Homework: Optical Flow, due 11-07-05

This homework assignment involves processing three short video sequences ("walk," "worms," and "foreman") to estimate optical flow fields. You will convert each sequence into grayscale and select four successive frames from each. For the three transitions in these sequences, calculate the optical flow, display it on previous frames, and predict the subsequent frames based on optical flow analysis. Finally, compute the Mean Squared Error (MSE) between predicted and actual frames, and discuss the accuracy of your results, potential inaccuracies, and regions of interest.

  1. 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?
