Objectives and Contextualisation

Module Coordinator: Dr. Philippe Salembier

The aim of this module is introduce the students to computer vision including basics of human visual system and image perception, acquisition and processing. In terms of processing, the module deals with low-level pixel-based transforms, linear, nonlinear and morphological filtering, Fourier analysis, multiscale representations, extraction of simple features and image descriptions. Furthermore, elementary grouping, segmentation and classification strategies will be discussed as well as quality and assessment methodologies for image processing algorithms. To put into practice the algorithms and techniques, the students will work on a concrete project along the course. The aim is to provide an applied knowledge of a broad variety of Computer Vision techniques applied to solve a real-world vision problem. The project goal is to detect specific objects in images using basic CV techniques such as linear and non-linear filtering segmentation, grouping, template matching, modeling, etc. The knowledge obtained can be used in a wide variety of applications, for instance, quality control, generic object detection, security applications, etc.

 

Competences

  • Accept responsibilities for information and knowledge management.
  • Choose the most suitable software tools and training sets for developing solutions to problems in computer vision.
  • Conceptualise alternatives to complex solutions for vision problems and create prototypes to show the validity of the system proposed.
  • Continue the learning process, to a large extent autonomously.
  • Identify concepts and apply the most appropriate fundamental techniques for solving basic problems in computer vision.
  • Plan, develop, evaluate and manage solutions for projects in the different areas of computer vision.
  • Solve problems in new or little-known situations within broader (or multidisciplinary) contexts related to the field of study.
  • Understand, analyse and synthesise advanced knowledge in the area, and put forward innovative ideas.
  • Use acquired knowledge as a basis for originality in the application of ideas, often in a research context.
  • Work in multidisciplinary teams.

Methodology

Supervised sessions: (Synchronous online sessions)
• Lecture Sessions, where the lecturers will explain general contents about the topics. Some of them will be used to solve the problems.

Directed sessions: (Synchronous online sessions)
• Project Sessions, where the problems and goals of the projects will be presented and discussed, students will interact with the project coordinator about problems and ideas on solving the project (approx. 1 hour/week).
• Presentation Session, where the students give an oral presentation about how they have solved the project and a demo of the results.
• Exam Session, where the students are evaluated individually. Knowledge achievements and problem-solving skills

Autonomous work:
• Student will autonomously study and work with the materials derived from the lectures.
• Student will work in groups to solve the problems of the projects with deliverables:
    • Code
    • Reports
    • Oral presentations

Assessment

The final marks for this module will be computed with the following formula:

Final Mark = 0.4 x Exam + 0.55 x Project+ 0.05 x Attendance

where,

Exam: is the mark obtained in the Module Exam (must be >= 3)

Attendance: is the mark derived from the control of attendance at lectures (minimum 70%)

Projects: is the mark provided by the project coordinator based on the weekly follow-up of the project and deliverables. All accordingly with specific criteria such as:

  • Participation in discussion sessions and in team work (inter-member evaluations)
  • Delivery of mandatory and optional exercises.
  • Code development (style, comments, etc.)
  • Report (justification of the decisions in your project development)
  • Presentation (Talk and demonstrations on your project)
