Full-parallax immersive 3D display from depth-map cameras

2016

We exploit two different versions of the Kinect to make comparison of three-dimensional (3D) scenes displayed by proposed integral imaging (InI) display system. We attempt to show the difference between each version specifications and capacity. Furthermore, we illustrate our study result with some empirical imaging experiment in which the final result are displayed with full-parallax. Each demonstrated integral images can provide clear comparison results to the observer.

Full parallax three-dimensional display from Kinect v1 and v2

2016

We exploit the two different versions of Kinect, v1 and v2, for the calculation of microimages projected onto integral-imaging displays. Our approach is based on composing a three-dimensional (3-D) point cloud from a captured depth map and RGB information. These fused 3-D maps permit to generate an integral image after projecting the information through a virtual pinhole array. In our analysis, we take into account that each of the Kinect devices has its own inherent capacities and individualities. We illustrate our analysis with some imaging experiments, provide the distinctive differences between the two Kinect devices, and finally conclude that Kinect v2 allows the display of 3-D images …

Optimized integral imaging display by global pixel mapping

2006

Integral imaging systems are imaging devices that provide 3D images of 3D objects. When integral imaging systems work in their standard configuration the provided reconstructed images are pseudoscopic; that is, are reversed in depth. In this paper we present a technique for formation of real, undistorted, orthoscopic integral images by direct pickup. The technique is based on a global mapping of pixels of an elemental-images set. Simulated imaging experiments are presented.

Full-parallax 3D display from the hole-filtered depth information

2015

In this paper we introduce an efficient hole-filling algorithm for synthetic generation of microimages that are displayed on an integral imaging monitor. We apply the joint bilateral filter and the median filter to the captured depth map. We introduce in any step of the iterative algorithm with the data from a new Kinect capture. As a result, this algorithm can improve the quality of the depth maps and remove unmeasured depth holes effectively. This refined depth information enables to create a tidy integral image, which can be projected into an integral imaging monitor. In this way the monitor can display 3D images with continuous views, full parallax and abundant 3D reconstructed scene fo…

MMGBSA As a Tool To Understand the Binding Affinities of Filamin–Peptide Interactions

2013

Filamins (FLN) are large dimeric proteins that cross-link actin and work as important scaffolds in human cells. FLNs consist of an N-terminal actin-binding domain followed by 24 immunoglobulin-like domains (FLN1-24). FLN domains are divided into four subgroups based on their amino acid sequences. One of these subgroups, including domains 4, 9, 12, 17, 19, 21, and 23, shares a similar ligand-binding site between the β strands C and D. Several proteins, such as integrins β2 and β7, glycoprotein Ibα (GPIbα), and migfilin, have been shown to bind to this site. Here, we computationally estimated the binding free energies of filamin A (FLNa) subunits with bound peptides using the molecular mechan…

Concurrent TMS-fMRI for causal network perturbation and proof of target engagement

2021

The experimental manipulation of neural activity by neurostimulation techniques overcomes the inherent limitations of correlative recordings, enabling the researcher to investigate causal brain-behavior relationships. But only when stimulation and recordings are combined, the direct impact of the stimulation on neural activity can be evaluated. In humans, this can be achieved non-invasively through the concurrent combination of transcranial magnetic stimulation (TMS) with functional magnetic resonance imaging (fMRI). Concurrent TMS-fMRI allows the assessment of the neurovascular responses evoked by TMS with excellent spatial resolution and full-brain coverage. This enables the functional ma…

Internal Test Sets Studies in a Group of Antimalarials

2006

Topological indices have been applied to build QSAR models for a set of 20 an- timalarial cyclic peroxy cetals. In order to evalua te the reliability of the proposed linear models leave-n-out and Internal Test Sets (ITS) approaches have b een considered. The pro- posed procedure resulted in a robust and consensued prediction equation and here it is shown why it is superior to the employed standard c ross-validation algorithms involving multilinear regression models.

Internet ohjauksessa vai ohjaus internetissä? : ohjaajien käsityksiä internetin merkityksestä työvälineenä

2006

Sekä kansainvälisessä että kansallisessa koulutus- ja työvoimapolitiikassa on viime vuosina korostettu nuorille ja aikuisille suunnattujen ohjaus- ja neuvontapalvelujen saatavuutta, laadun varmistamista ja palvelumuotojen monipuolistamista. Yksittäisten eri elämänvaiheisiin sijoittuvien valintatilanteiden tarkastelun sijasta ohjauksen tavoitteita ja palveluja tulee jäsentää elinikäisen ohjauksen näkökulmasta. Laadukkaat ja kattavat ohjauspalvelut edesauttavat myös taloudellista kehitystä. Perinteisten ohjaajan ja asiakkaan kahdenkeskiseen vuorovaikutukseen perustuvien työmuotojen rinnalle on kehitetty uusia innovatiivisia työmuotoja. Tuoreimpia innovaatioita ovat tieto- ja viestintäteknolog…

mGluR2/3 agonist LY379268, by enhancing the production of GDNF, induces a time-related phosphorylation of RET receptor and intracellular signaling Er…

2011

In the present study we aimed to verify if the enhancement of glial cell line-derived neurotrophic factor (GDNF) production in mouse striatum following treatment with LY379268 may also induce in the nigrostriatal system a time-related activation of RET receptor and its specific intracellular signaling. For this purpose, we have investigated the effects of LY379268 treatment on RET phosphorylation at the Tyr1062 and on downstream signaling Erk1/2, Akt and PLCγ1 pathway activation. The results showed that treatment with LY379268 (3 mg/kg) induces a significant increase of GDNF levels and time-related RET and Erk1/2 phosphorylation in the striatum. These increases were detected at 24 h and 48 …
