Preliminary pedestrian removal results

Currently, this is my pipeline to remove pedestrians:
  1. Compute homographies between two views (I1 and I2) using SIFT and RANSAC.
  2. Detect pedestrians on both views (with bounding boxes).
  3. Warp pedestrian bounding boxes using homography from step 1, determine overlap (if any).
  4. Use method proposed by James Davis to obtain a dividing boundary in overlap region.
  5. Replace pixels where a pedestrian is detected with pixels from the other (warped) view using the boundary from step 4.
Some results.

    Sameer mentioned that a gradient domain method such as Poisson image editing could be used to improve the seam problem:
