1. An additional method for merging images besides blending
2. Finding seams in images
3. Benefits of cutting images over blending images
moving objects cause “ghosting”
find on optimal seam as opposed to blend between images
final has exact pixels from an image
overlapping block -> vertical boundary
take difference between square, min error boundary
Minimum cost cut can be computed in polynomial time(max-flow/min-cut algorighms)
