A fast algorithm for cross-correlation based on velocity-measuring
Hongli Liu · Information technology newsletter · 2010
In this paper,a fast algorithm is designed on the basis of analyzing the cross-correlation algorithm.For the shortcomings of the past research,the fast algorithm changes the order of the operations of cross correlation function,and reduces the numbers of the computing in order to resolve the poor real-time in velocity-measuring.Using MATLAB simulation,the comparison of the decrease under the condition of different delay is enumerated.
