OpenCV: Sobel Filter

In this tutorial we will see two OpenCV functions which we can use to apply the Sobel and Scharr filters to an image to detect edges.

In this tutorial we will get familiar with three OpenCV functions which generate the kernel matrices, used by filters like Sobel and Scharr.

In this tutorial we will see how to create linear filters and how to apply them to an image in order to remove any noise and blur it.

In this tutorial I will introduce you to some important core guidelines on how to develop high-quality classes using OOP main principles.

In this tutorial we will see yet another operation on images – thresholding and how to apply it using ready OpenCV functions.

In this tutorial we will see yet another functionality of OpenCV, related to colors – colormaps, which we can use to colorize images.
