[OpenCV] video reading and some simple image processing, opencv reading1. Preface As a computer image processing tool, openCV began to show some irreplaceable advantages due to free disclosure, copyright, and so on (it has been shown for a long time ). Well, I have been working with MATLAB in my graduate school. I always feel like debugging, verification, or MATL

mechanism. Whenever someone copies the information header of a Mat object, it increases the number of references to the matrix, whereas when a header is released, the count is reduced by one; When the count is zero, the matrix is cleared. But at some point you still want to copy the matrix itself (not just information headers and matrix pointers), you can use the function clone () or copyTo () . 1 Mat F = a.clone (); 2 Mat G; 3 A.copyto (G);changing F or G now does not affect the matrix that t

OpenCV learning notes (1) -- OpenCV Development Environment Configuration Abstract: Due to the recent popularity of AR (Augmented Reality), various AR-based applications and games are gradually oriented to the public. The two most important technologies in AR are tracking, recognition, and enhanced rendering, tracking and recognition is implemented through the open-source computer vision library

First of all, thank De Lihui Teacher Translation finishing of the "Opencv-python Chinese course", this document is really good, for OpenCV beginners, help is very large, can let beginners quick start. Recommend two OPENCV learning sites: (1) http://docs.opencv.org/2.4/index.html This site can query the use of

Learning the learning notes series of OpenCV-Environment configuration 2, opencv learning notes To learn OpenCV well, you must first know how to configure the environment. Take your own configuration environment as an example. The steps are as follows. Step 1 download and decompress the OpenCV source code Although many

This is very helpful for noise removal. In fact, the removal of high-frequency components in the image (e.g. noise, boundary). So the border will be blurred a bit. (Of course
