Transformasi Geometri Rotasi Citra Digital Untuk Mendapatkan Kompresi Optimal Menggunakan Metode Lossless Dan Lossy

Data has a fairly important meaning, because it contains the information needed. Besides being important, process of data exchange and storage certainly requires space high costs. For this reason, compression is an interesting topic for continuous research. The success previous research in obtaining optimal compression, will be more interesting, if tested on Lossless Lossy Compression Methods, which two methods results compression. amount ratio without image rotation process. regular images obtained Huffman Ratio 48.7076% Wavelet 47.3888%. If we compare by comparing initial file size playback compared with final after 90 degrees playback, 61.03%. Meanwhile, irregular images, 49.79% was at 180 rotation. both rotation, than Compression.
