| Abstract: | In this paper,the characteristics of the image directionality in spatial domain and frequency domain has been studied.Firstly,the spatial domain and frequency domain model of images were set up.The mathematical analysis of the charecteristics of both was carried out and verified through the simulation experiments.It's shown that,the correlation between the two is definite.This plays a crucial role in frequency domain analysis of image. |
