Gwangju Institute of Science and Technology

With the emerging market of AR/VR imaging products, 3D video has become an active area of research anddevelopment in recent years. 3D video is the key to provide more realistic and immersive perceptual
experiences than the existing 2D counterpart. There are many applications of 3D video, such as 3D movie and
3DTV, which are considered the main drive of the next-generation technical revolution. Stereoscopic display
is the current mainstream technology for 3DTV, while auto-stereoscopic display is a more promising solutionthat requires more research endeavors to resolve the associated technical difficulties.
In this talk, we are going to cover the current state-of-the-art technologies of 3D video capturing andprocessing for immersive AR/VR applications. After defining the basic requirements for 3D realistic
multimedia services, we will cover various multi-modal immersive media processing techniques. We also
address the depth estimation problem for natural 3D scenes and discuss several challenging issues of 3Dvideo capturing and processing, such as camera calibration, image rectification, illumination compensationand color correction.

There are three traditional dancing styles in Sri Lanka called Upcountry dance, Low country dance andSabaragamu dance where those originated from different areas in Sri Lanka.
As the movements of hands and feet is fundamental to any dancing style, in this study, we focus on the handmoving patterns in order to analyze the differences between the three dancing styles. We analyzed the
movement of hands with respect to time using the optical flow method.

Dept. of Electrical Engineering, National Cheng Kung University

In this paper, a low-complexity stereo matching system including image downsizing, prime stereo matching,refinement and depth map upsizing main units is proposed. The prime stereo matching unit jointly uses thecosts of color gradient, color intensity and texture census in downsizing images to reduce the mostcomputation but still keep good quality. The depth upsizing by referring high-resolution images includes
depth value upscaling and selected bilinear interpolation to achieve high-precision and high-resolution depth
map. The evaluations of the proposed algorithms in parts are exhibited to assess the effectiveness of functionsindividually. In comparisons of the existing algorithms, simulation results show that the proposed stereo
matching system performs considerably better in terms accuracy and computation time.

2Magneto-optical spatial light modulators (MOSLM) have been developed for realizing 3D holography whichhas 1000×1000-pixel-format with a pixel pitch of 2 um, and have shown successful display demonstration of
2D images. A pixel comprises two magnetic thin films which can modulate reflected light according tomagnetization direction (Magneto-optical Kerr effect). The direction is controlled by current injection into themagnetic films, which is provided from a transistor backplane. It has potential for downsizing pixel pitch to1um because of its pixel size as small as 0.5 um, which could drastically increase the viewing zone of theholography images.

2K1K (>1080p) LCoS panels with 1% cell gap uniformity error and linearly calibrated Look-Up-Table (LUT)
were evaluated for holographic applications. The PCM-2-01 and PCU-3-01 LCoS panels were able to coverfull 2 π phase modulation at 3.4 and 1.6 ms at 633 nm, respectively. The zero order light leakage and spatiallyanamorphic phenomenon in both horizontal and vertical gratings were suppressed comparing to thecommercial panels. The triangular pyramid image was computed and demonstrated for 3D holography. The
video image captured by high speed camera revealed that the frame switching time corresponding to themeasured results.

In this paper, we tackle the problem of how to sample object depth range to generate hologram efficiently
from it. For this we consider observing hologram reconstructed by SLMs through an eye. The
reconstructed hologram is finally imaged with a finite pixel pitch on the retina plane of an eye. We explorethat the CoC (Circle of Confusion) resulting from the finite sized pixel calls a DoF based, non-uniform
sampling scheme on the 3D object space in combination with depth-adaptive eye focusing, pupil size, andretina plane distance. According to the DoF based sampling scheme, we have quantized input object depth
space into non-equally spaced planes along z-axis which otherwise may be into equally spaced planes if we
adopt a conventional plane based CGH approach. We have simulated and compared the retina images ofhologram generated by both the DoF based sampling scheme and the conventional plane based approach. The
initial simulation results suggest us that 3D data sampling by the proposed DoF based scheme could be agood input for hologram generation of 3D display from the perspective of eye observation.

Phase-modulation type holographic three-dimensional (3D) display has advantages such as the use of fullspace-bandwidth product of the spatial light modulator (SLM) and high energy efficiency by comparing withthe amplitude-modulation type 3D display. Especially, a high speed phase-mode SLM has potentials toenlarge the effective size of SLM and enlarge the viewing zone angle those are two big problems forholographic 3D display. However, there are many problems to be solved. In this presentation, we described
the current status of the 3D display using phase-mode SLM, especially binary phase-mode SLM. Numericaland experimental demonstrations have been provided.

In this research, based on a major goal of holographic head mounted display (HMD) implementation, wedeveloped the small special purpose computer for holography on embedded system. Our system used the
Xilinx ZYNQ MP SoC, system-on-a-chip (SoC) in which an ARM CPU and a field programmable gate array(FPGA) are built in one chip. We succeeded in developing a system that can calculate objects represented by
3,108 points at 15 frames per second (fps). It can be perceived as moving images in one chip size.

