Abstract

A fast, accurate and efficient Gaussian filter implements a box filter implementation, applies the central limit theorem and uses an overflow implementation. By combining the box filter, central limit theorem and overflow, the filter is fast, accurate and efficient so that it is able to be implemented in hardware and/or software easily.
