This page shows various situations result

  1. Non-rigid motion
  2. Camera shake on inanimate object
  3. Illumination change & displacement
  4. Multiple Light Sources

“No-result” in the following images indicates the failure of correspondence search:
Conventional methods 2,3 use a correspondence algorithm of 2. However, the correspondence algorithm cannot get correspondences in some image pairs, and therefore the methods do not have a result.
