The newest features of OpenCV3

3.0 will be another revolutionary version of OPENCV, what changes will it bring?

• The OpenCV 2 Classic C + + and Python programming interface styles are largely preserved. The Python interface is greatly enhanced, and the Python 3.x support is added. In general, the previous version of the program as long as a few changes, you can use OpenCV 3. In addition, the Java interface has been improved and MATLAB support has been added.

• Schema tuning. Image, video codec separated from the Highgui module, composed of Imgcodecs and Videoio. The original OpenCL module OCL is in fact integrated with other modules, and the Cuda acceleration module GPU is decomposed into several modules that begin with Cuda. In addition, in addition to the official support of the OPENCV code, there are some self-contributing content, unstable content, or the copyright of the disputed content, are placed in the new warehouse Opencv_contrib.

• More new algorithms. The new version includes new algorithms such as TLD, fisheye lens model, and a number of high-level packages that can be used directly, such as automotive testing.

• Introduce T-api to make opencl acceleration easier. You can now refer to the example of T-api in OpenCV source code. You can see that the OpenCL acceleration is turned on and off, and only one statement is required. This is why the OCL module disappears.

• More instruction set optimizations. In addition to the optimizations previously made for Intel CPUs, the OpenCV 3 also accommodates the support of the ARM platform neon instruction set. With Intel's help, the OpenCV 3 uses IPP by default on the x86 and x64 platforms, and this acceleration of leverage is not much to say!

So what is the most concerned about stability now? OpenCV 3.0 Beta passed most of the tests, only a small part of the 32-bit windows that did not pass, for general use is not too much of a problem.
