OpenCV is an open-source Python library, which used to understand the content of the digital image. The CV is the abbreviation form of computer vision. It extracts the description from the real-time image or digital image, which may be an object, a text description, and so on. Show We can perform many tasks using the OpenCV library such as face detection, face recognition, blob detection, edge-detection, image filter, template matching, and etc. To work with the OpenCV, we need to install it in our Python environment. Installation of OpenCVHere, we install the OpenCV using the following ways.
Using pip commandOpen a command prompt and type the following command. Or, we can install it without extra module by the following command. Now, we will verify the proper installation of OpenCV. Import the cv2 module and print its version. If it has properly installed, then it will show its version. Using AnacondaAnaconda is a software package of Python. Anaconda with Jupyter is a the best way to work with the OpenCV. First, we need to install the Anaconda graphics installer from its official site. Now, choose a suitable bit installer. Once download is completed. Open the Anaconda prompt and type the following command. Then, hit the enter button and it will download all rated OpenCV configuration. Now, we are ready to work with the OpenCV. You can learn complete OpenCV through our OpenCV tutorial (https://www.javatpoint.com/opencv). GoalsIn this tutorial
Below steps are tested in a Windows 7-64 bit machine with Visual Studio 2010 and Visual Studio 2012. The screenshots shows VS2012. Installing OpenCV from prebuilt binaries
If the results are printed out without any errors, congratulations !!! You have installed OpenCV-Python successfully. Building OpenCV from source
Additional ResourcesExercisesIf you have a windows machine, compile the OpenCV from source. Do all kinds of hacks. If you meet any problem, visit OpenCV forum and explain your problem. How do you install OpenCV?Building OpenCV from source. Download and install Visual Studio and CMake. ... . Download and install necessary Python packages to their default locations. ... . Make sure Python and Numpy are working fine.. Download OpenCV source. ... . Extract it to a folder, opencv and create a new folder build in it.. How do I import an OpenCV module into Python?To use OpenCV, we need to install it.. Step 1 − Make sure Python and pip is preinstalled on your system. Type the following commands in command prompt to check is python and pip is installed on your system. To check Python. ... . Step 2 − Install OpenCV. OpenCV can be installed using pip.. What is the command to install pip?Ensure you can run pip from the command line
Run python get-pip.py . 2 This will install or upgrade pip. Additionally, it will install setuptools and wheel if they're not installed already. Be cautious if you're using a Python install that's managed by your operating system or another package manager.
What is cv2 package in Python?cv2 is the module import name for opencv-python, "Unofficial pre-built CPU-only OpenCV packages for Python". The traditional OpenCV has many complicated steps involving building the module from scratch, which is unnecessary. I would recommend remaining with the opencv-python library.
