description

Maģistra darba mērķis ir apskatīt skaitliskās optimizācijas metožu pielietojumu attēlu rekonstrukcijā. Uzdevums ir izmantot šādas metodes, lai pētītu kā attēlu iespējams rekonstruēt no tā pamatlīnijām, ko cilvēks uztver kā galvenās. Kā ieejas dati tiek apskatītas kores un ieplakas kā arī attēla robežas un to neliela apkārtne. Tiek pētīts kā, ar atsevišķi konstruētu minimizējamo gluduma izmaksu funkciju, ņemot vērā dažādi uzdotus nosacījumus un ierobežojumus, kas arī izmantoti ieejas datu iegūšanā, un, izmantojot barjeras tipa minimizācijas metodi liela izmēra problēmām, var rekonstruēt attēlu pēc iespējas tuvu oriģinālam. Iegūtie rezultāti labi atbilst sagaidāmajiem un no tiem ir ieguti secinājumi par veidiem, kā uzlabot minimizācijas optimizācijas darbību. Atslēgvārdi: skaitliskā optimizācija, lielu problēmu minimizācijas metode, attēla rekonstrukcija
