Please put your name here:
Name: .......

Problem 1.1

Calculate Frames-per-Second (FPS) (Points 30)

  1. Fork the current repository
  2. Study the new framework-code of
    • main.cpp
  3. Check that the code is running correctly: it should show the video stream from the web-camera of your laptop.
  4. Calculate average fps and print it to console every 2 seconds. Compare Debug and Release versions.

Note

MacOS users may need to launch the application with the administrator rights, to grant access to the web-camera.

Problem 1.2

Face detection (Points 70)

  1. Read the OpenCV documentation about Viola-Jones face detector: Cascade Classifier
  2. Implement face detection for the video stream from the web-camera using the cv::CascadeClassifier class.
  3. Measure the FPS one more time. How FPS changed after incorporating the face detection into the framework?

Note

Please do not copy-paste the example code from the OpenCV documentation, but try to understand the example code and implement the solution to the problem by yourself.
