Penerapan Algoritma Even-Rodeh Pada Aplikasi Kompresi File Gambar

Abstract

Some image files are very large in size. So it requires a large memory storage capacity too, this is certainly a lot of costs that must be spent on the storage media. With the existence of a very large image file size in the process of sending image data files can fail because the storage media exceeds the maximum limit. The above problems can be overcome by performing the process of compressing large image files into small sizes or can reduce the bit size contained in each image file thereby saving storage containers and simplifying the process of transferring image files to other storage media. The solution to this problem is how the image file can be compressed in order to speed up the transfer and storage of image files. Image file compression aims to reduce or reduce the size of the file but does not eliminate the information data in it. With the compression technique, the data was initially large so that the size of the data can be reduced so as to save storage allocation space. In this study using the Even-Rodeh Code algorithm, using the method results in very good compression in tramisi data and transfer of image file allocation easier and faster.Keywords: Image File Compression, Event Rode Code Algorithm

“…Kompresi data menjadi sangat penting karena memperkecil kebutuhan penyimpanan data, mempercepat pengiriman data, memperkecil kebutuhan bandwidth.Teknik kompresi bisa dilakukan terhadap data teks/biner, gambar (JPEG, PNG, TIFF), audio (MP3, AAC, RMA, WMA), dan video (MPEG, H261, H263). [5]…”

Performance Comparison Analysis of the Elias Delta Code Algorithm with the Even Rodeh Code Algorithm for Compressing Image Files

“…The Even Rode Code algorithm is an algorithm used for data compression whose coding uses characters with several series of bits representing the character based on the frequency of each character [7]. The even-rodeh code is almost the same as the omega code, the difference is that the length of the code is sustained until the 3-bit length is reached and becomes the leftmost code group [2]. Here are the steps for compressing files using the even rode code algorithm.…”

“…Calculates the length of the bits b. If the bit length is the value of n, it is converted to binary, by adding a 0 right in front of the binary value so that the bit becomes 3 digits c. If the bit length is the value of n, it is converted into binary, by adding a 0 just behind the binary value so that the bit becomes 4 digits d. If the bit length of the value n is converted into binary, by adding 0 to the right of the binary value then the number is added in front of the binary value as many as the number of digits in the binary value [2].…”

“…Among them is the research conducted by Ledi Vania Simanjuntak in 2020 regarding "Comparison of the Elias Delta Code Algorithm with Levenstein for Text File Compression" which has the result that the Elias Delta Code algorithm has the highest Space Saving of 6.75% [1]. Agus Adi Pramadi, Surya Darma Nasution, Bister Purba in 2019 regarding "Application of the Even Rodeh Algorithm in Image File Compression Applications" that image file compression can be designed and built using the Microsoft Visual Studio 2008 programming language [2]. Meanwhile, research conducted by Nadia Fariza Rizky, Surya Darma Nasution, Fadlina in 2020 on "Application of the Elias Delta Codes Algorithm in Text File Compression" explains that text files that have a larger size can be compressed into a smaller size [3].…”

“…Image or image is a very important component to convey messages objectively by visualizing it through the multimedia tools used. Images or images are also very different from other data such as documents or text[2].…”
