OpenCV configuration with Visual Studio

Today i'll show you the how can you manually configure OpenCV 2.4.11 with Visual Studio 2013.

Open the visual studio File > New > New Project > Installed > Template > Visual C++ > CLR then click on CLR Console Application and named the project as TestOpenCV then hit OK.

Go to Link and download opencv 2.4.11, you can choose any latest version of opencv, process will be same as following.
Create a new folder in Drive C named as cv2411 and extract in it. Your directory should be like following image.

First of all you need to set System Environment Variable in windows. Open Control panel > System and Security > System > Advance system settings > Advanced click on Environment Variables button. Select Path from System variables then click Edit and paste bin path as following then click OK OK and OK :).

• C:\cv2411\opencv\build\x86\vc12\bin

Go back to Visual Studio, right click on project and select properties. I'm building opencv for x86 platform in visual studio but you can also use x64. For this you just need to change path as x64. In properties panel go to Configuration Properties > VC++ Directories > Include Directories then click drop down edit button and add following path.

• C:\cv2411\opencv\build\include

In Libraries Directories add following path

• C:\cv2411\opencv\build\x86\vc12\lib

Go to C/C++ > Additional Include Directories and paste following directory

• C:\cv2411\opencv\build\include

Go to Linker > Additional Library Directories and paste following directory

• C:\cv2411\opencv\build\x86\vc12\lib

Go to Linker > Input >Additional Dependencies and paste following libraries name 

• opencv_calib3d2411d.lib
• opencv_contrib2411d.lib
• opencv_core2411d.lib
• opencv_features2d2411d.lib
• opencv_flann2411d.lib
• opencv_gpu2411d.lib
• opencv_highgui2411d.lib
• opencv_imgproc2411d.lib
• opencv_legacy2411d.lib
• opencv_ml2411d.lib
• opencv_nonfree2411d.lib
• opencv_objdetect2411d.lib
• opencv_photo2411d.lib
• opencv_stitching2411d.lib
• opencv_superres2411d.lib
• opencv_ts2411d.lib
• opencv_video2411d.lib
• opencv_videostab2411d.lib

If you want to configure opencv in Release mode the simply remove d from above libraries names.
Then click on Apply button then OK. Your opencv has been configured. Now let's run some lines of code to test OpenCV, just copy following code and paste in TestOpenCV.cpp file.

• #include "stdafx.h"
  #include <iostream>
  #include <opencv/cv.h>
  #include <opencv/highgui.h>
  #include <opencv2/core/core.hpp>
  #include <opencv2/opencv.hpp>
  #include <opencv2/imgproc/imgproc.hpp>
  #include <opencv2/highgui/highgui.hpp>
  
  using namespace std;
  using namespace cv;
  
  int main()
  {
    Mat image;
    image = cv::imread("C:\\test.png");
    namedWindow("Display window", 1);
    imshow("Display window", image);
    waitKey(0);
    return 0;
  }

Build the project and run.
If you are facing dll missing errors then simply go to following path and copy all dll files and paste them with project .exe file. You can find project exe file in Project directory. it will be in Debug or Release folder.

• C:\cv2411\opencv\build\x86\vc12\bin

If you have any issue or suggestion please comment below.

How to configure opencv in Eclipse IDE

Firstly, I'm assuming that you have installed OpenCV on Ubuntu. If not, then follow the link. Secondly You need to install Eclipse + JDK7. Following command will install eclipse for c++ developer with JDK7. Just Run following command.

• sudo apt-get install eclipse eclipse-cdt g++

Open Eclipse and right click or Go to File > new project > C/C++ > C++ Project > Next

Name the project as TestOpenCV and select Hello World C++ Project then click next. Write Author name whatever you want then click next next and finish.

Before to run project expand src directory and add following lines of code in TestOpenCV.cpp

• #include "stdfix.h"#include <iostream>
  #include <opencv/cv.h>#include <opencv/highgui.h>
  #include <opencv2/core.hpp>
  #include <opencv2/opencv.hpp>
  #include <opencv2/imgproc/imgproc.hpp>
  #include <opencv2/highgui/highgui.hpp>
  
  using namespace std;
  using namespace cv;
  
  int main()
  {
          Mat image;
          image  = cv::imread("/home/test.png");
          namedWindow("Display window", 1);
          imshow("Display window",image);
          waitKey(0);
          return 0;
  }

Now Right on project > properties > C/C++ Build > Settings > Cross G++ Compiler > Includes

Run following commands to get includes paths

• pkg-config --cflags opencv

Copy all include paths and add into include paths (-I) tab like following

Run following command in terminal to get all libraries paths and lib files

• pkg-config --libs opencv

Now Click on Cross G++ Linker > Liberalities
and add lib path in Library search path (-L) tab and all OpenCV libs in Libraries(-I) tab

• Path: /usr/local/lib
• Libs: opencv_calib3d opencv_contrib opencv_core opencv_features2d opencv_flann opencv_gpu opencv_highgui opencv_imgproc opencv_legacy opencv_ml opencv_nonfree opencv_objdetect opencv_ocl opencv_photo opencv_stitching opencv_superres opencv_ts opencv_video opencv_videostab

It may be different if you installed different version.

