Generalized nucleus segmentation techniques can contribute greatly to reducing the time develop and validate visual biomarkers for new digital pathology datasets. We summarize results of MoNuSeg 2018 Challenge whose objective was generalizable nuclei in pathology. The challenge an official satellite event MICCAI conference which 32 teams with more than 80 participants from geographically diverse institutes participated. Contestants were given a training set 30 images seven organs annotations...
Coherent imaging techniques provide an unparalleled multi-scale view of materials across scientific and technological fields, from structural to quantum devices, integrated circuits biological cells. Driven by the construction brighter sources high-rate detectors, coherent methods like ptychography are poised revolutionize nanoscale characterization. However, these advancements accompanied significant increase in data compute needs, which precludes real-time imaging, feedback decision-making...
The state-of-the art method of wound assessment is a manual, imprecise and time-consuming procedure. Per- formed by clinicians, it has limited reproducibility accuracy, large time consumption high costs. Novel technologies such as laser scanning microscopy, multi-photon optical coherence tomography hyper-spectral imaging, well devices relying on the structured light sensors, make accurate possible. However, methods have limitations due to costs may lack portability availability. In this...
To show feasibility of computerized techniques for ocular redness quantification in clinical studies, and to propose an automatic, objective method.Software the bulbar conjunctiva was developed. It provides interface manual automatic sclera segmentation along with automated alignment region interest enable estimation changes redness. The software also includes scoring methods: (1) contrast-limited adaptive histogram equalization (CLAHE) red-green-blue (RGB) color model, (2) product...
To compare the removal of simulated biofilm at two different implant-supported restoration designs with various interproximal oral hygiene aids.Mandibular models a missing first molar were fabricated and provided single implant analogues (centrally or distally placed) crown (conventional [CCD] alternative design [ACD]). Occlusion spray was applied to crowns simulate artificial biofilm. Thirty participants (dentists, dental hygienists, laypersons) equally divided asked clean areas five...
Blind and visually impaired persons face many challenges due to isolation, the most important is lacking education social immobility. Yet, since development of well-known white-red cane, only few advances have been made increase mobility blind people. GPS systems are often used for pedestrian navigation but lack precision, foremost in rural areas where needed. The aim IMAGO project therefore an inexpensive unobtrusive method persons. Navigation performed using structure from motion...
Abstract A system for fully automatic contact‐less image‐based measurement of volumetric flow rate in urban drainage structures is presented. The hardware includes two original equipment manufacturer cameras and a single‐board computer on which our custom image processing software running. value water discharge depends the surface velocity, level channel's geometry. estimated as difference between distances from camera to bottom. Camera‐to‐water distance recovered automatically using...
The state-of-the-art wound assessment is manually performed by clinicians. This ineffective and imprecise. Special devices have been developed for automation, but they are expensive often lack portability. We present a concept of low-cost system documentation analysis. Using computer vision techniques, 3D reconstructions wounds can be created from images taken with simple camera, such as those embedded in mobile phones.
Quantitative light-induced fluorescence (QLF) is widely used to assess the damage of a tooth due decalcification. In digital photographs, decalcification appears as white spot lesions, i.e. spots on surface. We propose novel multimodal registration approach for matching photographs and QLF images decalcified teeth. The based idea contour-to-pixel matching. Here, curve, which represents shape tooth, extracted from image using contour segmentation by binarization morphological processing. This...
When teaching robotics, instructors face the challenge of finding an effective approach to bridge theoretical concepts and practical applications. Both computer simulations hands-on laboratory experiments provide learners with opportunities for active, immersive, experiential learning. As students progress from introductory advanced topics theory practice, their performance is contingent upon earlier knowledge may increase, remain unchanged, or decrease. The question that arises whether...

Nowadays the measurements of chronic wounds are mostly performed manually by clinicians, despite on high limitations such method. Modern technologies make it possible to do accurate wound assessment. However, due costs and limited availability special equipment, methods not widely used. Here, we present a concept low-cost assessment system, which, with help computer vision techniques, will create dense 3D reconstructions from images taken hand-held camera. Our system also provide...
A novel approach for positioning using smartphones and image processing techniques is developed. Using structure from motion, 3D reconstructions of given tracks are created stored as sparse point clouds. Query images matched later to these models. High computational costs matching limited storage require compressing clouds without loss performance. In this work, localization improved memory requirements minimized. We assumed that the speed and, at same time, benefit reducing number points...
Digital cameras are often used in recent days for photographic documentation medical sciences. However, color reproducibility of same objects suffers from different illuminations and lighting conditions. This variation representation is problematic when the images segmentation measurements based on thresholds. In this paper, motivated by follow-up chronic wounds, we assess impact (i) gamma correction, (ii) white balancing, (iii) background unification, (iv) reference card-based correction....
Overflows in urban drainage structures, or sewers, must be prevented on time to avoid their undesirable consequences. An effective monitoring system able measure volumetric flow sewers is needed. Existing stateof-the-art technologies are not robust against harsh sewer conditions and, therefore, cause high maintenance expenses. Having the goal of fully automatic, and non-contact measurement we came up with an original innovative idea a vision-based for monitoring. On contrast existing...

The running average approach has long been perceived as the best choice for fusing depth measurements captured by a consumer-grade RGB-D camera into global 3D model. This strategy, however, assumes exact correspondences between points in model and images. Such assumption does not hold true many cases because of errors motion tracking, noise, occlusions, or inconsistent surface sampling during measurements. Accordingly, reconstructed models suffer unpleasant visual artifacts. In this paper,...
