Homework Optical Flow, due 11-07-05

• 3 short sequences to process walk, worms,
  foreman, convert into grayscale
• Pick (any) 4 successive frames from each sequence
• Estimate the optical flow fields (for the 3
  transitions)
• Look at the results and
• Display the optical flow fields on each previous
  frame
• Predict each next frame based on the previous
  frame and optical flow display the predicted and
  actual next frame
• Compute the MSE between the predicted and actual
  frames.
• Describe your results in short
• How bad your optical flow and the predicted
  frames are? Where (in what kind of image
  regions)?
• What is the main sources of inaccuracies for each
  case?
