Check if the image is empty using Python - OpenCV Last Updated : 03 Jan, 2023 Comments Improve Suggest changes Like Article Like Report Prerequisite: Basics of OpenCV OpenCV (Open Source Computer Vision) is a computer vision library that contains various functions to perform operations on pictures or videos. It was originally developed by Intel but was later maintained by Willow Garage and is now maintained by Itseez. This library is cross-platform that it is available in multiple programming languages such as Python, C++, etc. In this article, we’ll try to check if the opened image is empty or not by using OpenCV (Open Source Computer Vision). To do this OpenCV libraries are required to install: pip install opencv-pythonTo achieve this objective we will use cv2.imread() method, If this method read the image then it returns the image coordinates matrix otherwise it will return None. Input Image: Gfg.png Example: In this example, we will read the image and check found or not. Python3 # Importing OpenCV library import cv2 # user define function # that return None or def check_empty_img(img): # Reading Image # You can give path to the # image as first argument image = cv2.imread(img) # Checking if the image is empty or not if image is None: result = "Image is empty!!" else: result = "Image is not empty!!" return result # driver node img = "Gfg.png" # Calling and printing # the function print(check_empty_img(img)) Output: Image is not empty!!Example 2: In this example, here the image is not found. Python3 # Importing OpenCV library import cv2 # user define function # that return None or def check_empty_img(url): # Reading Image # You can give path to the # image as first argument image = cv2.imread(url) # Checking if the image is empty or not if image is None: result = "Image is empty!!" else: result = "Image is not empty!!" return result # driver node img = "geek.png" # Calling and printing # the function print(check_empty_img(img)) Output: Image is empty!!

Not only supported by any system, such as Windows, Linux, Mac, etc. but also it can be run in any programming language like Python, C++, Java, etc. OpenCV also allows you to identify color in images.

OpenCV is an open source library used mainly for processing images and videos to identify shapes, objects, text etc. It is mostly used with python. In this article we are going to see how to detect shapes in image. For this we need cv2.findContours() function of OpenCV, and also we are going to use 3 min read Cropping Faces from Images using OpenCV - Python Opencv is a python library mainly used for image processing and computer vision. In this article first, we detect faces after that we crop the face from the image. Face detection is the branch of image processing that uses to detect faces. We will use a pre-trained Haar Cascade model to detect faces 3 min read Add image to a live camera feed using OpenCV-Python In this article, we are going to learn how to insert an image in your live camera feed using OpenCV in Python. Stepwise ImplementationStep 1: Importing the libraries CV reads and stores all the images as a NumPy array. We need the NumPy library to manipulate the image and as expected we need the cv2 4 min read Like
