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. A convolution is a kind of very general moving average, as one can see by taking one of the functions to be an indicator function of an interval.
In digital image processing, convolutional filtering plays an important role in many important algorithms in edge detection and related processes.

It is basically for convolving functions what it means is you take two functions originating from the unit diagram on the imaginary plane. You multiply them and you get the third function.

It just makes the math easier for computer programmers. It's easier to multiply 2 Fourier transforms than to figure out how to convolve crap.
