The effects of molecular diffusion in spatially encoded magnetic resonance imaging

Geoffrey Bodenhausen, Sina Marhabaie

In spatially encoded MRI, the signal is acquired sequentially for different coordinates. In particular for single-scan acquisitions in inhomogeneous fields, spatially encoded methods improve the image quality compared to traditional k-space encoding. Previ ...

Overview and Evaluation of the JPEG XT HDR Image Compression Standard

Touradj Ebrahimi, Philippe Hanhart

Standards play an important role in providing a common set of specifications and allowing inter-operability between devices and systems. Until recently, no standard for High Dynamic Range (HDR) image coding had been adopted by the market, and HDR imaging r ...

Rate-Distortion Evaluation for Two-Layer Coding Systems

Touradj Ebrahimi, Philippe Hanhart

The Bjontegaard model is widely used to calculate the compression efficiency between different codecs. However, this model is not sufficient to investigate the impact on quality of the interaction of the base and enhancement layer bit rates when comparing ...

Impact of Ultra High Definition on Visual Attention

Touradj Ebrahimi, Philippe Hanhart, Hiromi Nemoto

Ultra high definition (UHD) TV is rapidly replacing high definition (HD) TV but little is known of its effects on human visual attention. However, a clear understanding of this effect is important, since accurate models, evaluation methodologies, and metri ...

Subjective evaluation of HEVC intra coding for still image compression

Touradj Ebrahimi, Philippe Hanhart, Martin Rerabek

High Efficiency Video Coding (HEVC) demonstrates a significant improvement in compression efficiency compared to H.264/MPEG-4 AVC, especially for video with resolution beyond HD, such as 4K UHDTV. One advantage of HEVC is the improved intra coding of video ...

JPEG backward compatible format for 3D content representation

Touradj Ebrahimi, Philippe Hanhart, Martin Rerabek

Different formats and compression algorithms have been proposed for 3D video content, but 3D images are still mostly represented as a stereo pair only. However, for enhanced 3D rendering capabilities, such as depth perception adjustment or display size ada ...
