Mission & Content Summary

MISSION

In recent years, computer vision and image processing have gained a lot of attention, thanks to the advent of deep neural networks. These machine learning models have demonstrated outstanding performance in solving many complex tasks, achieving results that were impossible-to-believe a few years ago. Specifically, in many Computer Vision applications, like Image Recognition, Object Recognition, Image Segmentation and Image Generation, deep learning approaches outperform traditional hand-crafted algorithms, approaching human performance. This course aims at providing a clear understanding on how it is possible to make computers interpret and analyze digital images. Students will become acquainted with the theoretical background and the practical skills to understand and use Deep Learning models, and in particular Convolutional Neural Networks, for solving visual recognition problems. On top of that, the course covers the basic principles of Geometric Computer Vision and of Image Processing, to provide a solid ground for imaging specialists, who can recognize whether a problem at hand needs to be solved using deep learning or on traditional techniques. Overall, this course offers a broad overview in Computer Vision and Image Processing, illustrating the flagship problems addressed in these domains. Particular emphasis will be given to the image formation process both from a geometric (pinhole camera) and photometric (sensor noise) perspective.

● Self-supervised Learning

● Generative Models

● Emerging Topics in Vision: Video Understanding, 3D Perception, Multi-modal Models


Intended Learning Outcomes (ILO)

KNOWLEDGE AND UNDERSTANDING

At the end of the course student will be able to...
  • Determine whether a given imaging problem needs to be solved by traditional Computer Vision / Image Processing techniques or by Deep Learning models. Identify then the right CNN architecture to solve different visual recognition problems.
  • Recognize the best practices for CNN training.
  • Describe and get inspiration from the most successful Deep Learning architectures,
  • Explain the most successful Computer Vision applications to be solved by Deep Learning models.
  • Illustrate complex techniques beyond the fundamental ones presented during lectures.

APPLYING KNOWLEDGE AND UNDERSTANDING

At the end of the course student will be able to...
  • Analyze a specific Computer Vision problem and find which model best solves the task at hand.
  • Use fundamental deep learning algorithms for Computer Vision autonomously.
  • Compare the various models and find the most relevant to be applied in the specific problem.
  • Examine the selected model in order to balance performance, computational complexity and overfitting.
  • Discuss the pros and cons of different Computer Vision techniques for a specific problem.
  • Develop new pipelines adapting to the specific problem at hand.

Teaching methods

  • Practical Exercises
  • Collaborative Works / Assignments

DETAILS

The course adopts an interactive, hands-on teaching approach with a strong emphasis on practical application. In addition to laboratory sessions (customarily held after most lectures) the course integrates project-based learning, enabling students to apply the concepts introduced in class to real-world computer vision tasks. During the Practical Sessions, carefully curated sample code illustrates the fundamental components of computer vision, image processing, and deep learning techniques, including convolutional neural networks and Transformers for classification, segmentation, object detection, and image generation. Students are encouraged to follow along, modify the code, and experiment, thereby gaining a solid understanding of the underlying principles. Project work is carried out in teams to promote collaboration and deepen conceptual understanding.

Students complete a two-phase project:

● Phase 1 (first half of the course): students learn to apply geometric computer vision and image processing techniques to solve a basic 3D reconstruction task.

● Phase 2: teams select a specific computer vision problem to be addressed using deep learning models. Projects must be diverse across teams, sufficiently challenging, and aligned with current real-world applications.

 

Throughout the project development, students are expected to draw upon the methods and skills covered during the lectures to design and implement effective solutions. At the end of the course, each team presents its project to the class, fostering a collaborative learning environment where students benefit from one another’s insights, approaches, and challenges.


Assessment methods

  Continuous assessment Partial exams General exam
  • Written individual exam (traditional/online)

  • Individual Works/ Assignment (report, exercise, presentation, project work etc.)

ATTENDING AND NOT ATTENDING STUDENTS

Project assignments evaluate the students’ ability to:

● analyze a specific Computer Vision problem and identify the model that best addresses the task at hand;

● apply fundamental deep learning algorithms for Computer Vision autonomously;

● design and develop new pipelines tailored to the requirements of the given problem.

 

The written exam assesses the students’ proficiency in the topics covered throughout the course. The distinction between attending and non-attending students is based solely on project completion: attending students complete the project and receive a discount on the written exam (i.e., a reduction in the number of points to be answered), non-attending students are evaluated exclusively through the written exam.
