  1. FPGA BASED REAL TIME VIDEO PROCESSING Characterization presentation Presented by: Roman Kofman Sergey Kleyman Supervisor: Mike Sumszyk

  2. AGENDA

  3. Project Objectives

  4. Algorithm • Based on the 2D non-linear Diffusion equation • Iterative solution. • Good Filtering – smoothes noises. • Keeps borders intact.

  5. Matlab simulation Filtered image Original image dt=4 , 4 iterations

  6. Schemes Explicit Semi implicit • Stable for small time steps. • Good results requires many iterations. • Simple implementation. • Stable for all time steps. • Good results after several iterations. • High computational and storage effort (Thomas).
