algorithm

mean-shift algorithm

edge detetction ==> hough transformation

the longest line scanning occluded circular edge

matching “one-circle” , "two-circle" algorithm

neural network based approaches

principal component analysis (pca).

starburst algorithm

kalman filter velocity

threshold eye movement identification

active appearence model (aam)

ccl : connected component labeling algorithm

cca : colonial competitive algorithm

blob detection

lucas kanade

so algorithm recommended me , , if there algorithm algorithms haven't mentionned , need comparaison between algorithms must experienced in field nb : i'm using ubuntu 14.04 , developping c++

any appreciated , :)

yii2 - Yii 2 Running a Cron in the basic template -

-
i have seen instructions on running cron in advanced template, cant figure out how on basic template. have following controller in basic controllers folder. <?php namespace app\controllers; use yii\console\controller; /** * cron controller */ class croncontroller extends controller { public function actionindex() { echo "cron service runnning"; } public function actionmail($to) { echo "sending mail " . $to; } } i have navigated root of application , tried these comands yii cron php yii cron im getting unknown comand "cron" i know old question failed find actual answer this. if @ code yii exec file you'll notice requires /common/config/aliases.php file console/config/main.php. can naturally change these or copy on these advanced template. hope solves problem wanting same thing.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

-
i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
