1. Fractal Image Compression Lossy Looking for “local” similarities PIFS -- Partitioned Iteration Function system High compression ratio and high quality Time consuming in encoding

2. 方法 Range Pool Domain Pool 對每一個 R i, 從 Domain 中搜尋一個和 R i 為最像的子影 像, 稱為 D i. DiDiDiDi RiRiRiRi

3. Eight Orientations for Similarity

4. Reconstruction Recursion computations of PIFS Independent of initial image Zoom property

5. Base Line 和快速演算法的比較 Base line 快速演算法 壓縮時間 = 66 分鐘 PSNR= 28.9016 db 壓縮時間 = 18.2 分鐘 PSNR= 28.9012 db
