Combine two overlapping frame by simple correlation This tutorial use matchTemplate openv function to combine two images into one. Today morning, I read this post combine two overlapping video frames on StackOverflow. The problem is to merge 2 images together or two video streams. I am thinking about the most simple not so much dummy solution. I find a really simple solution that can be extended to a more complex one. First of all, I took 2 images from the phone like on the picture (color images). The program selects Rectangles region from both source images and resize end extract this ROI rectangles. The idea is to find the "best" overlapping Rect regions by normalized correlation and combine these images on a place with maximal correspondence. I know well solution by SIFT and SURF, but it is a little bit laborious than this. It is not the best solution but one of the simplest. If your cameras are fixed in stable position between

The blog is full of OpenCV source code, tutorials, tips, tricks, and from basics to advanced streaming and video processing. The code examples are from C++. Most of the tutorials are dedicated to basics C++ OpenCV image processing, people detection from LBP haar cascades to modern deep learning. The tutorials are as well dealing with GStreamer OpenCV integration to be able to stream OpenCV output as a video stream to the web.
