Abstract

Ushbu maqolada Haar toʻlqin usulidan foydalangan holda tasvir va signal siqish uchun chegaraviy qiymatlarni tanlash metodlari tadqiq qilinadi. Thresholding (chegaraviy qiymat tanlash) usuli siqish jarayonining samaradorligi va sifatini oshirishda muhim ahamiyatga ega. Maqolada adaptiv thresholding va global thresholding metodlari keltirilgan. Adaptiv thresholding usuli signal yoki tasvirning turli qismlariga mos chegara qiymatini tanlab, shovqinni kamaytirishga va tasvir sifatini saqlashga imkon beradi. Global thresholding esa umumiy chegara qiymatidan foydalangan holda koeffitsientlarni saralash usulini o'z ichiga oladi. Maqolada keltirilgan usullarning afzalliklari va kamchiliklari tahlil qilinib, Haar toʻlqin koeffitsientlari uchun eng samarali chegara tanlash algoritmi ishlab chiqiladi.