Click OK and build the project the project and run.

How to install Opencv on Ubuntu Desktop/Ubuntu Server

To install OpenCV on your system run the following commands in terminal. You should have Ubuntu/Server 12 or 14 LTS to install it.

• sudo apt-get update
• sudo apt-get upgrade
• sudo apt-get install libtiff5-dev
• sudo apt-get install build-essential libgtk2.0-dev libjpeg-dev libtiff5-dev libjasper-dev libopenexr-dev cmake python-dev python-numpy python-tk libtbb-dev libeigen3-dev yasm libfaac-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev libx264-dev libqt4-dev libqt4-opengl-dev sphinx-common texlive-latex-extra libv4l-dev libdc1394-22-dev libavcodec-dev libavformat-dev libswscale-dev default-jdk ant libvtk5-qt4-dev

You can change OpenCV version in following command, just go to link and change the version in following OpenCV URL, like I'm using 2.4.11 here.

• cd~
  wget http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.4.11/opencv-2.4.11.zip
  unzip opencv-2.4.11.zip
  cd opencv-2.4.11
• mkdir build
  cd build
  cmake -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON -D WITH_VTK=ON ..

Now, you are ready to compile and install OpenCV 2.4.11:

• make
• sudo make install

Now, you have to configure OpenCV first. Open the opencv.conf file with the following command if you are using Ubuntu desktop

• sudo gedit /etc/ld.so.conf.d/opencv.conf

If you are using Ubuntu Server then open file with following command

• sudo nano /etc/ld.so.conf.d/opencv.conf

Add following lines at the end of the file (it may be an empty file, that is ok) and then save it:

• /usr/local/lib

To save file use CTRL+X then press y then hit enter.

Run the following command to configure the library

• sudo ldconfig

Now you have to open another file:

• if you are using Ubuntu Desktop then use this command
• sudo gedit /etc/bash.bashrc
• if you are using Ubuntu Server then use this command
• sudo nano /etc/bash.bashrc

Add these two lines at the end of the file and save it:

• PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
  export PKG_CONFIG_PATH

Finally, close the terminal and open a new one, restart the computer or logout and then login again. OpenCV will not work correctly until you do this.

To see where opencv installed use following command

• pkg-config --cflags opencv

To see lib files directory use following command

• pkg-config --libs opencv

Let run simple c++ code with opencv code using g++ compiler. Create new file and named it as test.cpp and add following code in it

• #include "stdfix.h"#include <iostream>
  #include <opencv/cv.h>#include <opencv/highgui.h>
  #include <opencv2/core.hpp>
  #include <opencv2/opencv.hpp>
  #include <opencv2/imgproc/imgproc.hpp>
  #include <opencv2/highgui/highgui.hpp>
  
  using namespace std;
  using namespace cv;
  
  int main()
  {
          Mat image;
          image  = cv::imread("/home/test.png");
          namedWindow("Display window", 1);
          imshow("Display window",image);
          waitKey(0);
          return 0;
  }

Save the file, open terminal cd to directory where you save test.cpp file and write following command in terminal

• g++ `pkg-config --cflags opencv` text.cpp `pkg-config --libs opencv` -o test

Your file is build with opencv, just write following command to run test file

• ./test

Thanks :)

Windows 10 Features VS Windows 8.1

Windows 10 VS Windows 8.1

Using Windows 10 almost from day of released. I have discovered little changes and feature
that Microsoft hasn't yet discussed . Let's dive straight in with favorite secret features of
Windows 10.

"Home" tab in Explorer now

In the last few version of windows, opening My Computer or a new Explorer window
would show you your computer's various storage locations and shortcuts to default folders
like Documents and My Pictures. In Windows 10, you now end up in a new view called
Home, which shows Favorites, Frequent Folders, and Recent Files. Take loo at the 
screen shot below and you'll see what i mean.

Windows 10 This PC Home

Favorites seems to be where Documents or My Pictures should appear. I don't know the
 math behind the Frequent Folders, but it looks like just tracks which folders I have 
opened the most times. Recent Files is like the Recent Places feature That premiered in
Windows Vista, but just for files.

I assume that folders can be added to the Favorites section, but I've not yet worked
out how to do it. (To be honest, the more advances features of Explorer, lie Libraries, are
still pretty hard to penetrate).

"This PC" is still available from the left-hand menu if you want to manage your various storage locations/default folders. I like the new Home tab a lot.

Windows 10 Home Tab

  
Recycle Bin on the task bar

Rather than having to take around Explorer or minimize everything and find the Recycle
Bin icon on Dextop, in Windows 10 you can now add the Recycle Bin to both
the task bar and the Start menu. Yes, that is the sound of many brains exploding as they catastrophically realize the enormity of this change.

