android - CameraSource(vision api) not detecting when phone is in landscape mode -


i have created app track eyes using vision api , working fine when phone portrait mode when tilde phone landscape position app pauses camera , went onmissing() method.

please give me suggestion app can work in both layouts or can sense eyes phone rotations (0,90,180,270)

code:

private void createcameraresources() {     context context = getapplicationcontext();      // create , setup face detector     mfacedetector = new facedetector.builder(context)             .setprominentfaceonly(true)             .settrackingenabled(true)              .setclassificationtype(facedetector.all_classifications)             .setmode(facedetector.fast_mode)              .build();      mfacedetector.setprocessor(new largestfacefocusingprocessor(mfacedetector, new facetracker()));      if (!mfacedetector.isoperational()) {         log.w(tag, "createcameraresources: detector not operational");     } else {         log.d(tag, "createcameraresources: detector operational");     }     mcamerasource = new camerasource.builder(this, mfacedetector)             .setrequestedpreviewsize(640, 480)             .setfacing(camerasource.camera_facing_front)             .setrequestedfps(30f)             .build(); }    public class facetracker extends tracker<face> {  private static final float prob_threshold = 0.7f; private static final string tag = facetracker.class.getsimplename(); private boolean leftclosed; private boolean rightclosed;  @override public void onupdate(detector.detections<face> detections, face face) {     if (leftclosed && face.getislefteyeopenprobability() > prob_threshold) {         leftclosed = false;     } else if (!leftclosed &&  face.getislefteyeopenprobability() < prob_threshold){         leftclosed = true;     }     if (rightclosed && face.getisrighteyeopenprobability() > prob_threshold) {         rightclosed = false;     } else if (!rightclosed && face.getisrighteyeopenprobability() < prob_threshold) {         rightclosed = true;     }      if (leftclosed && !rightclosed) {         eventbus.getdefault().post(new lefteyeclosedevent());     } else if (rightclosed && !leftclosed) {         eventbus.getdefault().post(new righteyeclosedevent());     } else if (!leftclosed && !rightclosed) {         eventbus.getdefault().post(new neutralfaceevent());     } }

manifest file:

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.android.eyetoggle">  <uses-permission android:name="android.permission.camera" /> <application     android:allowbackup="true"     android:icon="@mipmap/ic_launcher"     android:label="@string/app_name"     android:supportsrtl="true"     android:theme="@style/apptheme">     <activity         android:name=".mainactivity">         <intent-filter>             <action android:name="android.intent.action.main" />              <category android:name="android.intent.category.launcher" />         </intent-filter>     </activity> </application>  </manifest>

corresponding xml layout:

<?xml version="1.0" encoding="utf-8"?> <android.support.percent.percentframelayout       xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="20dp" tools:context="com.android.eyetoggle.mainactivity">  <linearlayout     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_gravity="center_horizontal"     android:orientation="horizontal">      <android.support.v7.widget.switchcompat         android:id="@+id/switchbutton"         android:layout_width="wrap_content"         android:layout_height="wrap_content" />      <textview         android:id="@+id/emoticon"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="@string/emoji_neutral" /> </linearlayout>   <view     android:id="@+id/light"     android:layout_gravity="center"     android:background="@color/green"     app:layout_aspectratio="100%"     app:layout_widthpercent="75%" />  </android.support.percent.percentframelayout>

you need check orientation change , like,

private void startifready() throws ioexception {     if (mstartrequested && msurfaceavailable) {         mcamerasource.start(msurfaceview.getholder());         if (moverlay != null) {             size size = mcamerasource.getpreviewsize();             int min = math.min(size.getwidth(), size.getheight());             int max = math.max(size.getwidth(), size.getheight());             if (isportraitmode()) {                 // swap width , height sizes when in portrait, since rotated                 // 90 degrees                 moverlay.setcamerainfo(min, max, mcamerasource.getcamerafacing());             } else {                 moverlay.setcamerainfo(max, min, mcamerasource.getcamerafacing());             }             moverlay.clear();         }         mstartrequested = false;     } }  @override protected void onlayout(boolean changed, int left, int top, int right, int bottom) {     int width = 320;     int height = 240;     if (mcamerasource != null) {         size size = mcamerasource.getpreviewsize();         if (size != null) {             width = size.getwidth();             height = size.getheight();         }     }      // swap width , height sizes when in portrait, since rotated 90 degrees     if (isportraitmode()) {         int tmp = width;         width = height;         height = tmp;     }  private boolean isportraitmode() {     int orientation = mcontext.getresources().getconfiguration().orientation;     if (orientation == configuration.orientation_landscape) {         return false;     }     if (orientation == configuration.orientation_portrait) {         return true;     }      log.d(tag, "isportraitmode returning false default");     return false; }

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
