Step-by-step guide to capture live stream with camera.In addition, this tutorial will cover saving a frame as an image as well as saving it as a video in your machine. We are going to use the built-in VideoCapture and VideoWriter classes that comes with OpenCV.
By reading this piece, you will learn to capture a video using the built-in webcam in your laptop. If you are using a personal computer, make sure that you have it connected with an external webcam.
In addition, this tutorial will cover saving a frame as an image as well as saving it as a video in your machine. We are going to use the built-in
VideoWriter classes that comes with OpenCV.
There are 3 sections in this piece:
Let’s proceed to the next section and start installing the necessary modules
It is highly recommended to create a virtual environment before you continue with the installation. Once you are done with it, run the following command
pip install opencv-python
You can check if you have installed it correctly via
pip show opencv-python
Let’s move to the next section for the implementation.
Learn Free how to create a virtual pen and eraser with python and OpenCV with source code and complete guide. This entire application is built fundamentally on contour detection. It can be thought of as something like closed color curves on compromises that have the same color or intensity, it's like a blob. In this project we use color masking to get the binary mask of our target color pen, then we use the counter detection to find the location of this pen and the contour to find it.
This video explains how to find and draw image contours using Python's Opencv. It will also explain the concept of image segmentation in opencv, a technique
In this Python tutorial, you'll learn how to extract images/frames from videos. OpenCV comes with many powerful video editing functions. In current scenario, techniques such as image scanning, face recognition can be accomplished using OpenCV. Image Analysis is a very common field in the area of Computer Vision. It is the extraction of meaningful information from videos or images. OpenCv library can be used to perform multiple operations on videos.
In this article, we will learn how to perform image stitching using Python and OpenCV
OpenCV Python in Python will explain all the basics of OpenCV. It also explains how to create a face recognition system and a motion detector.
