CSE 527: Introduction to Computer Vision
Location and time: Mon, Fri 1:00 - 2:20, Room: ENGINEERING 143
In this course students will gain knowledge of theory and practice in Computer Vision, and by the end will have demonstrable ability to implement a working solution for real-world problems in image and video analysis. Students will get hands-on experience in deriving the mathematical underpinnings as well as the programmatic implementation of classical vision problems such as image classification, object detection and tracking, segmentation, pose estimation, visual scene reasoning (e.g. captioning, questioning) and more. Students will utilize deep neural networks of many types (convolutional, residual, recurrent, variational, adversarial, etc.), learn how to use cloud1 GPU-enabled virtual machines, evaluate their implementations on standard vision datasets, and compare their results to the state-of-the-art work of computer vision laboratories worldwide. This is an intensive hands-on class with weekly theoretical and practical programming assignments, which will give students the confidence to tackle computer vision problems in the wild as professionals.

Deep Learning with Python
Machine learning, data science books: https://github.com/faizalazman/Data-Science-Books
- Solid programming experience required: In this course you will program complete computer vision systems, from reading dataset files and processing pixels through coding an optimization problem. You should be comfortable picking up a new API (with some help). We will be working strictly in Python3 (OpenCV, NumPy, SciKit, TensorFlow/Keras, Jupyter). If you are uncomfortable in Python - please contact me.
- Mathematics -- relevant knowledge required: This course relies on an established knowledge in computer science oriented mathematics. You are assumed to have taken undergraduate-level courses in the following: Calculus, Linear Algebra, Probability Theory, and Algorithms.
- Machine learning experience very useful (but not required): Coding projects will usually have a machine learning component to them. It would be beneficial if you are familiar with basic ML pipelines (feature design, training, testing) and concepts (supervision, classification, regression, clustering, confusion matrices, precision-recall, ROC, AUC, F1 score, loss/gain functions, etc.)
If you have no solid programming2 background or no solid understanding of linear algebra3 and algorithms4, you should not take this course.
If you do not have any experience in machine learning:
- Take an online course, for example:
- Pick up a book: http://amzn.to/2uqRlxy, http://amzn.to/2t3vOY2
- Good list of resources for machine learning oriented linear algebra and other maths: https://machinelearningmastery.com/resources-for-linear-algebra-in-machine-learning/
- Be prepared to do a lot of self-learning.
- You must be comfortable with learning a sizable set of new tools and processes quickly, and putting them to work right away. In other words, you are expected to be a Hacker :)
- If you have a concern regarding your prior knowledge - contact me.
2 "solid programming" means you are capable of writing, documenting, running, debugging and analyzing the complexity of a program in Python given a non-trivial task at hand.
3 "solid linear algebra" means you have full grasp of concepts such as vectors, matrices, bases, operations, normalization, dot and cross products, factorizations, etc. and are able to derive equations by hand.
4 "solid algorithms" means you have full grasp of elementary data structures (lists, sets, vectors, trees, stacks, queue, hash tables), sorting, graph theory, combinatorics, dynamic programming and complexity analysis.
In this class grading will be given according to:
- Attendance: Record of attendance will be kept in class. More than 5 absences (~20%), without just and confirmed cause5, will award a failing grade in the entire course. Grade component: 10%.
- Assignments: Students are expected to complete all assignments. Missing assignments will award a failing grade for them. More than 3 missing assignments throughout the semester will award a failing grade in the entire course. Grade component: 35%.
- Late submission: Assignments will be accepted only up to 48 hours past deadline. Each hour beyond the deadline will account for a 1.5% penalty decrease in grade.
- Mid-term: Students are expected to complete the mid-term. Missing the mid-term will not award a failing grade for the entire course. Grade component: 25%.
- Final: Students are expected to complete the final to graduate from the class with a passing grade. Failing or missing the final might still award a passing grade in the entire course, but it's extremely unlikely. Grade component: 30%.
