Existing computational holographic displays often suffer from limited reconstruction image quality mainly due to ill-conditioned optics hardware and hologram generation software. In this Letter, we develop an end-to-end hardware-in-the-loop approach toward high-quality for displays. Unlike other methods using ideal wave propagation, ours can reduce artifacts introduced by both the light propagation model setup, in particular non-uniform illumination. Experimental results reveal that,...

With the rapid advance of three-dimensional (3D) confocal imaging technology, more and 3D cellular images will be available. Segmentation intact cells is a critical task in automated image analysis quantification microscopic images. One major complications automatic segmentation arises due to fact that are often closely clustered. Several algorithms proposed for segmenting cell clusters but most them 2D based. In other words, these designed segment from single image. Given methods developed,...

Abstract Recent advances in high‐resolution imaging have provided valuable novel insights into structural relationships within cells and tissues both vitro vivo. An analysis of this kind is regularly done by optical sectioning using either confocal or deconvolution microscopy. However, the reconstruction 3D images suffers from light scattering absorption with increasing depth finite transparency used media. Photobleaching fluorochromes has been especially troublesome often only remedy for...

Holography represents an enabling technology for next-generation virtual and augmented reality systems. However, it remains challenging to achieve both wide field of view large eyebox at the same time holographic near-eye displays, mainly due essential étendue limitation existing hardware. In this work, we present approach expanding displays without compromising their underlying view. This is achieved by utilizing a compact 2D steering mirror deliver angular-steering illumination beams onto...

Cardiac circulation is traditionally difficult for students from both high school and colleges to learn biology due its complexity dynamic process. Cadavers can be used as a good tool cardiovascular system. Unfortunately, this approach comes with some major concerns because of the collapsed anatomic structures, no blood flowing. Also cadavers are normally available only in medical schools. Human subjects especially cardiac patients ideal human perspectives structures functions. This,...

Summary In recent years, cell biologists have benefited greatly from using confocal microscopy to study intracellular organelles. For high‐level image analysis, 3D boundary extraction of structure is a preliminary requisite in cellular imaging. To detect the object boundaries, most investigators used gradient/Laplacian operator as principal tool. this paper we propose higher order statistics (HOS) based algorithm for data set kurtosis. After initial pre‐processing, kurtosis map estimated...
