Building OpenCV from the source code. Java OpenCV project in Eclipse.3. Examples and code based on real-life implementation of OpenCV to help the reader understand the importance of this technology. To use OpenCV functionality you need to add OpenCV library initialization code before using any OpenCV specic code, for example, to the static section of Activity class. Im currently using python 2.7, C and OpenCV 3.0, and all I can find is how to do it in OpenCV 2.4, but the problem is that it differs a lot from 3.0 where the ml::TrainData somehow is used instead. I dont understand how it works, and theres no example code! You should be able to compile and run simple Hello World! example.Write simple code to get OpenCV version: Without any settings to project properties, the result should be " OpenCV Version: 3.0.0." in Debug and Release mode. 3 Dropping old skin OpenCV 1.x: C API Why 3.0?

Its quite a burden!5 OpenCV v3.0: moving towards community-driven project OpenCV 3.0 alpha right after CVPR Will not be compatible with OpenCV 2.x (users code may why there is no openCL (ocl) in opencv 3.
0 beta? I heard that the new opencv transparently uses opencl, but when I am testing this on a windows running onRegarding speed, I would ensure below. In cvconfig.h in build directory, check if OpenCL flag is ON or OFF. In code, ocl::setUseOpenCL(true). OPENCVEXTRAMODULESPATH: This is used when you need some extra contributed module set the path for the source code of the extra modules here (for example, C:/opencv contrib-master/modules). OpenCV Community. Supported Platforms. Library Design. Example: Gesture Recognition. Research code (slow, unstable, independent/incompatible data types for every library/toolbox). Very expensive commercial toolkits (like Halcon, MATLABSimulink OpenCV includes an example ([opencvsourcecode]/samples/cpp/textdetection.cpp) that detects and draws text regions in an input image. KAZE AKAZE features. Several 2D features have been proposed in the computer vision literature. Unfortunately many examples Ive tried, dont work, because cv2.cv seems to be missing in OpenCV3.
