Abstract

Abstrak Kompresi citra merupakan salah satu teknik pemampatan untuk membantu proses penyimpanan dan pengiriman data citra agar pekerjaan tersebut lebih efektif. Joint Photographic Experts Group (JPEG) merupakan standar kompresi internasional telah secara luas digunakan saat ini. Kompresi JPEG menggunakan berbagai algoritma dalam proses kompresinya. Dari berbagai algoritma yang ada, Huffman dan Run Length merupakan algoritma kompresi yang biasa digunakan untuk kompresi JPEG. Untuk itu, perlu diketahui algoritma mana yang lebih baik penggunaannya dalam kompresi JPEG dari kedua algoritma tersebut. Penelitian ini menggunakan bahasa pemrograman MATLAB untuk membuat suatu aplikasi kompresi citra JPEG dengan menerapkan dua algoritma, yaitu Huffman dan Run Length. Aplikasi ini menampilkan aspek ukuran file, waktu kompresi, Peak Signal to Noise Ratio (PSNR), dan rasio kompresi, yang dapat digunakan sebagai pembanding kedua algoritma kompresi yang digunakan tersebut. Kata Kunci : Kompresi Citra, Joint Photographic Experts Group (JPEG), Huffman, Run Length, MATLAB, Peak Signal to Noise Ratio (PSNR) Abstract Image comprasion is one of compression technique to make storage and sending image file more effective. Joint Photographic Experts Group (JPEG) is one of international compression standard which is commonly used. JPEG compression applies many kinds of algorithm on its compression process. Among many algorithms exists, Huffman and Run Length are compression algorithms which commonly used for JPEG compression. So it’s necessary to be informed which algorithm is better for JPEG compression between both algorithm. This research uses MATLAB programming language to make an application of JPEG compression by applying 2 (two) algorithms, Huffman and Run Length. This application shows file size, compression time, Signal to Noise Ratio (PSNR), and compression ratio aspect that will be used as comparator both compression algorithms. Keywords: Image Compression, Joint Photographic Experts Group (JPEG), Huffman, Run Length, MATLAB, Peak Signal to Noise Ratio (PSNR)
