How to detect and eliminate mismatches? Use a robust technique, e.g.\

  1. Eliminate points far from their epipolar lines after computing .
  2. Use RANSAC (random sampling consensus) approach --- compute putative using minimum number of matches (n=7), and measure support. Repeat over randomly chosen sets of 7 matches (use proximity). Choose with largest support.

Matches computed from corners alone
