Ushbu maqolada raqamli tasvirlarda uchraydigan shovqin turlari hamda ularni kamaytirish uchun qo‘llaniladigan filtrlash usullarining samaradorligi tahlil qilinadi. Asosan chiziqli va nochiziqli filtrlash usullari – o‘rtacha (mean), median, Gauss, Wiener va bilateral filtrlardan foydalanish orqali tasvir sifatini yaxshilash masalalari ko‘rib chiqilgan. Har bir filtrning afzallik va kamchiliklari vizual hamda statistik ko‘rsatkichlar asosida solishtiriladi. Tadqiqot natijalari shuni ko‘rsatadiki, shovqin turiga mos filtrni tanlash tasvir aniqligi va axborot saqlanishiga bevosita ta’sir ko‘rsatadi
