Recently, the computer re-installed system, the first thing to reload OpenCV.This is the latest version of the direct install, published in 2014-4-25 OpenCV2.4.9 version number, download link:Http://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.4.9/opencv-2.4.9.exe/download. In fact the installation process is almost identical to the 2.4.4 process. This is a mistake to record the process. 2.4.4

Matlab and C ++ mixed programming (dependent on OpenCV), and Matlab OpenCVMatlab and C ++ hybrid programming is actually to compile C ++ code into executable files and function interfaces that Matlab supports calling through Matlab's Mex tool. In this way, you can use the functions that have been compiled in Matlab, even though this function is written in C ++. Communication without borders is achieved, and there is no one who is unified, and there is

OPENCV Automatic memory managementThe current version of OPENCV is automatically processing all of its own memory, although that is not very rigorous. OpenCV introduced a new C + + interface in version 2.0, using automatic memory management to give a new way to solve the problem. With this approach, developers don't have to tangle with managing memory, and your c

[OpenCV] expands the image boundary and opencv expands the image boundary. In image processing, some attribute values at the current pixel position are often calculated using the adjacent pixels of the current pixel. This will lead to cross-border access to the border pixel. Generally, there are two ways to solve this problem: this article mainly introduces how to use O
