Lecture details

Continuous and Discrete Image Reconstruction (Dr. Péter Balázs)

Computerized Tomography (CT) was originally a method of diagnostic radiology to obtain the density distribution within the human body based on X-ray projection samples. From a mathematical point of view it seeks to determine an unknown function defined over the 3D Euclidean space from weighted integrals over subspaces, called projections. Since the values of the function can vary over a wide range, a huge number of projections are needed to ensure an accurate reconstruction. In the first part of the lecture we introduce two widely used methods to solve the above mentioned image reconstruction problem.

There are applications where the aim is to reconstruct objects from just a small number of their projections, e.g., in industrial non-destructive quality testing or in Electron Tomography. Here, CT reconstruction methods are no longer successfully applicable. However, there is still a chance to get an accurate reconstruction from just a small number of projections, by exploiting prior knowledge that the range of the image function is discrete and consists of only a small number of known values. This leads us to the field of Discrete Tomography that will be discussed in the second part of the lecture.

During the practical session, we study continuous and discrete methods to reconstruct objects from their projections, under different circumstances.

Task-oriented Computer Vision in 2D and 3D (Dr. Csaba Beleznai)

Applications of Computer Vision slowly make the step towards practical use under demanding real-world conditions. This talk presents considerations from scientific and practitioner’s point of view describing the process how a solution for a given task can be accomplished. These aspects are illustrated by a number of application examples targeting some selected challenging vision problems such as text detection and recognition in cluttered environments, video analytics and 3D vision-based characterization of crowd movement. The talk attempts to provide a look under the hood of these systems by detailing considerations for the algorithmic choice, describing employed algorithmic concepts, presenting relevant implementation details, putting special emphasis on the interplay between Matlab and C++ for a rapid development process and demonstrating numerous results of completed real-time 2D and 3D vision systems.

During the practical part of this presentation we will jointly investigate and solve some 2D/3D analysis tasks in Matlab, for detecting humans in depth data computed from stereo vision image pairs.

Industrial Image Processing (Dr. Gábor Németh)

Industrial Image Processing is special field of digital image processing including the following topics:

  • Special Lenses used in industries for image processing.
  • Camera Calibration
  • Feature point detection, description and matching.
  • Epipolar geometry
  • 3D reconstruction
  • Optical flow
  • Visual measurement

In this course we are going to learn the features and usage of special lenses. Then we are going to deal with visual measurement in a lab course. The course consists of 1 hour of lecture and 3 hours experimental lab course.

Medical image processing using deep learning techniques (Dr. László Ruskó)

In the daily routine of medical imaging the number of cases is rapidly increasing which challenges the radiology departments in healthcare. Since the human resourced are limited, there is an increasing demand for automated (pre)processing of medical images. Deep leaning techniques were proved to be efficient in solving various image processing problems such as character recognition, face detection, or photo classification. As result of the technology improvement (in GPU computation power) of the recent years we can train complex deep-learning models for automated processing of large (high-resolution or 3-dimensional) images. Thus, medical image classification (based on pathology) and segmentation (of organs or lesions) became a highlighted research field in computer science. This lecture will present example for a classification and a segmentation problem which were solved using deep learning technique.
