A research and simulation of Fourier transform of digital image
Renjie Zhang · Optical Instruments · 2009
In order to find new method of digital image processing,frequency spectrum is researched in the paper.Especially,research the effect of amplitude spectrum.The research includes high-frequency study and low-frequency study.In addition,MatLab simulation is given.The study of amplitude spectrum is especially important,which is the base of further research for digital image processing.
