Nam","doi":"10.1117/12.2520266","DOIUrl":"https://doi.org/10.1117/12.2520266","url":null,"abstract":"We have successfully implemented and reported 360-degree viewable tabletop-style holographic display prototype systems. In order to support 360 degree horizontal viewing angle, which is very much wider than previous systems, we used binary amplitude modulating DMD device as SLM of the display system. DMD has higher total data rate due to its high refresh rate, which is denoted as extended SBP or eSBP, than other SLM devices like LCD or LCoS. This is much beneficial for the system design aiming at wider viewing angle or larger image size. However, Binary amplitude modulating hologram has inherent limitation in terms of resulting hologram image quality, and thus there has been lots of studies on quality-improving coding algorithms like BERD or DBS. In this paper, pros and cons of using DMD in holographic display system are discussed, and in-depth analysis and experimental results are presented on the behavior and limitations of the reconstructed image quality based on our prototype system. Image quality is measured with various metrics like 3D-MTF, depth resolution and color reproducing fidelity for different pixel resolutions from QVGA up to 4K UHD. 3D-MTF represents lateral image resolution and depth resolution has to do with degree of supporting accommodation of human vision in holographic displays. Based on these observations, we draw some projection on the required pixel resolutions of binary modulating SLM device for achieving acceptable hologram image quality.","PeriodicalId":350781,"journal":{"name":"Three-Dimensional Imaging, Visualization, and Display 2019","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132006105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of the proposed framework is to compute consistent depth information over the multiple cameras which is hardly achieved by conventional approaches based on the pairwise stereo matching. We first perform stereo matchings on adjacent image pairs using a convolutional neural network-based correspondence scoring model. Once the local disparity maps are estimated, we consolidate the disparity values to make them globally sharable over the multiple views. We finally refine the depth values in the image domain by introducing a novel image segmentation method considering edges in the image to obtain a semantic-aware global depth map. The proposed framework is evaluated on three different real world scenarios, and the experimental results validate that our proposed method produces accurate and consistent depth maps for images captured by the light field camera arrays.","PeriodicalId":350781,"journal":{"name":"Three-Dimensional Imaging, Visualization, and Display 2019","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132124717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A low-cost, compact, 3D-printed shearing interferometer is used to record video holograms of RBCs. Each hologram frame is reconstructed in order to form a spatio-temporal data cube from which features regarding membrane fluctuations are extracted. The motility-based features are combined with static morphology-based cell features and inputted into a random forest classifier which outputs the disease state of the cell with high accuracy.","PeriodicalId":350781,"journal":{"name":"Three-Dimensional Imaging, Visualization, and Display 2019","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115088991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the most interesting medical applications of QPI-DHM is that it can be used to analyze illnesses in which the refractive index or/and the morphology of cells/tissues are distorted, from the acquisition of a single image. In this contribution, we obtain the phase maps of red blood cells (RBCs) samples of patients suffering from diabetes mellitus type 1 (DM1) by using a DHM. Our experimental results show that the measured phase values are significantly different between control non-diabetic and diabetic patients. The high correlation coefficient between the phase and the glycated hemoglobin (HbA1C) values determined by the gold standard method to screen diabetes and the clear separation between the two groups indicate that DHM may potentially be used to evaluate long-term glycemic control in diabetic patients as well as to diagnose diabetes.","PeriodicalId":350781,"journal":{"name":"Three-Dimensional Imaging, Visualization, and Display 2019","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132970060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
