Questions and Answers

What does the optical flow problem aim to estimate?

  • The depth of the image pixels in a video sequence
  • The motion of each pixel between two consecutive image frames (correct)
  • The color changes between two consecutive image frames
  • The size of each pixel in the image frames

    • What is the goal of optical flow?

  • Measuring the color intensity changes in a single image frame
  • Determining the time duration between two consecutive image frames
  • Calculating the 3D structure of objects in a video sequence
  • Estimating the apparent 2D image motion of pixels from one frame to the next in a video sequence (correct)

    • What does the optical flow constraint equation represent?

  • The mathematical relationship between image pixel values and their motion components (correct)
  • The calculation of pixel size changes in a video sequence
  • The determination of object boundaries in an image frame
