Abstract :
In this study, a novel direction selection method using the two dimensional complex discrete wavelet transform is proposed. In order to achieve arbitrary direction selection, direction extraction filters are designed. And then, this method is applied to the surface analysis of a wafer, and it is confirmed that our method is effective in detecting irregular direction components.
