This module is based on the great Visualization Toolkit library VTK and nicely prepares the users for the upcoming Open.CV 3. In this guide, I will show you how to install Open.CV with a lot of the features it provides.Here are some of the things that are going to be enabled when you are finished following through with this installation tutorial viz module 3.D visualizationQt version of the High.GUI module Better 2.D window interface with zoom, image saving capabilities, etcOpen.GL support.

L, Open. GL and Qt are all detected correctly.Make sure you scroll up and check that the modules that are going to be built are these core flann imgproc highgui features.If anything is wrong, go back, correct the errors by maybe installing extra packages and then run cmake again.Now, you are ready to compile and install Open.CV 2. 4. 9. sudo make install.Now you have to configure Open.CV. First, open the opencv.Add the following line at the end of the fileit may be an empty file, that is ok and then save it.Run the following code to configure the library.Now you have to open another file.Add these two lines at the end of the file and save it.PKGCONFIGPATHPKGCONFIGPATH usrlocallibpkgconfig.PKGCONFIGPATH. Finally, close the console and open a new one, restart the computer or logout and then login again.Open. CV will not work correctly until you do this.Now you have Open.CV 2. 4. 9 installed in your computer with 3.D visualization, Python, Java, TBB, Open.GL, video, and Qt support.Check out the cool Qt interface which provides image viewing capabilities with zoom, as well as the ability to save the current image with just one click.If you zoom in enough, you can see the RGB or intensity values for each pixel.Now lets build some samples included in Open.CV. cd opencv 2. These examples use the old C interface.Open. CVhaarcascadeshaarcascadefrontalfacealt.Open. CVhaarcascadeshaarcascadefrontalfacealt.Open. CVhaarcascadeshaarcascadeeye.The following examples use the new C interface.Now lets run some Python code.Now you can build a Java sample using ant for example.Make sure that you change homesamontab with your actual home directory.Docv.

Dirhomesamontabopencv 2.Now lets read a video and use Open.GL with Qt through this great sample that detects the features from the video, then estimates the 3.D location of the structure using POSIT, and finally uses Open.GL to draw in 3. D great sample Javier.Qtsample. Open. GLQtBinding.And finally, lets build a sample using the 3.D visualization module viz.As you can see, now you can use Open.CV with C, C, Python, and Java.The Qt enhanced 2.D interface is enabled, 3.D data can be displayed using Open.GL directly, or using the new viz module.Multi threading functionality is enabled using TBB.Also, video support is enabled as well.If you correctly finished this tutorial, you are now ready to do some nice computer vision work.
