“…In our experiments, we use two HDR images provided by Laurence Meylan to verify the performance of DABTM. Nine algorithms are considered: Drago [23], Fattal [14], Pattanaik [24], Reinhard02 [12], Reinhard05 [17], Meylan06 [25], Meylan07 [26], Yuanzhen Li [27], single anchor based algorithm and the proposed algorithm DABTM. These algorithms can give visually pleasing results in making detail visible in both the bright and dark regions.…”

SUMMARYIn this paper, we present a Double-Anchoring Based Tone Mapping (DABTM) algorithm for displaying high dynamic range (HDR) images. First, two anchoring values are obtained using the doubleanchoring theory. Second, we use the two values to formulate the compressing operator, which can achieve the aim of tone mapping directly. A new method based on accelerated K-means for the decomposition of HDR images into groups (frameworks) is proposed. Most importantly, a group of piecewise-overlap linear functions is put forward to define the belongingness of pixels to their locating frameworks. Experiments show that our algorithm is capable of achieving dynamic range compression, while preserving fine details and avoiding common artifacts such as gradient reversals, halos, or loss of local contrast.

“…Local tone mapping algorithms [4,5,8,18,16,21,22] work by reducing the gradient magnitude in the areas of high gradient while preserving the areas of low gradient. The human visual system is insensitive to absolute brightness but responds to local contrast, meaning that global differences in brightness can be reduced so long as the darker parts of the image remain darker and the brighter parts remain brighter.…”

Abstract. This paper introduces a process where fusion features assist matching scale invariant feature transform (SIFT) image features from high contrast scenes. FAW defines the order for extracting features: features, alignment then weighting. The process uses three quality measures to select features from a series of differently exposed images and select a subset of the features in favour of those areas that are defined as well exposed from the different images. The results show an advantage in using these features over features extracted from the common alternative techniques of exposure fusion and tone mapping which extract the features as AWF; alignment, weighting then features. This paper also shows that the process allows for a more robust response when using misaligned or stereoscopic image sets.

“…For HDR scenes that have a dynamic luminance range beyond what the conventional display can show, the method of tone reproduction can be used to compress the luminance range to a level that is displayable (Reinhard et al, 2010). While many tone-reproduction methods are available, this study used photoreceptor tone reproduction as it is perceptually based (Reinhard and Devlin, 2005).…”

Investigation of Computer-Simulated Visual Realism for Envisioning the Illusory Visual Effect of Installation Art Using Depth Reversal

Depth reversal is the false perception whereby a receding or projecting spatial composition actually appears as the opposite of that composition. Such illusory effects are often forceful and have become a popular visual effect utilized in many site-specific installation artworks. However, the design approach most often employed is based on trial and error because the visual perception of depth-reversal illusion is often difficult to predict without actually seeing it in reality. Unfortunately, this approach demands extensive time and effort as well as increased material costs. Computer-aided design often provides a low-cost alternative for the design process; however, the feasibility of using a computer simulation in the design process depends upon the visual realism offered by the simulation. This study investigated the visual realism of a computer simulation with regard to envisioning the visual illusion of depth reversal. Perceptual studies were conducted to measure critical distances that occur when an observer experiences the visual perception of depth reversal in both physical and computer-simulated environments. The quantitative experimental results were used to establish the reliability of computer simulation for the design process of installation art that utilizes illusory visual effects of depth reversal from design ideation to exhibition planning.
