	Convolution - Wikipedia, the free encyclopedia
		In mathematics and in particular, functional analysis, convolution is a mathematical operator which takes two functions f and g and produces a third function that in a sense represents the amount of overlap between f and a reversed and translated version of g.
		An out-of-focus photograph is the convolution of the sharp image with the blur circle formed by the iris diaphragm.

		In the theory of random walks, it is notable that the central binomial coefficients ${2n \choose n}$ count the number of walks of three different special types, which may be described as `balanced', `non-negative' and `non-zero'.
		One of these coincidences is equivalent to the well-known convolution identity \[ \sum_{p+q=n} {2p \choose p}{2q \choose q} = 2^{2n}.
		In particular, new natural bijections for the convolution identity based on the unifying idea of Catalan factorization are described.
