1. IO operation of image Here we will introduce how to read images, how to display images and how to save images. 1.1 reading images API: cv.imread() Parameters: Image to readFlag of reading mode cv.IMREAD_COLOR: when loading an image in color mode, the transparency of any image will be ignored. This is the default parameter.cv.IMR ...

1, dlib library introduction and related installation 1.1 INTRODUCTION Dlib library is an open source library of machine learning, which contains many algorithms of machine learning. It is very convenient to use. It can directly include header files, and does not depend on other libraries (with its own image codec library source code). Dl ...

Background: judge whether there is a pig in the vehicle in the video returned by on-board monitoring Solution: do object recognition in the returned video. If there is a pig, frame it and give a representative value day1 2021-10-27 Imagine: object recognition and frame it in the figure 1. Align the sample In the beginning, there was no con ...

Computer vision expert Adrian roserock recently shared how to write a scanning program that can recognize QR code and bar code in real time with the help of OpenCV and Zbar. Finally, he deployed it on raspberry pie and successfully made a practical bar code & QR code scanning device. Recently, a friend asked me if there are any modul ...
