1 Introduction to th Fourir transform Computr Vision & Digital Imag Procssing Fourir Transform Lt f(x) b a continuous function of a ral variabl x Th Fourir transform of f(x), dnotd by I {f(x)} is givn by: I{ f ( x)} f ( x)xp[ jπux whr j Givn, f(x) can b obtaind by using th invrs Fourir transform: I { } f ( x) xp[ jπux du. + Dr. D. J. Jackson Lctur 8- Dr. D. J. Jackson Lctur 8- Ths two quations, calld th Fourir transform pair, xist if f(x) is continuous and intgrabl and is intgrabl. Ths conditions ar almost always satisfid in practic. W ar concrnd with functions f(x) which ar ral, howvr th Fourir transform of a ral function is, gnrally, complx. So, F ( R( + ji ( whr R( and I( dnot th ral and imaginary componnts of rspctivly. Exprssd in xponntial form, is: whr F ( R ( + I ( ϕ( tan I( R( jϕ ( Th magnitud function is calld th Fourir spctrum of f(x) ϕ( is th phas angl. Dr. D. J. Jackson Lctur 8-3 Dr. D. J. Jackson Lctur 8- Th squar of th spctrum, P( R ( + I ( is commonly calld th powr spctrum (or th spctral dnsit of f(x). Th variabl u is oftn calld th frquncy variabl. This nam ariss from th xprssion of th xponntial trm xp[-jπux in trms of sins and cosins (from Eulr s formula): Intrprting th intgral in th Fourir transform quation as a limit summation of discrt trms mak it obvious that: is composd of an infinit sum of sin and cosin trms. Each valu of u dtrmins th frquncy of its corrsponding sin-cosin pair. xp[ jπux cos(πux) j sin(πux) Dr. D. J. Jackson Lctur 8-5 Dr. D. J. Jackson Lctur 8-6
