• 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.

• 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.

The course follows an interactive and hands-on teaching modality with a strong emphasis on practical aspects. On top of the laboratory sessions, customarily held after most lectures, the course leverages project-based learning to enable students to apply the principles covered during lectures to real-world computer vision tasks. During the Practical Sessions, carefully selected sample codes will cover the key components of computer vision and image processing, as well as deep learning (convolutional neural networks for image classification, segmentation, object recognition, and image generation). Students are encouraged to follow along and experiment with the code to gain a solid grasp of the underpinning concepts. Projects are assigned to groups to foster a deeper understanding of the subject. The students are divided into teams, and will phase two step-projects. The first phase, which will take place during the first half of the course, is meant to teach the students how to use CNN models for solving a basic visual recognition task. In the second phase, students are invited to choose a specific computer vision problem to be solved by Geometric Computer Vision/Image Processing techniques *and* advanced deep learning models. The projects need to be diverse among the teams, challenging, and relevant to current real-world applications. During the project development, students are expected to take advantage of the methods and skills presented during lectures for solving their specific task. At the end of the course, each team presents their projects to the entire class. This presentation fosters a collaborative learning environment where teams can learn from each other's successes and challenges.

Individual assignments test the students' skills about:

- 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 

- develop new pipelines adapting to the specific problem at hand 

The written exam will also test the students' proficiency in

- comparing the various models and find the most relevant to be applied in the specific problem 

- examinin the selected model in order to balance performance, computational complexity and overfitting 

- discussing the pros and cons of different Computer Vision techniques for a specific problem 

Slides and Links to reference papers will be distributed. Also Colab notebooks will be provided.
