Tasvirlarni siqishda yangi yondashuvlar
Abstract
Maqolada raqamli tasvirlarni siqishda diskret kosinus almashtirish (DCT) va diskret veyvlet almashtirish (DWT) usullarining qiyosiy tahlili keltirilgan. Ikkala yondashuv matematik jihatdan asoslangan, Python tilida amalga oshirilgan va turli koeffitsiyent saqlash ulushlarida tajriba o‘tkazilgan. Sifat (PSNR, SSIM), siqish darajasi (CR) hamda Foydali Ish Koeffitsiyenti (FIK) bo‘yicha optimal parametr va yondashuv aniqlangan.
Kalit so‘zlar: tasvirlarni siqish, DCT, DWT, PSNR, SSIM, siqish darajasi, foydali ish koeffitsiyenti.
