基于OpenCV的边缘检测算法在仪表识别中的应用与改进_岳利军
Various algorithms are available for edge detection and are applied in the OpenCV library. One such technique is the Sobel Edge Detection algorithm. This tutorial will demonstrate the Sobel algorithm using OpenCV in Python. Edge Detection Using theSobel()Function Using OpenCV in Python ...
Update 2018-11-30:I added a CMake compile flag to enable nonfree algorithms (OPENCV_ENABLE_NONFREE=ON). This is required for OpenCV 4 if you want access to patented algorithms for educational purposes. Note:For the above CMake command, I spent considerable time creating, testing, and refac...

When used in a real-world installation, it’s highly recommended to test the algorithms and filters in the actual environment because things like lights, background color or object choice have significant effects on the result. This also includes shadows from daylight, people standing around, and...
如果获得特征和它的描述后,您可以在所有图像中找到相同的功能并将它们对齐,拼接它们或做你想要的操作。 So in this module, we are looking to different algorithms in OpenCV to find features, describe them, match them etc. 所以模块中,我们正在寻找不同的算法去发现这些特征,描述它们,匹配它们等。
