High Dynamic Range Imaging and Video Research
High dynamic range imaging (HDRI) is a set of techniques that allows a greater dynamic range of luminances between bright and dark regions of a scene than normal imaging techniques.The intention of HDRI is to accurately represent the wide range of intensity levels found in real scenes ranging from direct sunlight to shadows.
The research focus of this project is on:
- Develop novel tone mapping methods for both HDR images and videos
- Develop novel hardware for HDR display
- Develop novel encoding/decoding methods for HDR images and videos
- Develop novel HDR applications
Tone Mapping Operators Evaluation Research
Tone Mapping Operators (TMOs) is a series of algorithms which “map” HDR images to Low Dynamic Range (LDR) images so that they can be displayed on LDR devices (such as CRT and LCD). Since 1991, many TMOs have been developed. But their quality for different kinds of usages is still not well confirmed.
We are now focusing on doing an psychophysical experiment to confirm TMOs' validity and usability.
