This paper presents a novel and efficient approach to color in high dynamic range (HDR) imaging. In contrast to state-of-theart methods, we propose to move the complete HDR imaging process from RGB to a luminance-chrominance color space. Our aim is to get a computationally efficient technique and to avoid any possible color distortions originating from the three RGB color channels processed sep...

In this paper we present a tone mapping operator (TMO) for High Dynamic Range images, inspired by human visual system adaptive mechanisms. The proposed TMO is able to perform color constancy without a priori information about the scene. This is a consequence of its HVS inspiration. In our humble opinion, color constancy is very useful in TMO since we assume that it is preferable to look at an i...

Tone mapping algorithms should be informed by accurate color appearance models (CAM) in order that the perceptual fidelity of the rendering is maintained by the tone mapping transformations. Current tone mapping techniques, however, suffer from a lack of good color appearance models for mesopic conditions. There are only a few currently available appearance models suited to the mesopic range, n...

The present paper discusses the concept of subtractive color mixing widely used in color hardcopy applications and shows that a more realistic concept would be “spectral mixing”: the physical description of the coloration of light by printed surfaces comes from the mixing of light components selectively absorbed by inks or dyes during their patch within the printing materials. Some classical re...

The stabilization of a single color tone reproduction curve (TRC) is critical for high delity color printing. A TRC controller uses a small number of actua-tors and a small number of measurements to stabilize the potentially high dimensional TRC. The overall least squares deviation of the TRC from the ideal nominal TRC is minimized in the face of the many disturbances and uncertainty in the sys...

Videos captured by consumer cameras often exhibit temporal variations in color and tone that are caused by camera autoadjustments like white-balance and exposure. When such videos are sub-sampled to play fast-forward, as in the increasingly popular forms of timelapse and hyperlapse videos, these temporal variations are exacerbated and appear as visually disturbing high frequency flickering. Pre...

In the ceramic industry half-tone images are often generated from a small number of separations with the result that inks are printed over each other to achieve the final print. This study investigates whether an n-modified spectral Neugebauer-based model, which has been used quite successfully to predict reflectance for prints on paper substrates, can be used to predict the color of half-tone ...