In this paper, we try to solve the problem of mismatches when the large-size images are stitched. Because of
the color average, color deviation standard and color luminance in every sub-image is inconsistent. Therefore,
we utilize the Wallis filter algorithm, and avoiding irregularity in image reconstruction to achieve the better
performance in large-size.

In holographic projection, Iterative Fourier transform algorithm (IFTA) is commonly used to generate thecomputer-generated hologram (CGH), and the symmetrical iterative Fourier transform algorithm (SIFTA) is
an improved method to decrease the iteration times. However, using the SIFTA method, the reconstructed
image is blurred on the edge by noise. Based on both SIFTA and IFTA, we present a hybrid iterative Fouriertransform algorithm (HIFTA), which includes restrictions on the area of the target image. In simulation andreconstruction results, the calculation speed has been accelerated by 2 times compared to IFTA and SIFTA
with higher performance of image quality.

We evaluate the readability of visual information on a head-up display using an autostereoscopic display inplace of a virtual image screen. The result suggests that 3D head-up displays offer better readability than theconventional head-up displays. To evaluate the adverse effect caused by the crosstalk, we carry out anexperiment to assess the readability under different crosstalk levels. The result shows that the crosstalk in 3D
head-up displays should be under 7 %. The validity of the proposed method is confirmed with a prototype
HUD hardware system.

An index that can predict the perceptual visibility of color breakup for varying image content is valuable infield sequential color (FSC) displays, whereas the current indices are usually for fixed patterns. To solve thisproblem, we establishment an image database, and performed visual experiments to acquire the subjective
color breakup scores. A theorem that the color breakup perception is mainly determined by the image regionswith visual saliency values higher than a certain threshold, called the dominant visual saliency (DVS) regions,
was proposed and verified.

Dept. of Electrical Engineering, National Cheng Kung University

In this paper, a stereo matching with double refinements which combines centralized texture depth packing(CTDP) system is proposed. In the traditional stereo matching algorithm, left-right check in the refinement
process is unable to detect mismatching errors usefully. In order to raise the accuracy, texture-based detection
is proposed to flag mismatching errors. In addition, the CTDP format which has no corresponding hardware
implementation is proposed, recently. This paper proposed the CTDP system combined with a stereo
matching with double refinements. The design of stereo matching requires 27k logic elements, 30k registers
and 4.8Mb RAM, and the process speed achieves 60 frames per second with the resolution of 1920 × 1080
and 64 disparity levels in 160 MHz. The design of CTDP architecture requires 5 776 logic elements, 7 791
registers and 1.43 Mb RAM, and the process speed achieves 60 frames per second with the resolution of 1920
× 1080.

Augmented Reality (AR) and Mixed Reality (MR) are the next revolution in the way humans will beinteracting with the digital world on a daily basis. In the very near future, Smart glasses will start replacing
the existing "4-screens" we are using today (TV, PC, Tablet, Smartphone). AR/MR breakthrough will be theunique capability to mix digital content with the real world surrounding the user, whether he/she is indoor oroutdoor. For this effect, minimum latency becomes a critical requirement to achieve a good user experienceand 5G will be the first-ever wireless technology making such thing possible.

Cybersickness is one of the most important problems on virtual reality (VR). However, most of recent
research used subjective questionnaire to determine the level of cybersickness, instead of objective bio-signal.
This study uses electroencephalography (EEG) to predict cybersickness level. Results of this study indicate ahigher level of cybersickness caused power of gamma band (>32Hz) stronger and the event-related potential(ERP) P300 amplitude decreased after using VR.

The necessity to use collimation optics is the biggest hurdle in realizing a projection based integral display atlarger scales. In this paper we report a solution by using Digitally Designed Holographic Optical Element(DDHOE). The divergence of the projector beam is compensated by adding necessary functions on the lensarray, by fabricating the lens array as a DDHOE.

visually equivalent light field 3D (VELF3D) displays offer only horizontal parallax due to the RGB stripe
color subpixel structure. Though a special subpixel structure enables full parallax, it is inefficient and not

Multi-view image rectification is one of the important tasks for generating stereoscopic images. Especially,
non-calibrated image rectification could often lead to failure since it depends only on visual feature matching.
Therefore, we propose an efficient and robust image rectification algorithm for non-calibrated multi-view
images. At first, we apply constraints to a matching procedure for eliminating some false matching results.
Next, we find an optimal transformation matrix for each image by repeatedly changing estimation parameterswith geometric constraints. Finally, we elaborate rectified images through shearing correction and disparity
adjustment. We evaluate the rectification results in terms of the rectification error.

cannot record particular images, which are composed of many black pixels (pixel values ‘0’), in the 3D

Research on stereoscopic image quality has become the new trend in recent days. However, the most researchteam are doing effort on assessing the perceptual quality of two-dimensional images or videos. Therefore, we
proposed using structural similarity (SSIM) index to assess stereoscopic images rather than conventional
methods such as peak signal-to-noise ratio (PSNR) and root-mean-squared-error (RMES). The differencewith other conventional methods is that SSIM considers images as perceived change in structural information,
including contrast, luminance and structural terms. The experimental results indicated that the SSIM canassess the fidelity of stereoscopic images more accurately.

