OpenCV Python Tutorial For Beginners 5 - Draw geometric shapes on images using Python OpenCV

description
In this video on OpenCV Python Tutorial For Beginners, I am going to show How to Draw geometric shapes on images using Python OpenCV. You will learn these functions : cv.line(), cv.circle() , cv.rectangle(), cv.ellipse(), cv.putText() etc. cv2.line() : Used to draw line on an image. cv2.rectangle() : Used to draw rectangle on an image. cv2.circle() : Used to draw circle on an image. cv2.putText() : Used to write text on image. Gist of code I used in this video (OpenCV & Python – Drawing shapes and text on images (cv2)) - http://www.codebind.com/python/opencv-python-tutorial-beginners-draw-geometric-shapes-images-using-python-opencv/ pip is a package management system used to install and manage software packages written in Python. OpenCV is an image processing library created by Intel and later supported by Willow Garage and now maintained by Itseez. opencv is available on Mac, Windows, Linux. Works in C, C++, and Python. it is Open Source and free. opencv is easy to use and install. Starting with an overview of what the course will be covering, we move on to discussing morphological operations and practically learn how they work on images. We will then learn contrast enhancement using equalization and contrast limiting. Finally we will learn 3 methods to subtract the background from the video and implement them using OpenCV. At the end of this course, you will have a firm grasp of Computer Vision techniques using OpenCV libraries. This course will be your gateway to the world of data science. Feel the real power of Python and programming! The course offers you a unique approach of learning how to code by solving real world problems. #ProgrammingKnowledge #ComputerVision #OpenCV ★★★Top Online Courses From ProgrammingKnowledge ★★★ Python Programming Course ➡️ http://bit.ly/2vsuMaS ⚫️ http://bit.ly/2GOaeQB Java Programming Course ➡️ http://bit.ly/2GEfQMf ⚫️ http://bit.ly/2Vvjy4a Bash Shell Scripting Course ➡️ http://bit.ly/2DBVF0C ⚫️ http://bit.ly/2UM06vF Linux Command Line Tutorials ➡️ http://bit.ly/2IXuil0 ⚫️ http://bit.ly/2IXukt8 C Programming Course ➡️ http://bit.ly/2GQCiD1 ⚫️ http://bit.ly/2ZGN6ej C++ Programming Course ➡️ http://bit.ly/2V4oEVJ ⚫️ http://bit.ly/2XMvqMs PHP Programming Course ➡️ http://bit.ly/2XP71WH ⚫️ http://bit.ly/2vs3od6 Android Development Course ➡️ http://bit.ly/2UHih5H ⚫️ http://bit.ly/2IMhVci C# Programming Course ➡️ http://bit.ly/2Vr7HEl ⚫️ http://bit.ly/2W6RXTU JavaFx Programming Course ➡️ http://bit.ly/2XMvZWA ⚫️ http://bit.ly/2V2CoAi NodeJs Programming Course ➡️ http://bit.ly/2GPg7gA ⚫️ http://bit.ly/2GQYTQ2 Jenkins Course For Developers and DevOps ➡️ http://bit.ly/2Wd4l4W ⚫️ http://bit.ly/2J1B1ug Scala Programming Tutorial Course ➡️ http://bit.ly/2PysyA4 ⚫️ http://bit.ly/2PCaVj2 Bootstrap Responsive Web Design Tutorial ➡️ http://bit.ly/2DFQ2yC ⚫️ http://bit.ly/2VoJWwH MongoDB Tutorial Course ➡️ http://bit.ly/2LaCJfP ⚫️ http://bit.ly/2WaI7Ap QT C++ GUI Tutorial For Beginners ➡️ http://bit.ly/2vwqHSZ ★★★ Online Courses to learn ★★★ Get 2 FREE Months of Unlimited Classes from skillshare - https://skillshare.eqcm.net/r1KEj Data Science - http://bit.ly/2lD9h5L | http://bit.ly/2lI8wIl Machine Learning - http://bit.ly/2WGGQpb | http://bit.ly/2GghLXX Artificial Intelligence - http://bit.ly/2lYqaYx | http://bit.ly/2NmaPya MERN Stack E-Degree Program - http://bit.ly/2kx2NFe | http://bit.ly/2lWj4no DevOps E-degree - http://bit.ly/2k1PwUQ | http://bit.ly/2k8Ypfy Data Analytics with R - http://bit.ly/2lBKqz8 | http://bit.ly/2lAjos3 AWS Certification Training - http://bit.ly/2kmLtTu | http://bit.ly/2lAkQL1 Projects in Java - http://bit.ly/2kzn25d | http://bit.ly/2lBMffs Machine Learning With TensorFlow - http://bit.ly/2m1z3AF | http://bit.ly/2lBMhnA Angular 8 - Complete Essential Guide - http://bit.ly/2lYvYRP Kotlin Android Development Masterclass - http://bit.ly/2GcblsI Learn iOS Programming Building Advance Projects - http://bit.ly/2kyX7ue ★★★ Follow ★★★ My Website - http://www.codebind.com DISCLAIMER: This video and description contains affiliate links, which means that if you click on one of the product links, I’ll receive a small commission.
