Abstract [en]

This report is about how HDR (HighDynamicRange) can be created and used in combination with Tone mapping. This work has been carried out together with Kapsch TrafficCom AB in Jönköping.

The objective of this project is to:

  • Evaluate and investigate the effects given to pictures by HDR and tone mapping.
  • Evaluate if the technology may lead to improvements in Kapsch’s systems.
  • To construct a program which is able to handle some form of tone mapping or HDR-algorithm.

These questions will be answered in this report:

  • What kind of effects has HDR and tone mapping-algorithms on pictures?
  • Can the HDR-technology give better data in Kapsch’s systems?

The research method used in this report is called action research. This means the authors has investigated the technology by reading different documentations and by testing different algorithms to see what kind of result they give. The report describes some of the tests made to see if the technology is appropriate in Kapsch’s system.There is two smaller reports made by the authors which documenting some of the work.The first report describes the work with different settings for a camera to create pictures with HDR-quality. The second report describes the differences between tone mapping-algorithms and different file format. Both reports are included as appendices to this report.In the program created by the authors some larger library’s with standard functions for opening of JPEG-pictures was used. The chosen library’s was MFC and GDI+. The program is developed for a windows environment and handles functions like sharpening with unsharp mask, colour space conversion and tone mapping.
