The mouse pointer is a key component in a Graphical User Interface (GUI). Without it, you can’t really think of interacting with a GUI. So, let’s dive in and get introduced
Edge detection is an image-processing technique that is used to identify the boundaries (edges) of objects or regions within an image. Edges are among the most important features associated with
Have you ever tried to blur or sharpen an image in Photoshop, or with the help of a mobile application? If yes, then you have already used convolution kernels. Here,
Annotating images and videos serves more than one purpose, and OpenCV makes the process straightforward and easy. See how you can use it: Once you learn to annotate images, annotating
Image editing has become more and more popular these days as mobile phones have this built-in capability that lets you crop, rotate, and do more with your images. In this
Come, see for yourself, how Cropping an Image using OpenCV works. First, why do we need to crop? Cropping is done to remove all unwanted objects or areas from an
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
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.
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 first read
Most of the Machine Learning and Deep Learning problems that you solve are conceptualized from the Generative and Discriminative Models. In Machine Learning, one can clearly distinguish between the two
