  1. Rapid Image Completion System UsingMultiresolution Patch-Based Directionaland Nondirectional Approaches Chih-Wei Fang and Jenn-Jier James Lien, Member, IEEE

  2. I.INTRODUCTION Removing these objects from the foreground leaves holes in the photograph * Training process * Image completion process

  3. II. TRAINING PROCESS A. Multiresolution Preprocessing • The background regions in each image are denoted as and are defined as • The foreground Fi regions are defined as L : down-sampled times αi : inverse mattes (1 or 0)

  4. II. TRAINING PROCESS B. Patch-Based Eigenspace Creation Based on Total M O-shape Patterns Associated With Levels 1 to L K = 2ω ( Wp + Hp ) – 4ω ×ω

  5. II. TRAINING PROCESS B. Patch-Based Eigenspace Creation Based on Total M O-shape Patterns Associated With Levels 1 to L 2009/12/16 5

  6. II. TRAINING PROCESS B. Patch-Based Eigenspace Creation Based on Total M O-shape Patterns Associated With Levels 1 to L 2009/12/16 6

  7. II. TRAINING PROCESS C. Weight Vector Creation by Projecting Corresponding O-Shape Pattern Onto First N Eigenvectors P : k -dimensional O-shape pattern vector O ( O = ( O1,O2….Ok ) )轉置 2009/12/16 7

  8. III. REPLACED A. Level L: Synthesis Value Initialization • the composite image Ci Ii is the original image Ii is the synthesized image.

  9. III. REPLACED • B. Levels L-1 to 0 : HMDV V for Directional and Nondirectional Image Completion Processes • The Hessian matrix decision value (HMDV) V : ε = 0.0001 λ: Hessian matrix

  10. 1) Level L-1 : Directional Image Completion Process for Synthesis of Texture Structure (>= threshold) 2) Levels L-1 to 1: Nondirectional Image Completion Process for Synthesis of Detailed Features III.
