Kev siv ntau tshaj plaws ntawm wavelets yog nyob rau hauv cov ntawv thov ua haujlwm. … Yog hais tias peb txaus siab rau qhov tsawg zaus thiab yog li muab pov tseg qhov siab zaus ib feem, qhov tseem tshuav yog ib tug smoother sawv cev ntawm tus thawj lub teeb liab nrog nws cov tsawg zaus Cheebtsam.
Vim li cas siv wavelet?
Ib lub wavelet yog kev ua lej siv los faib cov haujlwm muab lossis lub sijhawm txuas ntxiv mus rau cov ntsuas sib txawvFeem ntau ib tus tuaj yeem muab ntau zaus rau txhua qhov ntsuas. Txhua qhov ntsuas qhov ntsuas tuaj yeem kawm nrog qhov kev daws teeb meem uas phim nws qhov ntsuas.
wavelets ua haujlwm li cas?
Lub wavelet muaj nuj nqi muaj ob qhov tseem ceeb: scaling a thiab translation b. Ib qho kev ntsuas ntsuas ntawm qhov muaj nuj nqi ψ(t) nrog qhov ntsuas qhov ntsuas ntawm a yog txhais ua ψ (t / a). Xav txog ib qho kev ua haujlwm yooj yim ψ(t)=sin(ωt) thaum a=1. Thaum a > 1, ψ(t)=sin(ωt/a) yog qhov ntsuas qhov ua haujlwm nrog zaus tsawg dua ω rad/s.
Qhov txiaj ntsig ntawm wavelet transform yog dab tsi?
Ib qho ntawm qhov zoo tshaj plaws ntawm wavelets yog lawv muab ib qho chaw nyob ib txhij nyob rau hauv lub sij hawm thiab zaus domain Qhov thib ob lub ntsiab zoo ntawm wavelets yog tias, siv ceev wavelet transform, nws yog. xam sai heev. Wavelets muaj qhov txiaj ntsig zoo ntawm kev muaj peev xwm cais cov ntsiab lus zoo hauv lub teeb liab.
Vim li cas wavelet transform yog siv hauv kev ua cov teeb liab?
Wavelets yog siv tau rau kev tshuaj xyuas aperiodic, suab nrov hauv ob lub sijhawm thiab zaus sau ib txhij … Cov txheej txheem no hu ua wavelet transform. Tus txheej txheem ntawm kev hloov cov teeb liab decomposed rau thawj nthwv dej yog hu ua inverse wavelet transform. Muaj ob txoj hauv kev uas cov wavelets yog manipulated.

A tableau tuaj yeem siv tau sai sai tsim ib qho chaw uas muaj ntau tus cim. Vim tias tsis muaj kev txav mus los, lub tableau yooj yim los tswj dua li tag nrho pawg improvisation - tseem tuaj yeem ua tau yooj yim ua rau kev ua yeeb yam txuas ntxiv .
Vim li cas peb thiaj siv cov khoom siv?
Functors: Cov Khoom Ua Haujlwm hauv C ++ Ob C thiab C ++ txhawb nqa kev ua haujlwm, uas muab txoj hauv kev los hla cov lus qhia txog kev ua haujlwm li cas. Tab sis cov ntsiab lus ua haujlwm yog txwv vim tias cov haujlwm yuav tsum tau teev meej tag nrho ntawm lub sijhawm sib sau .
Vim li cas cov neeg siv khoom thiab cov khoom siv tau siv hauv c ++?
Lub hom phiaj ntawm kev siv getters thiab setters yog txhawm rau zais cov ntaub ntawv khaws cia thiab rov qab li casTxoj kev no, yog tias koj hloov tus cwj pwm, koj tsis tas yuav hloov tus lej. nyob rau hauv ib txhiab qhov chaw. Tab sis, yog tias koj tsis tas yuav hloov qhov kev siv, koj tau ua koj cov cai ntau dua thiab tau txais me ntsis los ntawm kev ua li ntawd .
