IT-Systems Engineering BA


This project seminar aims at bachelor students who want to extend their image processing, computer vision, and computer graphics skills regarding the analysis, planning, and development of GPU-accelerated image and video processing techniques for mobile, desktop and server systems. The course has mainly a project character and is subdivided into two parts:

The first part of the course is organized as a lecture series. The lecture topics are specified together with the seminar students and can include an introduction to the following basic concepts and foundations to:

  • A short introduction into the field of image and video analytics,
  • Techniques for image and video processing,
  • Application development for Android and Desktop/Server systems

Using specific image and video processing operations, the course teaches how fundamental processing techniques can be designed, developed and tested.


In the second part of the course, participants will work individually, or as a team (max. 2 members), to implement assigned topics in the field of interactive image and video processing. Therefore, both a C++ and an Android or iOS framework will be provided. Possible topics for this project seminar cover the following domains (not limited to):

  • Convolutional Neural Networks for image analysis and transformation*.
  • Integration of interactive rendering techniques in 3rd party applications (e.g., Photoshop plugin).
  • Implementation of interactive image stylization and editing tools for desktop systems.
  • Service-based image and video-processing*
  • Automated video summarization approaches to efficiently and effectively shorten videos*.
  • Web-App development for service-based image- and video processing

Topics marked by a * are related to a joint research project of the Hasso Plattner Institute with Digital Masterpieces and the German Federal Ministry of Education. The research project investigates new concepts and techniques for automatic video abstraction.


  • Successful completion of the lectures Computer Graphics I and/or II
  • Basic knowledge of OpenGL and OpenGL ES Shading Language (GLSL) for image and video processing topics
  • Basic knowledge/understanding of Neural Networks and/or ComputerVision algorithms for image and video analysis topics
  • For Service/WebApps development:
    • Basic knowledge/understanding of Angular, Node.js, Java-Script or Docker
    • Basic knowledge of Web-App development
  • For Android mobile development:
    • Basic knowledge of Java programming language
    • An Android Device supporting OpenGL ES 3.0 or higher is welcome, but not needed.
  • For iOS development:
    • Basic knowledge of Swift development 
    • An Mac or MacBook, as well as an iOS device
  • For Desktop development:
    • Basic knowledge of C++ development 
    • Familiarity with Qt Lib


  • Mednieks et al., Android Programming, O’Reilly (or similar)
  • Joshua Bloch, Effective Java, Online
  • Topic-specific material will be provided throughout the course

Lern- und Lehrformen

Project seminar (4 SWS/6 ECTS)


The final grade will be determined as follows:

  • 50% Documented source code & prototypical application
  • 15% Concept presentation (approx. 10 minutes)
  • 25% Final presentation (ca. 20 minutes)
  • 10 % Projectmanagement


The kick-off meeting will take place on 16.10.2018, 09:15, in A-2.1

The lecture will take place in the first 4 weeks (15.10. - 09.11.2018)

Subsequently, the project part will start in an self-organized way. Appointments with the supervisor are coordinated with the individual supervisors.

The midterm presentation will take place in the week from 10.12.-21.12.2018.

Based on student’s voting, the final presentation will take place February/March 2019.
