Occlusion and lack of visibility in crowded cluttered scenes make it difficult to track individual people correctly consistently, particularly a single view. We present multi-view approach solving this problem. In our we neither detect nor objects from any camera or pair; rather evidence is gathered all the cameras into synergistic framework detection tracking results are propagated back each Unlike other approaches that require fully calibrated views purely image-based uses only 2D...
Abstract The intestinal immune system is emerging as an important contributor to obesity-related insulin resistance, but the role of B cells in this context unclear. Here, we show that high fat diet (HFD) feeding alters IgA + and a critical regulator glucose homeostasis. Obese mice have fewer less secretory IgA-promoting mediators. HFD-fed IgA-deficient dysfunctional metabolism, phenotype can be recapitulated by adoptive transfer intestinal-associated pan-B cells. Mechanistically, crucial...
Stiffness in the tissue microenvironment changes most diseases and immunological conditions, but its direct influence on immune system is poorly understood. Here, we show that static tension impacts cell function, maturation, metabolism. Bone-marrow-derived and/or splenic dendritic cells (DCs) grown vitro at physiological resting stiffness have reduced proliferation, activation, cytokine production compared with under higher stiffness, mimicking fibro-inflammatory disease. Consistently, DCs...
Background and Aims Nonalcoholic steatohepatitis is rapidly becoming the leading cause of liver failure indication for transplantation. Hepatic inflammation a key feature NASH but immune pathways involved in this process are poorly understood. B lymphocytes cells adaptive system that critical regulators responses. However, role pathogenesis potential mechanisms to their activation unclear. Approach Results In study, we report livers accumulate with elevated pro‐inflammatory cytokine...
We address the issue of tracking moving objects in an environment covered by multiple uncalibrated cameras with overlapping fields view, typical most surveillance setups. In such a scenario, it is essential to establish correspondence between tracks same object, seen different cameras, recover complete information about object. call this problem consistent labeling when cameras. employ novel approach finding limits field view (FOV) each camera as visible other show that, if FOV lines are...
In this paper we present a novel approach using 4D (x,y,z,t) action feature model (4D-AFM) for recognizing actions from arbitrary views. The 4D-AFM elegantly encodes shape and motion of actors observed multiple modeling process starts with reconstructing 3D visual hulls at each time instant. Spatiotemporal features are then computed in view by analyzing the differential geometric properties spatio-temporal volumes (3D STVs) generated concatenating actor's silhouette over course (x, y, t)....
Non-alcoholic fatty liver disease (NAFLD) covers a wide spectrum of pathology ranging from simple to non-alcoholic steatohepatitis (NASH). Notably, immune cell-driven inflammation is key mechanism in the transition more serious NASH. Although exercise training effective ameliorating obesity-related diseases, underlying mechanisms beneficial effects remain unclear. It unknown whether there an optimal modality and intensity treat NAFLD. The objective this study was determine high-intensity...
Video segmentation is different from of a single image. While several correct solutions may exist for segmenting image, there needs to be consistency among segmentations each frame video segmentation. Previous approaches concentrate on motion, or combine motion and color information in batch fashion. We propose maximum posteriori probability (MAP) framework that uses multiple cues, like spatial location, assign weights terms, which are adjusted at every pixel, based confidence measure...
Generative Adversarial Networks (GANs) have been shown to produce synthetic face images of compelling realism. In this work, we present a conditional GAN approach generate contextually valid facial expressions in dyadic human interactions. contrast previous work employing conditions related attributes generated identities, focused on dyads an attempt model the relationship and influence one person's reaction other. To end, introduced two level optimization GANs interviewer-interviewee first...
Abstract Background/objectives Low-grade chronic inflammation in visceral adipose tissue and the intestines are important drivers of obesity associated insulin resistance. Bioactive compounds derived from plants an source potential novel therapies for treatment diseases. In search new immune based treatments resistance, we screened relevant anti-inflammatory properties 20 plant-based extracts. Methods We extracts to assess preferential production IL-10 compared TNFα, specifically targetting...
Multiple cameras are needed to cover large environments for monitoring activity. To track people successfully in multiple perspective imagery, one needs establish correspondence between objects captured cameras. We present a system tracking uncalibrated The is able discover spatial relationships the camera fields of view and use this information correspond different views same person. employ novel approach finding limits field (FOV) as visible other Using information, when person seen...
In this paper, a novel object class detection method based on 3D modeling is presented. Instead of using complicated mechanism for relating multiple 2D training views, the proposed establishes spatial connections between these views by mapping them directly to surface model. The shape an reconstructed homographic framework from set model around and represented volume consisting binary slices. Features are computed in each view mapped same framework. To generalize detection, features...
In this paper we present an algorithm for the autonomous navigation of unmanned aerial vehicle (UAV) following a moving target. The UAV in consideration is fixed wing aircraft that has physical constraints on airspeed and maneuverability. target however not considered to be constrained can move any general pattern. We show single circular pattern works targets at speed with where other methods switch between different strategies scenarios. Simulation performed takes into also needs visually...
Adrenaline and noradrenaline are produced within the heart from neuronal non-neuronal sources. These adrenergic hormones have profound effects on cardiovascular development function, yet relatively little information is available about specific tissue distribution of cells adult heart. The purpose present study was to define anatomical localization derived an lineage To accomplish this, we performed genetic fate-mapping experiments where mice with cre-recombinase (Cre) gene inserted into...
Background: Diabetes mellitus (DM) is a syndrome of chronically elevated glucose level in the blood either due to insulin resistance, deficiency or both. In addition, it may occur defective metabolism carbohydrates, fats and proteins. There are 3 main types DM: Type 2 DM more prevalent adults typically relative deficiency, children leads type 1; lastly, gestational diabetes occurs during pregnancy resulting from an imbalance placental hormones. Introduction: Insulin, Biguanides Sulfonylureas...
