Ushbu tezisda ultratovushli diagnostika apparatidan olingan o‘t pufagi tibbiy tasvirlariga raqamli ishlov berish masalasi ko‘rib chiqilgan. Tadqiqotda spekl shovqini, past kontrast va chegaralarning noaniqligi sababli yuzaga keladigan diagnostik muammolarni kamaytirish maqsadida bilateral raqamli filtr va bikubik splayn interpolatsiyasiga asoslangan takomillashtirilgan gibrid model taklif etildi. Bilateral filtr yordamida shovqin samarali bartaraf etilib, muhim strukturaviy chegaralar saqlab qolindi. Bikubik splayn interpolatsiyasi orqali tasvir aniqligi va silliqligi oshirildi. Olingan natijalar o‘t pufagi devori va toshlarini aniqlash ishonchliligi yaxshilanganini ko‘rsatadi.
