We have seen in the previous tutorial if two images are completely equal (same size, same channels, and same pixels values). But what if they’re not equal?The subtraction method doesn’t work anymore, as we can’t subtract pixels from images that have different sizes, we would get an error. In this article you will learn how […]
We’re going to learn in this tutorial how to track an object using the Feature matching method, and then finding the Homography. This detection method works only to track two identical objects, so for example if we want to find the cover of a book among many other books, if we want to compare two […]
In this tutorial we will talk about Feature Matching with OpenCV. In my example I used the same book cover but in different lighting conditions, position and perspective. For a normal comparison they could be different but two simple steps we can compare the main characteristics: Orb detector method Passing the image to the ORB […]
