First, we import the cv2 module and the time module. The time module is to create a delay to slow down the video to make it viewable by a human. Next, we create a variable, cap. We assign this variable to, cv2.VideoCapture('yoga.mp4). This allows us to open up the video in the...
In this article, we show how to display an OpenCV image in Python with the matplotlib module. OpenCV is a powerful, versatile module that allows us to do many computer vision tasks, including working with images. Opening an image in OpenCV is as simple as using the cv2.imread() ...
We will start by importing the cv2 module, which will expose to us the function we need to draw text on an image. 1 importcv2 After that, we will load an image from the file system with a call to theimreadfunction. As input, we pass the path to the image we want to use. When ...
pip install opencv-python Next, create a main.py file and add the following code to it: import cv2 # Open the video file video_input = cv2.VideoCapture('dog.mp4') # Get video properties including width, height, and frames per second (FPS) fps = video_input.get(cv2.CAP_PROP_FPS) fr...
Python extract a specific frame from video Here, we can seehow to extract a specific frame from videoin python. In this example, I have imported a module callednumpy as npandcv2, and then read the file by specifying the path. To give the value of the framecap.set(1, 16)is used. ...
In this code snippet, we import thecv2module and read the image file “example.jpg”. Thecv2.resizefunction is used to change the size of the image. Similar to the previous method, you provide the new dimensions as a tuple. After resizing, the image is saved with the name “example_res...
Instead, we only want to normalize a portion of the image. We can define that portion in the mask so that normalization will only be performed on the masked portion. For example, let’s reduce the glare present in an image using the normalize() function. See the code below. import cv2...
