OpenCV #005 Averaging and Gaussian filter

Digital Image Processing using OpenCV (Python & C++) Highlights: In this post, we will learn how to apply and use an Averaging and a Gaussian filter. We will also explain the main differences between these filters and how they affect the output image. What does make a good filter? This is a million dollar question. Tutorial Overview: Averaging filter Gaussian filter 1. Averaging filter What does make a good filter? So, let’s start with a…

OpenCV #004 Common Types of Noise

Digital Image Processing using OpenCV (Python & C++) Highlights: We will give an overview of the most common types of noise that is present in images. We will show how we can generate these types of noise and add them to clean images. Then, we will show how we can filter these images using a simple median filter. In this post, we will assume that we “know” how the noise looks like in our experiments…
