C:/path/to/opencv/) for the next step. However, because I am new to opencv and multithreading, my implementation has caused my image processing functions to produce erroneous results. OpenCV Python Examples (Camera Capture) For the C++ implementation see this and this post. A web pod. The blog is full of OpenCV source code, tutorials, tips, tricks, and from basics to advanced streaming and video processing. OpenCV’s claim to fame is it’s ability to effortlessly work with video feed, either live or recorded.Each frame of the video is considered as a single image,and then processed on.There are many tutorials available on the ‘net on how to go about doing this, but a mojority of them are in C, not C++. Also, when a connected camera is multi-head (for example, a stereo camera or a Kinect device), the correct way of retrieving data from it is to call VideoCapture::grab() first and then call VideoCapture::retrieve() one or more times with different values of the channel parameter.
