Come, let’s learn about image resizing with OpenCV. To resize an image, scale it along each axis (height and width), considering the specified scale factors or just set the desired height and ...
Reading and Writing Videos using OpenCV
Reading and writing videos in OpenCV is very similar to reading and writing images. A video is nothing but a series of images that are often referred to as frames. So, all you need to do is loop over ...
Read, Display and Write an Image using OpenCV
Reading, displaying, and writing images are basic to image processing and computer vision. Even when cropping, resizing, rotating, or applying different filters to process images, you’ll need to ...
Deep Learning with OpenCV DNN Mopencvodule: A Definitive Guide
The field of computer vision has existed since the late 1960s. Image classification and object detection are some of the oldest problems in computer vision that researchers have tried to solve for ...
Contour Detection using OpenCV (Python/C++)
Using contour detection, we can detect the borders of objects, and localize them easily in an image. It is often the first step for many interesting applications, such as image-foreground extraction, ...
Simple Background Estimation in Videos using OpenCV (C++/Python)
In many computer vision applications, the processing power at your disposal is low. In such cases, we have to use simple, yet effective techniques. In this post, we will cover one such technique ...
