Trapalyzer: A computer program for quantitative analyses in fluorescent live-imaging studies of Neutrophil Extracellular Trap formation.
<p>This data set contains a set of fluorescent microscopy images of a co-culture of neutrophil cells and E. coli bacteria used to study the Neutrophil Extracellular Trap (NET) formation stimulated by bacteria. </p> <p>NETs and live cells were visualized with a double fluorescent staining of DNA using Hoechst 33342 and SYTOX Green. </p> <p><strong>Reagents.</strong></p> <p>Roswell Park Memorial Institute (RPMI) 1640 medium, HEPES, SYTOX<sup>TM</sup> Green, and Hoechst 33342 were purchased from Thermo Fisher Scientific (Waltham, USA). LB broth was purchased from Sigma Aldrich (St Louis, MO, USA).</p> <p><strong>Preparation of blood neutrophils.</strong></p> <p>Neutrophils were obtained from peripheral blood of one healthy blood donor. Blood sample was purchased at Local Blood Donation Centre and according to local regulations, the blood donor enabled blood donation center to sell their blood samples for scientific purposes and the consent of bioethical committee was not required. Blood was collected into a citrate tube and processed within 2 hours from collection. Neutrophils were isolated using density gradient centrifugation followed by polyvinyl alcohol sedimentation, exactly as described in [1]. Isolated neutrophils were suspended in RPMI 1640 medium with 10 mM HEPES (RH). </p> <p><strong>Preparation of bacteria.</strong></p> <p><em>Escherichia coli</em> (American Type Culture Collection(ATCC) 25922 strain) were grown overnight in LB broth with shaking. In the morning, an aliquot of bacterial culture was taken, diluted 100 x in a fresh LB medium and grown for subsequent 2-3 hours. Subsequently, bacterial cultures were washed and resuspended in RH medium.</p> <p><strong>Co-culture of neutrophils with bacteria</strong><br> Neutrophils were seeded into the wells of 48-well plates at the density of 2 ⨉ 10<sup>4</sup> cells/well and allowed to settle for 30 minutes at 37°C, 5% CO2. Subsequently, <em>E. coli</em> was added into the appropriate wells at the multiplicity of infection of 4 or 1 (<em>E.coli</em>: neutrophil). Neutrophils incubated without bacteria were used as a control group. A technical duplicate for each condition was prepared. <br> For each intended timepoint (t=0, 60, 90, 120, 180 minutes), a separate 48 well plate was prepared. The plates were centrifuged for 5 minutes at 250 g to allow the contact of bacteria with neutrophils. The plates were incubated at 37°C, 5\% CO2 for a specified time and then the samples were stained with SYTOX<sup>TM</sup> Green (100 nM) and Hoechst 33342 (1.25 μM) for 10 minutes. Four images of each well were taken with Leica DMi8 fluorescent microscope equipped with a 10× magnification objective (Leica, Wetzlar, Germany). Overall, 120 images have been obtained.</p> <p> </p> <p><strong>2019_04_24--ecoli_neu_tiff_channel_merged.zip:</strong> Images in .tif format, each containing 5 channels: channel 1 for SYTOX Green fluorescent stain (green fluorescence), channel 2 for Hoechst 33342 fluorescent stain (blue fluorescence), and three channels for transmission light encoded in RGB values. </p> <p> </p> <p><strong>2019_04_24--ecoli_neu_tiff_raw_exported.zip:</strong> Images split by different light sources: transmission light (_ch00.tif), SYTOX Green fluorescence (_ch01.tif), Hoechst 33342 fluorescence (_ch02.tif).</p> <p> </p> <p>[1] Bystrzycka W, Moskalik A, Sieczkowska S, Manda-Handzlik A, Demkow U, Ciepiela O.

X-ray computed microtomographic (XRCT) images of a fault core that slipped during the 1726 San Andreas faultzone earthquake
<p>Uploaded are x-ray computed microtomographic (XRCT) images used to examine solid-fluid interactions within one of the near-surface fault cores that slipped during a circa (ca.) 1726 San Andreas Fault zone earthquake. The study site is 16 km northwest of Bombay Beach, California (33.45873, -115.8560), and our sample, collected at a depth of 1.2 m below sea level, is from a trench that exposes deposits of ancient Lake Cahuilla. The ca. 1726 earthquake occurred during a highstand of ancient Lake Cahuilla; our study site was ~55 m below the lake's surface at the time. Crustal deformation caused by the ca. 1726 earthquake has been documented for at least 85 km along the southernmost San Andreas fault zone, which has been used, alongside other observations, to constrain the earthquake's size to a magnitude 7.2 or larger with offsets on the order of ~3 m. Since the ca. 1726 earthquake, creep and triggered slip have occurred along the section of the fault we study, with estimates of ~3 mm/yr of motion over the last ~160 years.</p> <p>We acquire XRCT images at the Advanced Light Source, Lawrence Berkeley National Lab, on beamline 8.3.2. Imaging uses a 50 mm LuAG scintillator, PCO Edge camera, and 1X Nikon lens. We image with white light x-rays, 13 ms exposure times, and 2625 projections through 180-degree continuous sample rotations. This produces 1280 two-dimensional image slices with voxels' linear dimensions of 3.24 microns. We reconstruct images and perform ring removal, center of rotation optimizations, and outlier removal using TomoPy. We name the sample FT_50_4_ZZZZ, where ZZZZ represents the image slice number; increasing numbers represent increasing distance into the outcrop.</p>

