What is filtering and how to use it?

Image filtering is always a powerful tool to use in your Computer Vision applications. It allows you to apply many exciting effects on your photos, such as image correction, noise reduction, embossing, and many more. Image filtering is actually a huge subpart of an image processing area. In this section, we will discuss the concepts of image filtering and talk about a basic operation—convolution, which is widely used in all Computer Vision applications.
