OpenCV 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.

The difference between installing a python package from source and through pip are given in the following table:. Note: All the points in the table are written with respect to OpenCV but they can also be generalized for other libraries and packages.

In this article, we will give priority to the installation of OpenCV from source so that developers can modify the installation with respect to their task. We will be explaining the installation from source for Windows Click on the link to redirect to the latest release web page of OpenCV. Once the download is complete, unzip the files at your desired location. If you do not have git installed in your system then you can click on the above link and clone it from the website.

Make sure that you have cloned the repository next to the unzipped OpenCV folder. Note: There are other versions of OpenCV as well. If you are interested to download them then you can scroll down to find out what you are looking for. After cloning, downloading and unzipping the archive, it will be something like the screenshot shown below:.

The opencv In the final step of this tutorial, we will use one of the modules of OpenCV to run a sample code which will verify the installation. Visual Studio is a powerful IDE which helps developers to write and debug the large amount of code smartly as well as quickly as possible. In this tutorial, we are not going to write code but we will use Visual Studio to demonstrate the compilation of OpenCV in Release mode.

Click on the setup file downloaded to start the installation of Visual Studio Installer. The installer will be downloaded and finally a window will pop up on the screen which will want you to select the working environments to be installed along with the installation of Visual Studio.

You can select multiple workloads as per your requirements to be installed into your system. We are going to select two workloads for the illustration of OpenCV installation which are as follows:. Note: However, you can change the location, if there is not enough space left in the system for the installation of workloads. After selecting the workloads, click on the install button to get the installation job done. This will take around 10 minutes to 1 hour depending upon the internet speed.

Follow the simple steps to install the CMake. We are not going to discuss the installation of OpenCV using command line but if you want to follow the command line instructions then I would like to recommend you to check the next section which is OpenCV installation in Ubuntu. The commands are similar for both Windows and Ubuntu, if command line tool is used for installation. In the source code field, you have to browse to the folder where we have unzipped the OpenCV files.

In the second text box, you have to provide a path where the newly build binaries along with Visual Studio Project file will be saved. Note: It is not necessary that the newly build binaries folder should exist in advance.Library of programming functions mainly aimed at real-time vision.