Computer-rendered HDR and LDR 4k images database
<p>Realistic image computation mimics the natural process of acquiring pictures by simulating the physical interactions of light between all the objects, lights and cameras lying within a modelled 3D scene. This process is known as global illumination and was formalised by Kajiya with the following rendering Equation:<br> <span class="math-tex">\(\begin{equation} \label{eq:rendering_equation} L_o(x, \omega_o) = {L_e(x, \omega_o)} + \int_{\Omega}^{} {L_i(x, \omega_i)} \cdot f_r(x, \omega_i \rightarrow \omega_o) \cdot \cos \theta_i d\omega_i \end{equation}\)</span></p> <p>where:</p> <ul> <li> <span class="math-tex">\(L_o(x, \omega_o)\)</span> is the luminance traveling from point <span class="math-tex">\(x\)</span> in direction <span class="math-tex">\(\omega_o\)</span>;</li> <li><span class="math-tex">\(L_e(x, \omega_o)\)</span> is point <span class="math-tex">\(x\)</span> emitted luminance (it is null if point x does not lie on a ligth source surface);</li> <li>the integral represents the set of luminances <span class="math-tex">\(L_i\)</span>incident in <span class="math-tex">\(x \)</span> from the hemisphere of the directions <span class="math-tex">\(\Omega\)</span> and reflected in the direction <span class="math-tex">\(\omega_o\)</span>. The reflected luminances are weighted by the materials reflecting properties (bidirectionnal reflectance function <span class="math-tex">\(f_r(x, \omega_i \rightarrow \omega_o)\)</span>) and the cosinus of the incident angle.</li> </ul> <p>This equation cannot be analytically solved and Monte Carlo approaches are generally used to estimate the value of the pixels of the final image.</p> <p>This proposed dataset is composed of 32 points of view of photo realistics images with different level of samples (following the Monte Carlo approach) for each. Each image is 3840 × 2160 pixels in size. The most noisy image is of 2⁰ samples and the reference one (the most converged image obtained) is of 2²⁰ samples.

Four-dimensional computational ultrasound imaging of brain hemodynamics
<p><span>Four-dimensional ultrasound imaging of complex biological systems such as the brain is technically challenging because of the spatiotemporal sampling requirements. We present computational ultrasound imaging (cUSi), an imaging method that uses complex ultrasound fields that can be generated with simple hardware and a physical wave prediction model to alleviate the sampling constraints. cUSi allows for high-resolution four-dimensional imaging of brain haemodynamics in awake and anesthetized mice.</span></p>

Computer Vision-Based Image Analysis
<p>Computer Vision-Based Image Analysis Tool is an innovative tool analysing the colour change of the foods in the fridge to correlate this information to the food loss and waste at household level. This tool deals with colour measurement from the 2D image of 3D fresh fruit and vegetable. The system takes the pictures of the selected fruit or vegetable, analyses the image and detects the colour-based deterioration, if any. The deterioration is calculated as area percentage. Finally, this information is correlated to the weight of these fruits or vegetables. This technology will also be adapted to the meat supply chain to evaluate the meat quality according to their colour for further processing.</p>

Low-dose Computed Tomography Perceptual Image Quality Assessment Grand Challenge Dataset (MICCAI 2023)
<p>Image quality assessment (IQA) is extremely important in computed tomography (CT) imaging, since it facilitates the optimization of radiation dose and the development of novel algorithms in medical imaging, such as restoration. In addition, since an excessive dose of radiation can cause harmful effects in patients, generating high- quality images from low-dose images is a popular topic in the medical domain. However, even though peak signal-to-noise ratio (PSNR) and structural similarity index measure (SSIM) are the most widely used evaluation metrics for these algorithms, their correlation with radiologists’ opinion of the image quality has been proven to be insufficient in previous studies, since they calculate the image score based on numeric pixel values (1-3). In addition, the need for pristine reference images to calculate these metrics makes them ineffective in real clinical environments, considering that pristine, high-quality images are often impossible to obtain due to the risk posed to patients as a result of radiation dosage. To overcome these limitations, several studies have aimed to develop a no-reference novel image quality metric that correlates well with radiologists’ opinion on image quality without any reference images (2, 4, 5).</p> <p>Nevertheless, due to the lack of open-source datasets specifically for CT IQA, experiments have been conducted with datasets that differ from each other, rendering their results incomparable and introducing difficulties in determining a standard image quality metric for CT imaging. Besides, unlike real low-dose CT images with quality degradation due to various combinations of artifacts, most studies are conducted with only one type of artifact (e.g., low-dose noise (6-11), view aliasing (12), metal artifacts (13), scattering (14-16), motion artifacts (17-22), etc.). Therefore, this challenge aims to 1) evaluate various NR-IQA models on CT images containing complex noise/artifacts, 2) to compare their correlations with scores produced by radiologists, and 3) to grant insights into the determination of the best-performing metric of CT imaging in terms of correlating with the perception of radiologists’.</p> <p>Furthermore, considering that low-dose CT images are achieved by reducing the number of projections per rotation and by reducing the X-ray current, the combination of two major artifacts, namely the sparse view streak and noise generated by these methods, is dealt with in this challenge so that the best-performing IQA model applicable in real clinical environments can be verified.</p> <p> </p> <p><strong>Funding Declaration:</strong></p> <p>This research was partly supported by Institute of Information & communications Technology Planning & Evaluation (IITP) grant funded by the Korea government(MSIT) (No.RS-2022-00155966, Artificial Intelligence Convergence Innovation Human Resources Development (Ewha Womans University)), and by the National Research Foundation of Korea (NRF-2022R1A2C1092072), and by the Korea Medical Device Development Fund grant funded by the Korea government (the Ministry of Science and ICT, the Ministry of Trade, Industry and Energy, the Ministry of Health & Welfare, the Ministry of Food and Drug Safety) (Project Number: 1711174276, RS-2020-KD000016).</p> <p> </p> <p><strong>References:</strong></p> <ol> <li>Lee W, Cho E, Kim W, Choi J-H.
