TASVIRLARDA DISKRET VEYVLET OʻZGARTIRISHLARNI AMALGA OSHIRISH ALGORITMI
Maqola haqida umumiy ma'lumotlar
Ushbu maqolada Diskret Veyvlet Oʻzgartirish (DWT) texnikasini tasvirlarda amalga oshirish algoritmi bayon etilgan. Tadqiqot tasvirni chastotalarga ajratish va chekka xususiyatlarni ajratib olish jarayonlarini qamrab oladi. Dastlab tasvir grayscale formatga oʻtkazilib, gistogramma tenglashtirish orqali yorqinlik darajasi optimallashtiriladi. Shundan soʻng, DWT yordamida tasvir LL, LH, HL va HH komponentlarga ajratiladi. Ushbu komponentlar yordamida tasvirning asosiy va yuqori chastotali xususiyatlari ajratib olinib, siqish va qayta tiklash jarayonlari amalga oshiriladi. Mazkur algoritm tasvir sifati va siqish samaradorligini oshirishga qaratilgan.
