![]() In this method, we first import the cv2 module from the OpenCV library. Gray_image = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)Ĭv2.imwrite('gray_image.jpg', gray_image) Here's an example program that uses OpenCV to convert an image to grayscale: import cv2 OpenCV is a powerful open-source computer vision library that provides various functionalities for image processing, including converting images to grayscale. Finally, we save the grayscale image using the save() method, passing the filename for the grayscale image as an argument. Next, we use the convert() method on the image object and pass 'L' as an argument, which stands for luminance, to convert the image to grayscale. Then, we open the image using the Image.open() method, passing the filename of the image as an argument. In this method, we first import the Image class from the Pillow library. Here's an example program that uses the Pillow library to convert an image to grayscale: from PIL import Image The Pillow is a popular Python imaging library that provides various functionalities for image processing, including converting images to grayscale. In this blog post, we will explore different methods to convert an image to grayscale in Python, along with their program code, output, and explanations. Grayscale images are commonly used in various image-processing applications, such as image recognition, computer vision, and medical imaging. In grayscale images, the intensity of each pixel is represented by a single value ranging from 0 (black) to 255 (white). Grayscale images, also known as black and white images, are images that consist of shades of gray instead of color.
