• Different methods to find a form of rectangle Center and rotation in vision assistant

  Hi This is my first shot at the machine vision and Vision Assistant tool. I am trying to find a rectangle shape in an image and determine its Center and rotation around the Center. I started with this image:

  

  and I increased saturation and contrast to make a clearer target area:

  

  I am interested in the main red rectangle turned about 5 degrees to the right. For me, it seems that there is enough contrast edges, but quickly, I tried some of the edge (including the rake) detection and pattern matching algorithms and I don't get any useful results. Maybe it's the white lines don't interfere. I tried to extract just the plan of the red color but as white also contains red these lines always appear.

  I'm hoping to get some ideas for different approaches get precisely the Center and the rotation of this part, as well as the guidance you need to succeed. Thanks for the tips!

  I would try to extract the rectangle using color thresholding.  Analysis of particles of use on the rectangular blob and you should be able to get a rotation value.

• Since Apple ridiculously decided to abandon the center of games tab of my friends in the game does not load automatically and I have to go to GC and click the circle of friends so he could load, MORE I wonder constantly if I want to use my game stored loc

  Since Apple decided to abandon the center of games tab of my friends in the game does not load automatically and I have to go to GC icon and tap the circle of friends so he could load several times, MORE we continue to request if I want to use my game stored locally or my stored GC game. I refuse to install iOS 10, because it means of course I won't be able to manually load the tab my friends and my losing my game completely. How can I fix it? Remove the Center game is the worst thing that Apple could have done, in my humble OPINION.

  You will not lose your game entirely. I have several games of game Center, and they work fine. And I understand the developer of a game that this game center continues to store the backup of your game.

  It's just that now friending is handled via the interface of the game. The only options that you have in iOS10 is to go to the settings panel in / log out of game center or remove all friends. And none of the games I play has updated so I can see how their friending works with iOS10.

  Beyond providing the basic interface, Apple seems to have turned all aspects of the social game on the games themselves.

  If you want to make Apple know how you feel, you can leave your comments via this form

• How can I determine the order of firstname and lastname?

  I get the name of the contact with the following code.

  BlackBerryContact contact = ...
  String[] name = contact.getStringArray(Contact.NAME, 0);
  String firstName = name[Contact.NAME_GIVEN];
  String lastName = name[Contact.NAME_FAMILY];
  

  But I can't determine the order - "full name, first name" or "first name, last name.
  With my Bold 9700, it can be configured in the Options > language and text input > name display, but I couldn't find a way to get the setting from java code.

  Please help me.

  There is no API for this setting. If you see as important, you could offer it to your own parameters, otherwise just go with the standard.
