Opencv experiences (1) The second chapter of learning opencv mainly introduces some common and interesting functions and data types, so that students at the beginning are more interested in image processing, although I do not understand the internal experiment of the function and the meaning of some defined constants, I am still very happy after

OpenCV 2.4.9 Learning Note (3)--OPENCV automatically allocates memory for an output array (matrix)

the array frame because the video Analysis Module Videocapture component has been able to obtain the resolution and bit depth information of the USB camera. While the Cvtcolor method automatically allocates memory for the edges array, the data information for the edges array is the same as the input array, and Cv_bgr2gray determines the color space type of the output image. In the above loop, edges's memory is only allocated once, and if the resolution of the input image changes, the memory is

Basic Learning notes opencv (22): A connection domain processing function in the Learning opencv book

     Preface In the process of image processing, we often encounter such a part of the image. The whole part of the image can be seen at a glance, but it is broken due to various internal gaps, in this way, the computer "eye" is considered disconnected. In order to adapt the image to the human eye, these gaps and disconnected ports need to be connected, this requires the connection domain processing technology in computer graphics. This article provides a simple connection domain processing func
