Chromatic coordinates in HDR image coding

SPIE Proceedings, 2008
The paper presents an undertaking to develop most compact high dynamic range image compression format and shows that chromatic color coordinate system plays a central role in such development. Important design considerations, such as conditions and criterions of data accuracy, efficiency and characteristics of color space, are addressed along the way ...

Tuning Retinex for HDR Images Visualization

Conference on Colour in Graphics, Imaging, and Vision, 2004
In some cases, consumer devices (monitors, printers, cameras, etc) do not allow us to capture or reproduce the full range of luminance information of a synthetic or real scene. Many techniques have been proposed in the last years, that address the tone mapping problem (i.e.

Glare‐limited appearances in HDR images

Journal of the Society for Information Display, 2009
Abstract— Intraocular glare and simultaneous contrast control appearance in high‐dynamic‐range (HDR) images. This paper describes unique test targets that simulate real images. These targets change the HDR range by 500 times, without significantly changing the veiling glare on the retina.

Viewpoint adaptive display of HDR images

2017 IEEE International Conference on Image Processing (ICIP), 2017
In this paper viewpoint adaptive display of HDR images incorporating the effects of ambient light is presented and evaluated. LED backlight displays may render HDR images, but while at a global scale a high dynamic range may be achieved, locally the contrast is limited by the leakage of light through the LC elements of the display.

Evaluating deghosting algorithms for HDR images

2014 22nd Signal Processing and Communications Applications Conference (SIU), 2014
The real world encompasses a high range of luminances. In order to capture and represent this range correctly, High Dynamic Range (HDR) imaging techniques are introduced. Some of these techniques are based on constructing an HDR image from several Low Dynamic Range (LDR) images with different exposures. In the capture and reconstruction phases, the HDR

On-chip compression for HDR image sensors

2010 Conference on Design and Architectures for Signal and Image Processing (DASIP), 2010
An image compressing technique for High Dynamic Range (HDR) image sensors is introduced. Compression is performed in two steps: Pixel value coding optimization followed by DCT-based (Discrete Cosine Transform) compression. A floating point coding technique is first used with a common exponent shared between pixels of the same block, and then a DCT is ...