Recycle Bin at Task Bar and Start Menu

Windows 10 Start menu is re-sizable

This feature is much odd one. You can make the Windows 10 Start menu as tall or as wide as you
like. If you want to have a Start menu that takes up the entire left side of your screen, or a narrow
strip across the task bar, the that's show now possible. The task bar itself is also re sizable, which means you can do weird stuff this:

Re sizable Windows 10

Cortana is coming to Windows 10

Search with Cortana also coming in Windows 10 new features. There is a lot of references to Cortana in windows 10 Technical Preview, there is even a

Windows.Cortana .dll       just sitting in System32 directory.

You also get lot of Cortana-related hits if you search "Cortana "  within the Registry Editor.

I'm hopefully see Cortana in the next beta of Windows 10. None of this is say that
Cortana is definitely coming to Windows 10.

Windows 10 Cortana

Toasts Notification in Windows 10

There are some pretty toasts/notifications that pop up in the top right corner of the screen.
These notification appear to replace the speech bubble s that used to pop out of the system tray
(this task bar , unless you are one of those heathens who has moved the task bar to a non-standard location).You can see Example Image below, but there are similar toasts for successful uploads to
Drop-box and similar activities.

It seems that notification or toasts are configures though the same interface that Metro notification used in Windows 8/8.1 i.e PC settings (see below).

Windows 10 Toast Notification

The new Notification Tray might only be coming soon in Metro interface.

Why did Microsoft Skip Windows 9 [Rumor]

Few day back when Microsoft announced the windows 10 as their next version of Windows was the most unexpected surprised at San Francisco event.
However why did Microsoft skip windows 9 and jump directly to Windows 10.

One of the developer from Microsoft named cranbourne stated on Reddit that
Microsoft dev here, the internal rumours are that early testing revealed just how many third party products that had code of the form

if(version.StartsWith("windows9"))
{
      /*95 and 98*/
}
else {

and that this was the pragmatic solution to avoid that.

And if Microsoft named Windows 10 as Windows 9, then all classic apps with
above code will deal it as windows 95 or Windows 98. So that's why Microsoft skip Windows 9.

Unity From Scratch

Unity Interface

Unity Interface depends on 5 parts .Following interface can be adjusted in your way , just drag and drop set it as you like...

1. Tool bar
2. Scene
3. Inspector
4. Project
5. Hierarchy

• Hierarchy

Hierarchy contains some GameObject of your current Scene. Some of these are direct instance of asets files, like Prefabs and 3D Models.

Parenting

Unity uses a concept called Parenting, to make any GameObject the child of another. Just Drag the desired child into desired Parent in the Hierarchy. Inherited child will move and rotate according to it's Parent.

Store Procedure in SQL Server

Store Procedure is subroutine available to Application  that access Relational Database System.

Few important things are to be noted:

• Not like Views in Access SP (Store Procedure) are pre-compiled in database.
• Keyword is PROC or PROCEDURE.
• Increase the Usability in Query Optimization.
• Store in Database.
• Wipe out from memory after their execution.

How to code?

Open SQL-Server, Create new Database named as EmployeeDB and Table named as Employee

Add following fields names in table

Make sure ID set as auto increment and Primary Key 

Expand Tables => right-click on dbo.Employee => Edit Top 200 Rows and Add dummy data like following

To make sure data is added, click on New Query (placed at right corner), and  paste following code and Click

SELECT * FROM [EmployeeDB].[dbo].[Employee];

How to Create Store Procedure ?

·          Using same query we create store procedure .

·          Paste/Replace following code and click Execute.

CREATE PROC SPAllEmployee

AS

SELECT * FROM [EmployeeDB].[dbo].[Employee];

It create store procedure named as SPAllEmployee.

You can also see that Store Procedure file is created in Database => EmployeeDB => Programmability => Store Srocedures.

Now, 

How To Call Store?

Click New Query Paste following Code and Execute.

Exec SPAllEmployee

How to Alter Store Procedure ?

·         Using same Store Procedure SPAllEmployee we alter this SP(Store Procedure). Now we are going to change the query . Click New Query Paste Following Code and Click Execute.

ALTER PROC SPAllEmployee

AS

SELECT * FROM [EmployeeDB].[dbo].[Employee] AS E

WHERE E.City='Lahore';

Click New Query Paste Following Code and Execute

            
            Exec SPAllEmployee

See query result is changed now.

How to Drop Store Procedure? 

Simple click on New Query and Execute Following code.

DROP PROCEDURE SPALLEmployee;

How to Create Store Procedure with Parameter?

      Again create new Store Procedure named as SPnewEmployee in New Query  and Execute following lines of code.

CREATE PROC SPnewEmployee

@param varchar(50)

AS

SELECT * FROM [EmployeeDB].[DBO].[Employee] AS E

WHERE E.[City]=@param;

EXEC SPnewEmployee 'Lahore'

If you want pass two or more parameter just separated with comma.

Now create new Store Procedure in New Query and Execute following lines of code it.

CREATE PROC SPnewEmployeeTwo

@city varchar(50),

@departmentName varchar(50)

AS

SELECT * FROM [EmployeeDB].[DBO].[Employee] AS E

WHERE E.[City]= @city AND E.DepartmentName=@departmentName;

And now click New Query paste following code and then click on Execute.

EXEC SPnewEmployeeTwo @city='Lahore', @departmentName='English';
