This tutorial is about one of the morphological operations on images – dilation. We describe what does this operation do and how to apply it.

In this tutorial you will see how to use OpenCV function to blur an image in order to smooth it and remove any noise from it.

This tutorial will show you how to fix underexposed images by adjusting the brightness and correcting the gamma of each pixel.

This tutorial demonstrates one OpenCV function which we can use for the alpha blending of two images. Using this function is pretty easy.
