The human visual system adapts to changes in white tone of the illumination maintain approximately same object color appearance. Chromatic adaptation transforms (CAT) were developed predict corresponding colors, which are colors that look under a wide range illuminants. However, existing CATs fail accurately particularly colored illumination, because an inaccurate estimation degree adaptation. In this study, impact adapting field size on was investigated. A memory matching experiment...

Current virtual reality (VR) system takes gesture interaction based on camera, handle and touch screen as one of the mainstream methods, which can provide accurate input for it. However, limited by application forms volume devices, these methods cannot extend area to such surfaces walls tables. To address above challenge, we propose AudioGest, a portable, plug-and-play that detects audio signal generated finger tapping sliding surface through set microphone devices without extensive...

Various simulation methods of color appearance for dichromats or anomalous trichromats have been proposed over the years. To further improve performance model and extend application range to both trichromats, we a cone fundamentals specifically designed individuals with red-green type vision deficiency (CVD) based on CIE 2006 physiological observer model. By utilizing simulated fundamentals, it becomes possible predict real scenes digital images CVD. The fundamental premise new is rooted in...

Intrinsic decomposition separates an image into reflectance and shading, which contributes to editing, augmented reality, etc. Despite recent efforts dedicated this field, effectively separating colored illumination from correctly restoring it shading remains challenge. We propose a deep intrinsic method address issue. Specifically, by transforming process in RGB domains the combination of intensity chromaticity domains, we novel macro network framework. This framework enables generation...

This study investigated the discomfort glare caused by LED luminaires. It included three different luminaire structures, under two background luminances, seen at angles above line of sight. Observers scaled using a seven-category scale. The results showed that darker or smaller angle led to more and non-uniform produced than uniform one. Furthermore, Unified Glare Rating was tested data. performed reasonably well, but there is still room improve predictions for

We propose a method to construct compact dual focal-plane optical see-through near-eye display using diffractive waveguides and multiple lenses. A virtual image from device is projected into three-grating waveguide an objective lens, can be shown at far distance with extended eye box. One negative lens employed reduce the focus of image, corresponding positive used compensate for distortion accommodation errors. Thus, not only near achieved, but also plane further generated by introducing...

Whiteness is an important colorimetric characteristic for surface colors. Currently, the CIE whiteness formula widely used to characterize of a in industry, whose limitations have been well documented. In this study, appearance 55 textile samples [43 non-fluorescent whitening agents (FWAs) and 12 FWA samples] were evaluated under six lighting conditions, comprising three levels correlated color temperature (CCT) (i.e., 3000, 4000, 6500 K) two UV radiation zero high), by observers with normal...

This paper proposes a new glare model for assessing discomfort caused by LED luminaires having different luminance uniformities. It has been derived from the rating data groups of representing degrees uniformity. In total, 5040 ratings were collected. Unified Glare Rating was tested using these data. found that under-estimates perception produced non-uniform sources. Furthermore, two modified models proposed Tashiro et al. and present authors tested. They both performed well when predicting results

When the color difference between images perceived by left eye and right exceeds a certain threshold, binocular rivalry could be activated, which is main cause of visual fatigue. This threshold referred to as fusion limit. Past studies on quantitative measurement limit were always performed presenting stimulus (varying in color, disparity, size, etc.) under dark background. To investigate how background luminance contrast influence limit, series forced-choice psychophysical experiments...

Whiteness is an important characteristic for surface colour, which affected by the spectral power distribution of illumination due to fluorescent whitening agents contained in many white objects. The CIE whiteness metric has been widely used but known have limitations. For example, boundary noted not considered large enough, because, cases, a whose chromaticity lies outside can still be perceived as white. Further, only defined characterize under Illuminant D65, and thus it should applied...

Dear editor, This letter presents a user study to explore the effectiveness of gesture interaction in driver assistance system (DAS). Distracted driving is specific form inattention and distraction occurs when drivers' attention diverted from other activities. According report National Highway Traffic Safety Administration [1], distracted responsible for 15% all motor vehicle accidents USA, resulting 3142 traffic fatalities an estimated additional 424 000 people injured motor-vehicle crashes...

Whiteness is an important colorimetric characteristic for surface colors.The CIE whiteness formula, the most widely used only characterizes of a color under standard D65 and requires sample to be within small chromaticity region.In this study, 20 observers evaluated appearance 88 samples four light settings at different CCT levels (i.e., 3000, 4000, 5000, 6500 K).The were carefully selected spectral power distributions designed using spectrally tunable LED device, so that chromaticities each...

In this study, the impact of starting point chromaticity and number observers on memory color matching results was investigated. Matching data were obtained for 3 objects (neutral grey cube, yellow lemon green apple) under a neutral white background illumination. Memory matchings made ten points which eight chromaticities symmetrically distributed along hue circle centered at equal energy (EEW) illumination; one EEW with same as background. The track from to matched also recorded. It did not...

In order to investigate the association between polymorphisms in genes encoding metabolizing enzymes (CYP1A1-MspI, EC-SOD (extracellular superoxide dismutase), GSTT1, GSTM1, ALDH2), cigarette and alcohol consumption, risk of oral squamous cell carcinoma, we conducted a prospective case-control study comprised 750 individuals with carcinoma (OSCC) healthy individuals. Data about smoking drinking habits were collected along other demographic clinical information. Peripheral blood samples for...

The immersive augmented reality (AR) system necessitates precise depth registration between virtual objects and the real scene. Prior studies have emphasized efficacy of surface texture in providing cues to enhance perception across various media, including scene, reality, AR. However, these predominantly focus on black-and-white textures, leaving a gap understanding effectiveness colored textures.To address this further explore texture-related factors AR, series experiments were conducted...

To investigate chromatic adaptation and develop transforms (CATs), many psychophysical experiments have been conducted to collect corresponding colors (CC) under various illumination conditions. Most modern CATs developed based on a database of CC sets collected in the 20th century. More recently, several additional by Smet et al., Wei Ma al. using memory color matching or achromatic methods. The analysis these data indicates that for yellowish (located close Planckian locus) greenish...
