Image analysis is a very common field in computer vision. It is the extraction of meaningful information from videos or images. The OpenCv library can be used to perform several operations on video.
import cv2 import os
VideoCapture (File_path): Read the video (.mp4 format)
read (): Read data depending upon the type of object that calls
imwrite (filename, img [, params]): Saves an image to a specified file.
Below is the implementation:
# Import all required libraries
# Read the video at the specified path
"C: Users Admin PycharmProjects project_1 openCV.mp4"
# create a folder named data
# if not created, then issue an error
’ Error: Creating directory of data’
# read from frame
< code class = "undefined spaces">
# if there is still video, continue creating images
’. / data / frame’
# write extracted images
cv2.imwrite (name, frame )
# increment counter to make it
# show how many frames were created
# Free all space and windows as soon as done
All extracted images will be saved to folder named "data" on the system.
