Image-blending using Python and OpenCV

Python and the OpenCV library make it very easy to work with visual input such as images or videos. In this tutorial, I discuss contents on image-blending and present a way of merging pixel information of two images. To accomplish this, I use a third image (the so-called mask), which serves as a template for the blending process. Because this template is a matrix of weighting factors, it is possible to produce results, which cannot be obtained with blending methods one usually finds on the web (or at least I did not find them).
