The effect of ambient light source and display type on visual fatigue was investigated. The tested ambient illumination included 120Hz full modulated LED light source, normal fluorescent light source and dark environment. And the tested display type included 2D and 3D based on shutter glasses. Visual fatigue was measured with subjective ratings (12 symptoms, considering general discomfort and eye...
The difference of perceived glare between two different working modes (i.e., computer work and reading/writing) caused by LEDs in office was investigated. Discomfort glare are evaluated in two aspects, the general glare and overhead glare. For general glare study, all the LED luminaires installed in the ceiling of the experimental room were switched on to realize a uniform lighting distribution like...
The impact of ambient illumination on visual fatigue while watching TV was investigated. The tested ambient illumination included 120Hz full modulated LED light source, normal fluorescent light source and dark environment. Visual fatigue was measured with subjective ratings (12 symptoms, considering general discomfort and eye fatigue) and ophthalmological parameters (CFF, NRA, PRA, NPA, NPC) both...
The flexible pinhole camera (FPC) allows flexible modulation of the sampling rate over the field of view. The FPC is defined by a viewpoint and a map specifying the sampling locations on the image plane. The map is constructed from known regions of interest with interactive and automatic approaches. The FPC provides inexpensive 3D projection that allows rendering complex datasets quickly, in feed-forward...
To reduce the loss of visual details in simplification for textured meshes, this paper presents a simplification method based on mesh segmentation. Firstly, the model is partitioned into some sub-meshes according to their properties of appearance, such as texture, normal, etc. Thus, the correlation between sub-meshes can be decreased. Then, we calculate the error metric for the edge collapse in each...
The small color-difference data obtained by printed sample were used to analyze and evaluate the color-difference forecast performance of CAM02-LCD, CAM02-SCD and CAM02-UCS color-difference formulae based on color appearance model, CIECAM02, the result was compared with the evaluation of CIE L*a*b*, CIEDE94, CMC (1:1), CMC (2:1) and CIEDE2000 classical color-difference formulae based on CIE L*a*b*...
The mathematic model of the oil-water two-phase distribution information is established based on double integral infinitesimal principle, an ECT measurement system of 8-electrode oil-water two-phase flow is set up that is comprised of a measurement circuit with stray-capacitance-resistance and a 80C32 SCM, both of which control the measurement among the pole plates and the capture system. The image...
