  1. Texture Synthesis and Transfer William Wedler 15-463 Final Project Fall 2007

  2. Project Description • Synthetic texture from a given sample • Extract blocks and fit them together • Find blocks that match along their borders • Piece together with jagged edges • Justification: Markov property • Current state is (x,y) location • Output is a block from the given sample

  3. Synthesis Results Markov Model Current State: Overlapping region already synthesized (Shaded region) Current Output: Selected block from input sample (Dashed outline) Input Output

  4. Dependency on Sampling Parameters 20 pixel Window 30 pixel Window 40 pixel Window Input: 1/6 Overlap 1/5 Overlap 1/4 Overlap

  5. Texture Transfer Results • Modify model sates: • Add target correspondence information & Input texture Input target

  6. Extension Into Animation • Idea: Transition from mostly texture to mostly target figure • Vary resemblance to texture/target • Change window size with • Blur input target • Add time dimension to state information: • Consider texture from previous frame • Modified code borrowed from Proff. Efros

  7. Animation Results Only vary window sizes, no prev. frame info: http://www.youtube.com/watch?v=lXxkgA65TO4 Vary window, blur and add prev. frame info: http://www.youtube.com/watch?v=IrA6YKrKOPw Inputs: Outputs:
