Introduction: Opencv and Python Installation for Windows / MacOpenCV is an open source computer vision library which is very popular for performing basic image processing tasks such as blurring, image blending, enhancing image as well as video quality, thresholding etc. In addition to image processing, it provides various pre-trained deep learning models which can be directly used to solve simple tasks at hand. The programmers have to download and load the model using OpenCV instructions in order to do the task of inference on their own dataset.Firstly, you need to install OpenCV library in your system prior to using it for your own dataset. At this stage, there can be two pathways of installing OpenCV in your system namely – (a) Using pip (b) Source Installation. pip is the package manager which is used to install the packages written in python. The difference between installing a python package from source and through pip are given in the table:Step 1: Download OpenCVStep 2: Download OpenCV-contribAs you can see in the image above, Click on Sources button to download OpenCV – 4.1.0 archive files into your system. Once the download is complete, unzip the files at your desired location. For illustration purpose, I am going to create a folder named as ‘opencv’ in my Desktop and I will unzip the downloaded archive inside the same folder.In order to download OpenCV_contrib you must open the command line tool and clone the repository by executing the following command: for windows: click on Clone /
