Python opencv print image dimensions, shape to get the dimensions of the image

Python opencv print image dimensions, 0 of OpenCV and version 3. Using OpenCV (cv2) OpenCV is useful and fast computer vision library. Let’s get started. 7. When working with OpenCV Python, images are stored in numpy ndarray. 0. Nov 23, 2019 · In this tutorial we will learn how to obtain the dimensions (height and width) of an image read with OpenCV, using Python. The most common are PIL (Pillow) and OpenCV. 2 of Python. ( Examples will be shown in a Python terminal, since most of them are just single lines of code ) Apr 12, 2025 · Why Image Dimensions Matter Image dimensions define width and height in pixels. This tutorial was tested with version 4. Oct 23, 2012 · Image size (Python, OpenCV) Asked 13 years, 4 months ago Modified 4 years, 8 months ago Viewed 291k times Jul 23, 2025 · Finding the width and height of an image in Python means reading the image and determining its dimensions in pixels. An Image is a 2-D array of Pixels. Image in Pillow (PIL). They affect file size, quality, and display. Apr 29, 2025 · This article explains how to get the image size (width and height) in Python using OpenCV and Pillow (PIL). shape(). Dimensions of the image refer to the height, width, and number of channels of the image. Sep 30, 2013 · How to get the size of an image in cv2 wrapper in Python OpenCV (numpy). We are going to learn about how to fetch the size of the image using OpenCV Python with an example. In Image Processing applications, it is often necessary to know the size of an image that is loaded or transformed through various stages. Then, you can use index on the dimensions variable to ge Oct 20, 2022 · During image processing, it’s essential to know the size of the image with which we work, which is being transformed through various stages. For example an image might have a height of 135 pixels and a width of 600 pixels. Apr 12, 2025 · Why Image Dimensions Matter Image dimensions define width and height in pixels. Proper handling ensures optimal performance. To get the image shape or size, use ndarray. In Python, you can work with dimensions using several libraries.

A good knowledge of Numpy is required to write better optimized code with OpenCV. Is there a correct way to do that other than numpy. Let’s explore some common methods to find an image’s width and height. 1. How can I get it in these format dimensions: (width, height) list?. You can obtain the image size as a tuple using the shape attribute of ndarray in OpenCV and the size attribute of PIL. shape to get the dimensions of the image. 1 day ago · Access image properties Set a Region of Interest (ROI) Split and merge images Almost all the operations in this section are mainly related to Numpy rather than OpenCV. Oct 20, 2022 · Since Python is extensively used for real-life applications such as Web-Development, Machine Learning, Artificial Intelligence, Data Science, etc and it’s of no surprise that we can get the size (dimensions) of any image using Python OpenCV. When working with OpenCV, images are stored in NumPy ndarray (N-Dimensional array). It's important to note that the order of width and height differs between OpenCV and Pillow (PIL).