2D images. Furthermore, it was arranged as transparent mode when the display offered 3D images. Then thedepth information of 3D images would not be destroyed by the diffuser.

We have proposed and developed two new methods to increase far depth perception in both see-through andclosed HMDs (Head Mounted Displays) by putting far real objects. First method in see-through HMD is toput a real object at father position than 3D image. Second method in closed HMD is to put the display forstimuli at father position than 3D image. By first method in see-through HMD with far real object at 7 m,
perceived depth can be increased over the maximum perceived depth of 4 m in closed HMD without real
object. By second method in closed HMD with far stimuli display at 7 m, perceived depth can successfully
coincide well with far designed depths of 3-6 m.

The durability and load-bearing properties of building decline due to the passage of time. The reason isnatural disasters and weathering, etc. As a sign of it, cracks are generated on the concrete structure surface. In
order to maintain and manage the building, training of workers who inspect cracks is required. We propose asimulator system of inspection with high reality by pasting the image of cracks on the wall using Augmented
Reality(AR). By experimental results, it was confirmed that cracks can be secured to the concrete structuresurface by the proposed method.

The large-aperture hole-patterned liquid crystal (LC) lens was demonstrated with inserted floating multi-ringelectrode (FME), and a high-k layer was layout outside the holepatterned electrode. The used high-k layer
assisted to distribute the electric field throughout the clear aperture, decreased the thickness of the dielectricglass layer between the holepatterned electrode and LC layer and thus reduced the operation voltage of LC
lens. The inserted FME increased the lens power and decreased the wavefront aberration of LC lens.

In this paper, we develop an openGL based viewer to render panoramic photographs from two fish-eye
cameras. To achieve this goal, we summarized the coordinate transformation relationship between wide-view
images and a sphere. According to the conversion from UV texture coordinates to a sphere model, it is readily
to render a textured sphere, as well as 360 photograph, on OpenGL.

Industrial Technology Research InstituteA method is proposed to segment foreground objects for expanding the application of augmented reality. The
method uses a low cost video camera with an optical see-through HMD and all process operates via
horizontal head motion only. Foreground objects are not easy to be segmented in a complex 2D image. Depth
sensor can help. However, it increases cost and weight. Moreover, some depth sensors perform badly in sunnydays. The proposed method doesn’t have these problems and the segmentation results are acceptable.

Preferred 3D locations of text message were investigated psychovisually based on a simulation of an
OST-HMD in various outdoor environments. Statistics of the background image were used to predict theobserver preferred locations. The results show that luminance of the background region plays most importantrole and artificial neural network performs well in the prediction. The virtual distance of the floating text is
2.06 m on average. The preferred distance shows positive correlation to the distance of the behind scene.

Confocal microscopy has been widely used to obtain optical three-dimensional images. However,point-by-point scanning of conventional confocal techniques is time consuming. A variety of confocal
techniques has been developed; however, axial scan is still required to form the entire three-dimensional
images. Here, a non-axial-scanning multifocal confocal microscopy is presented. The proposed system
combines multiplexed volume holographic gratings (MVHGs) in illumination and corresponding confocal
imaging apertures.

Liquid crystal lenticular lens arrays are suitable to be applied to the portable products such as tablets, mobile
phones, and the like for Auto-stereoscopic Display. Because it enables the display panel to switch between 2D
and 3D modes. However, it induces the shielding effect on the function of in-cell touch panel. In order tosolve this issue, we proposed the improved structure and the feasible solution. The way is reducing theelectrode line width to increasing the aperture ratio. The reduction of the electrode line width can ensure thelens quality of the liquid crystal lens for the auto-stereoscopic display and the aperture ratio is increased inorder to make the in-cell capacitive type touch panel be actuated properly.

The purpose of proposed research is to provide a comprehensive cloud service for 3D authoring tool and file
management. Currently, it is still difficult to have a 3D authoring tool. So far, to process a 3D model, such as
slicing, editing, optimization and supporting, is unfriendly for most non-professional users. We develop a
cloud service based on Amazon web service (AWS) to carry out a scenario for 3D file management, storage,
customized 3D printing data and on-line slicing.

Cybersickness is one of the most important problems on virtual reality (VR). However, most of recent
research used subjective questionnaire to determine the level of cybersickness, instead of objective bio-signal.
This study uses electroencephalography (EEG) to predict cybersickness level. Results of this study indicate ahigher level of cybersickness caused power of gamma band (>32Hz) stronger and the event-related potential(ERP) P300 amplitude decreased after using VR.
