Median filter is a filter of nonlinear class. This article is a practical guide for understanding and implementation of the filter — it contains theory, C++ source code, programming instructions and sample application. The application demonstrates the capability of the median filter to restore images corrupted by destructive noise. This is not the only kind of corruption the filter can filter out. Download the sample and try this “miracle” of image processing science. Generator of destructive noise and sample image are also supplied.

That is not so easy to rotate the image in the screen because the screen picture is discrete. So what is the way? One should use special algorithms to calculate antialiased image. This sample demonstrates antialiased image rotation. You can process any 24-bit BMP file.

Note. The sample is a part of a production project.
This sample demonstrates solving of the problem of optimal control theory. It is pure MatLab calculation sample.

Mean filter, or average filter maybe is the simplest filter of linear class. Nevertheless, it is used widely in signal and image processing, usually as a part of processing pipeline for signal (image) averaging and preparing it for further processing. The article is a practical introduction to this useful tool — it contains theory, C++ source code, programming instructions and sample application for demonstrating filter features.
