\section{Overview}
In this chapter, after dealing with GPU median filter implementations,
-we propose to explore how convolutions can be implemented on modern

GPUs. Widely used in digital image processing filters, the \emph{convolution
operation} basically consists in taking the sum of products of elements
from two 2-D functions, letting one of the two functions move over
