OVERVIEW

The course is about image processing and computer vision techniques for 3D static and dynamic scene interpretation and to discuss applications  to object tracking, depth perception, object recognition and automatic guidance 

AIMS AND CONTENT

LEARNING OUTCOMES

The course aims at providing knowledge on theory and tools on the basics of Computer Vision, for the extraction of semantic and geometric information about a scene from an image or a sequence of images. Topics of interest include: camera models and image formation; camera calibration; connection between 2D images and 3D scene structures; image processing basics as image filtering, local features extraction (edge, corner, blob), including the use of multi-scale image representations; image matching, with reference to classification and retrieval problems; stereo vision and scene depth estimation; motion detection in image sequences, including change detection and optical flow estimation.

AIMS AND LEARNING OUTCOMES

The aim of the course is to provide a broad introduction to different core aspects of computer vision, including  camera modelling, camera calibration, image processing, pose estimation, multi view geometry, visual tracking, and vision based calibration.

At the end of the course the student will be able to understand the main theoretical concepts and to design and implement classical computer vision algorithms. The course will also provide an overview of the main application domains, with a special reference to the robotics scenario.

PREREQUISITES

Background knowledge on linear algebra and calculus; basic programming skills

TEACHING METHODS

Theoretical classes followed by hands-on activities

Working students and students with certification of DSA, disability or other special educational needs are advised to contact the
teacher at the beginning of the course to agree on teaching and exam methods which, in compliance with the teaching objectives, take into account the methods of individual learning

EXAMS

EXAM DESCRIPTION

  • 50% from a continuous assessment  through practical laboratory exercises done throughout the semester.
  • 50% from the end-semester exam, organised as follows:
    • A multiple-choice quiz (~5%) that is a threshold for attending the oral exam;
    • An oral exam (~45%).
  • It is not allowed to consult books, notes, or other written material.

ASSESSMENT METHODS

The course is organized in theory classes and practical (hands-on) classes.

Practical activities cover about 1/3 of the course. The goal of such activities is presented in class by the instructors, and should be completed by the students as a homework. They can be carried out individually or in groups; some of them are associated with an assignment and constitute a continuous assessment of the student's work.

The final assessment of the theory part is carried out through a final exam.
