What is the purpose of this course?
This course provides an intensive treatment of a cross-section of the key elements of computer vision, with an emphasis on implementing them in modern programming environments, and using them to solve real-world problems. The course will begin with the fundamentals of image processing and image filtering, but will quickly build to cover more advanced topics, including image segmentation, object detection and recognition, face detection, content-based image retrieval, artificial neural networks, convolutional neural networks, generative adversarial networks and much more. A key focus of the course is on providing students with not only theory but also hands-on practice of building their computer vision applications.

Labs/seminar classes points are divided into Quizzes and lab participation. Quizzes is 10% and two worst will be dropped. Lab homework is 10%. Interim performance assessment contains project with 20% weightage of the whole course. Exams will be conducted in theory and practical mode.
Late Submission Policy will be strictly applied in this course. Late submission automatically lowered one grade. If a personal emergency should arise that affects your ability, you must contact the course instructor BEFORE the deadline to get a “Special Late Submission Approval" from the course instructor. No “Special Late Submission Approval” will be granted after the deadline. There are no makeup quizzes.
