Multiple layered abstract data is difficult to visualize on 2D displays, especially when the spatial arrangement of depth needs to be shown. One of the methods used is to remove less important layers to reveal underlying layers [Viola et al. 2005]. Although the layers are revealed, they often appear as painted on a skin outer surface (Figure 1(a)).(More)
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 relies on proprietary and vendor-specific formats which are unsuitable for storage or exchange of such(More)
The performance of video tone-mapping operators is investigated in a rating experiment using two criteria: overall quality and fidelity to real-world experience. The study includes a tone-curve used in commercial cameras, rarely considered in tone-mapping evaluation studies. The quality is measured for a range of parameter settings, revealing the importance(More)
High dynamic range (HDR) images and video contain pixels, which can represent much greater range of colors and brightness levels than that offered by existing, standard dynamic range images. Such “better pixels” greatly improve the overall quality of visual content, making it appear much more realistic and appealing to the audience. HDR is one of the key(More)
H IGH BIT DEPTH data acquisition and manipulation have been largely studied at the academic level in the last 15 years and are rapidly attracting interest at the industrial level. An example of the high interest for High Dynamic Range (HDR) imaging is the use of 32-bit floating point data for video and image acquisition and manipulation that allows a(More)
Visual metrics can play an important role in the evaluation of novel lighting, rendering, and imaging algorithms. Unfortunately, current metrics only work well for narrow intensity ranges, and do not correlate well with experimental data outside these ranges. To address these issues, we propose a visual metric for predicting visibility (discrimination) and(More)
In our paper, we introduced a low energy, high frequency, shift variant component ρ̂ of the light transport function H, that captures cross-screen filter diffraction effects rS present in the captured image. In this section, we derive statistical properties of this function rS which we use in our paper (Equation 9 in the paper). First, we present empirical(More)
