How to do the assignments

Update 23: Apr 11 : Assignment Deep Learning MNIST (Required):

Update 22: Mar 25: Optical Flow Assignment (Required):

      Here is the set of directions for installing OpenCV and doing the Optical Flow demo. 4453OpticalFlowOpenCVImplem5.pdf

      In this assignment, you will run the Optical Flow algorithm from the OpenCV Library. Follow the directions in the provided pdf notes (above) to see how to install Visual Studio 2017, the OpenCV Library, and the code that will call the appropriate modules from the library. You are expected to show a live demo of your camera running the optical flow (if this is impossible, you are allowed to run the algorithm on two frames, as shown in the pdf directions). The Optical Flow algorithm has been implemented in the library by following the theory that is presented in the paper (bouguetopticalflow.pdf in Update 21). These equations in the paper are similar to the ones discussed in our Optical Flow notes (how to get results for 3 or more points), but are derived in a different manner, and use a Pyramidal approach that is also described in the paper. (You do not need to understand that paper to obtain good experimental results). For showing your working demo, you will do a live demo with the grader, and will show that your cam is able to see a moving pattern, such as some text on a sheet of paper (that is moved slowly), and the cam window displays the optical flow vectors.

      Now that this class has moved to an on-line mode, please also check the Notifications that I send to Webcourses for the CAP4453 class. So, regularly (every 8 hours or so), please check here for Updates, and read the webcourses notifications. If you have not yet heard from me your Test Score in a phone call, you must immediately send me email with a time that I can call you or can communicate with you by webcourses Conference (which will allow us to talk with audio; to set up the webcourses Conference, you need to stay on-line after sending me an email that you are ready to spend time focusing on communicating with me). If you are stranded outside the USA, or do not have a phone, we will be able to communicate adequately by webcourses Conference. Stay safe.

Update 19: Feb 15:

      Practice Test
      In addition to this list of questions, there will be a few single-point questions that will test if the student has understood deeper issues and details about the study material.

Update 18: Feb 12:

Update 17: Feb 6 :

      Additional Opportunity time to have Sobel.c and Canny.c graded: at room HEC-234. Friday Feb 7 , from 11:00am till 1pm. There will be more times later in future weeks.

Update 16: Feb 5:

Update 15: Feb 5:

Update 14: Feb 3 :

      Opportunity times to have Sobel.c and Canny.c graded: Both times are at HEC-234. The two times are: Wednesday Feb 5 , from 9:00am till 10:15am; and Wednesday Feb 5, from 12:15pm till 2pm.

Update 9: Jan 22:

      Required Assignment Two: In this assignment, you will download and run our implementation of AdaBoost, using the positive and negative examples we have provided.

      Carefully read the steps in here,

      Unzip the zip file.
      Everything ( vboost, vdetect, positive and scenery) is included in the .zip file (positive and scenery are in ..\AdaBoost\vboost, Germany.pgm is in ..\AdaBoost). Should you run into any issues while compiling the software, or during running it, send an email to
      For judging whether you are on the right track to success with this assignment, run the test on the German Soccer Team image. After all the improvements (such as training on 2000 images of each class), your results should be such that most of the faces are found, and there are few False Positives (boxes drawn in places where there are no faces). There is no partial credit for this Assignment, you must succeed fully to get the points. For grading, you will meet the grader and show the program running and getting the result on an image that we will provide you.

Update 8: Jan 15:

      For the face detection topic, Google: viola jones robust real-time object
      Then, select the paper that is found at named viola-IJCV-01.pdf
