Title: 2D and 3D Surface Texture Comparisons Using Autocorrelation Functions
Published: January 01, 2005
Abstract: Autocorrelation and cross-correlation functions are proposed for 2D and 3D surface texture comparisons. At the maximum correlaton point of the two correlated surface textrues, there is a peak shown at the cross-correaltion curve. It is proposed to generate a difference function at the maximum corelation point for evaluation of the difference between the two compared surface textures. Based on this method, the National Institute of Standards and Technology (NIST) bullet signature measurement system is developed for the bullet signature measurments of NIST standard bullets.
