GPU-accelerated integral imaging and full-parallax 3D display using stereo–plenoptic camera system
摘要： In this paper, we propose a novel approach to produce integral images ready to be displayed onto an integral-imaging monitor. Our main contribution is the use of commercial plenoptic camera, which is arranged in a stereo configuration. Our proposed set-up is able to record the radiance, spatial and angular, information simultaneously in each different stereo position. We illustrate our contribution by composing the point cloud from a pair of captured plenoptic images, and generate an integral image from the properly registered 3D information. We have exploited the graphics processing unit (GPU) acceleration in order to enhance the integral-image computation speed and efficiency. We present our approach with imaging experiments that demonstrate the improved quality of integral image. After the projection of such integral image onto the proposed monitor, 3D scenes are displayed with full-parallax.

Effective orthoscopic integral imaging reconstruction via adjustable depth position
摘要： In this paper, we propose an effective orthoscopic three-dimensional reconstruction via adjustable depth position in integral imaging system. Compared to conventional integral imaging reconstruction method, the proposed method can directly reconstruct orthoscopic 3D images through one-step ray tracing with adjustable depth positions. Thus, a real, undistorted, orthoscopic three-dimensional images can be reconstructed various distances without the magnification and overlap process of conventional integral imaging reconstruction. To show the feasibility of the proposed method, the preliminary experiments are carried out and the some experimental results are presented.

Resolution-Enhancement for an Integral Imaging Microscopy Using Deep Learning
摘要： A novel resolution-enhancement method for an integral imaging microscopy that applies interpolation and deep learning is proposed, and the complete system with both hardware and software components is implemented. The resolution of the captured elemental image array is increased by generating intermediate-view elemental images between each neighboring elemental image, and an orthographic-view visualization of the specimen is reconstructed. Then, a deep learning algorithm is used to generate maximum possible resolution for each reconstructed directional-view image with improved quality. Since a pre-trained model is applied, the proposed system processes the images directly without data training. The experimental results indicate that the proposed system produces resolution-enhanced directional-view images, and quantitative evaluation methods for reconstructed images such as the peak signal-to-noise ratio and the power spectral density confirm that the proposed system provides improvements in image quality.

[IEEE 2019 IEEE International Conference on Image Processing (ICIP) - Taipei, Taiwan (2019.9.22-2019.9.25)] 2019 IEEE International Conference on Image Processing (ICIP) - Glasses-Free Led Holoscopic 3D Wall with Effective Pixel Mapping
摘要： Autostereoscopic 3D display technology provides a perception of natural 3D effects without requiring viewers to wear any headgear device. In particular, Holoscopic 3D display mimics fly’s eye using a microlens array in order to reconstruct a real scene in the 3D space and offers a fatigue-free viewing experience. To date, holoscopic 3D displays have been developed based on LCD technology. In this paper, we propose a LED holoscopic 3D wall-size display with effective pixel mapping and microlens parameters which deliver a long-distance 3D viewing experience. Due to the growing popularity of large LED displays, the proposed technology has significant potential for deployment in the advertisement and entertainment sectors.

True colors restoring of reconstructed image in naked-eye 3D LED display based on eliminating optical dispersion
摘要： True colors restoring of reconstructed image in naked-eye 3D LED display based on eliminating optical dispersion. Naked-eye 3D LED display is getting more mature with the increase of LED screen density. And the true colors restoring of reconstructed image in integral imaging LED display is a new direction of the research. Herein, when using the micro lens array to perform the white light, 3D integral imaging LED display has serious optical dispersion. We proposed a kind of optical array model in order to eliminate optical dispersion and restore true colors of the reconstructed image. This model can effectively reduce the chromatic aberration and the crosstalk among the lights by decreasing the large divergence angle of LED’s single pixel point. Besides, the resolution of the reconstructed image can be improved simultaneously. Experimental results validated that compared with previous models, the current model can provide effective reduction of dispersion in LED integral imaging, and further analysis verified the feasibility of the proposed method.

摘要： We introduce AnyLight, a novel programmable lighting device that can mimic the illumination effects of a broad range of light sources —both real and imagined—using the principle of integral imaging. The ?at, panel-shaped device functions in essence as a type of light ?eld display, relying on custom, 3D printed optics to precisely control light rays emanating from each point on its surface, simulating the existence of arbitrary light sources concealed within the device, e.g., spotlight, candle, skylight, etc. A room illuminated with AnyLight would allow occupants to manipulate ambient lighting with a degree of freedom unreachable using existing programmable lighting setups, where typically color is the only adjustable parameter.

High-quality direct-view display combining multiple integral 3D images
摘要： This paper proposes a method for combining multiple integral three-dimensional (3D) images using direct‐view displays to obtain high‐quality results. A multi‐image combining optical system (MICOS) is used to enlarge and combine multiple integral 3D images without gaps. An optical design with a simple lens configuration that does not require a diffuser plate prevents the deterioration in resolution resulting from lens arrangement errors and the diffuser plate. An experiment was performed to compare a previously developed method with the proposed method, and the latter showed a significant improvement in image quality. A method for expanding the effective viewing angle of the proposed optical design was also developed, and its effectiveness was confirmed experimentally. A prototype device of the proposed optical design was constructed using a high‐density organic light‐emitting diode (OLED) panel with 8K resolution and 1058 ppi pixel density to achieve 311 (H) × 175 (V) elemental images, a viewing angle of 20.6° in both the horizontal and vertical directions, and a display size of 9.1 in. In addition, the proposed optical design enabled making device considerably thinner, ie, with a thickness of only 47 mm.

Resolution-enhanced holographic stereogram based on integral imaging using moving array lenslet technique
摘要： We proposed a resolution-enhanced integral imaging (II) based holographic stereogram (HS) using the moving array lenslet technique (MALT). The HS can be generated fast by Fourier transforming the elemental images of II into hogels. However, the low sampling rate of II is inherited in HS. The MALT was introduced to increase the sampling rate of II-based HS. Multiple elemental image array sequences are captured with MALT and transformed to the corresponding HS sequences. All the HS sequences are shifted depending on the movement of the lens array and added together to synthesize the HS with a high sampling rate. The synthesized HS can reconstruct the 3D image with the combined light fields of all the HS sequences. The 3D image quality improvement was verified in numerical and optical reconstruction. Superior to the MALT in II, this method does not need the time-multiplexing technique in the display stage because different HS sequences are displayed in one hologram pattern simultaneously.

摘要： We present an accurate model of integral imaging display based on wave optics. The model enables accurate characterization of the display through simulated perceived images by the human visual system. Thus, it is useful to investigate the capabilities of the display in terms of various quality factors such as depth of field and resolution, as well as delivering visual cues such as focus. Furthermore, due to the adopted wave optics formalism, simulation and analysis of more advanced techniques such as wavefront coding for increased depth of field are also possible.
