The course will take place as live web course.


Nowadays, digital images and video are everywhere. Image Processing and Analysis revolutionizes very many domains, notably:

  • Digital Media (video/image/movie) Content Production and Broadcasting, Social Media Analytics,
  • Medical/Biological/Dental Imaging and Diagnosis,
  • Big Visual Data Analytics,
  • Internet and Communications (media broadcasting, streaming).
  • Scientific Imaging of any sort, e.g., Remote Sensing, Environment Sensing.

Furthermore, our dream to make machines sense and perceive (notably see) comes true: Nowadays Computer Vision enables diverse applications:

  • Autonomous Systems (cars, drones, vessels) Perception,
  • Robotics Perception and Control,
  • Intelligent Human-Machine Interaction,
  • Anthropocentric (human-centered) Computing,
  • Smart Cities/Buildings and Assisted living.

Visual Computing, encompassing Computer Vision and Image Processing, coupled with AI (notably Machine Learning and Deep Neural Network) advances hit the news almost every day.

This two-day short course focuses on Computer Vision and Image Processing theory, their applications in the above-mentioned diverse domains and new challenges ahead. It consists of two parts (A, B) and each of them including 8 one-hour lectures and related material (slide pdfs, lecture videos, understanding questionnaires).

Part A lectures (8 hours) provide an in-depth presentation of Image Processing theory and its application in the above-mentioned diverse domains. First, an Introduction to Image Processing and Computer Vision will be offered to clarify concepts in a precise and mathematical way. Image formation and its issues (e.g., image noise, deformations) will then be detailed, whether based on visible light or on other modalities (e.g., Xrays, Ultrasound). Image sampling will provide the necessary background to understand the potential and limitations of digital images.  2D Signals and Systems will provide the theoretical and algorithmic tools for most image processing operations. Then notions related to Image transforms will be clarified, together with their applications in image/video analysis and compression.  Fast 2D convolution algorithms will provide efficient implementation of most image processing operations. Image perception will overview the Human Visual System and its impact on image quality and image processing system design specifications. Finally, Image filtering will provide tools to reduce noise and enhance image quality, e.g., to increase contrast, perform image zooming or printing. 

Part B lectures (8 hours) provide fan in-depth presentation of both 2D and 3D Computer Vision and Image Analysis theory and their applications in the above-mentioned diverse domains. Edge detection will allow to extract reliable object contours.  Region segmentation and Texture description will detail segmentation of an image into homogeneous regions. Either edge or region object descriptions will be employed in 2D object shape analysis. 3D Computer Vision starts with a detailed presentation of image acquisition and camera geometry, including camera calibration. Then, two lectures on a) Stereo and Multiview imaging and b) Structure from motion will provide the theoretical and algorithmic tools to recover 3D world models from images. They will be used on Localization and mapping that is of primary importance in Autonomous Systems and Robotic perception. Finally, Object tracking is presented, as it is of primary importance (together with object detection presented in the ML DNN e-course) in practically all the above mentioned Computer Vision applications and way beyond.

Though independent, the attendees of this short e-course will greatly benefit by attending the CVML short e-course on ‘Machine Learning and Deep Neural Networks’ 17-18th February 2021: 
CVML Short Course – Machine Learning and Deep Neural Networks

Prof. Ioannis Pitas (IEEE fellow, IEEE Distinguished Lecturer, EURASIP fellow) received the Diploma and PhD degree in Electrical Engineering, both from the Aristotle University of Thessaloniki (AUTH), Greece. Since 1994, he has been a Professor at the Department of Informatics of AUTH and Director of the Artificial Intelligence and Information Analysis (AIIA) lab. He served as a Visiting Professor at several Universities.

His current interests are in the areas of computer vision, machine learning, autonomous systems, intelligent digital media, image/video processing, human-centred computing, affective computing, 3D imaging and biomedical imaging. He has published over 1000 papers, contributed in 47 books in his areas of interest and edited or (co-)authored another 11 books. He has also been member of the program committee of many scientific conferences and workshops. In the past, he served as Associate Editor or co-Editor of 9 international journals and General or Technical Chair of 4 international conferences. He participated in 70 R&D projects, primarily funded by the European Union and is/was principal investigator/researcher in 42 such projects.
