Algoritma Penyisipan Frame untuk Peningkatan Akurasi Metode Aligned Peak Signal-to-Noise Ratio dalam Pengukuran Kualitas Video
Abstract
Pengukuran kualitas video secara objektif mampu mengatasi kekurangan penilaian kualitas secara subjektif dalam hal waktu dan tenaga yang dibutuhkan. Pengukuran secara objektif ini menggunakan sinyal video, noise, dan parameter encoder untuk memperkirakan kualitas yang dirasakan penonton. Peak Signal-to-Noise Ratio (PSNR) merupakan salah satu metode pengukuran secara objektif yang cukup populer. Tetapi, metode PSNR yang konvensional memiliki ketidak-akurasian ketika mengukur video yang ditransmisikan melalui jaringan nirkabel dan mobile. Ini dikarenakan adanya paket hilang yang bisa menyebabkan hilangnya frame video. Pada tulisan ini dipaparkan rancangan sebuah algoritma penyisipan frame untuk meningkatkan akurasi metode PSNR. Percobaan telah dilakukan untuk menguji algoritma yang dirancang. Hasilnya percobaan menunjukkan PSNR dengan algoritma penyisipan frame mampu mencapai nilai PMCC sebesar 0.86. Dengan kata lain, akurasi PSNR konvensional telah mengalami peningkatan dengan adanya algoritma penyisipan frame.Downloads
