Smart manufacturing enables an efficient manufacturing process by optimizing production and product transaction. The optimization is performed through data analytics that requires reliable and informative data as input. Therefore, in this paper, an accurate data capture approach based on a vision sensor is proposed. Three image recognition methods are studied to determine the best vision-based classification technique, namely Bag of Words (BOW), Spatial Pyramid Matching (SPM) and Convolutional Neural Network (CNN)...

Many plant diseases have distinct visual symptoms which can be used to identify and classify them correctly. This paper presents a potato disease classification algorithm which leverages these distinct appearances and the recent advances in computer vision made possible by deep learning. The algorithm uses a deep convolutional neural network training it to classify the tubers into five classes, namely, four disease classes and a healthy potato class. The database of images used in this study, containing potato tubers of different cultivars, sizes and diseases, was acquired, classified, and labeled manually by experts...

Accelerated ageing of the population results in an ever-increasing number of functionally dependent elderly persons. Even healthy older people experience self-care deficits due to decreased mobility, endurance and sensory loss. Residents in long-term care centres depend on caregivers for the majority of their activities of daily living.Dental services for functionally dependent seniors generally remain inadequate. Several factors may explain this situation, including the absence of government guidelines and the lack of initial and continuing training of both dental and non-dental personnel...

Deep convolutional networks (DCNNs) are achieving previously unseen performance in object classification, raising questions about whether DCNNs operate similarly to human vision. In biological vision, shape is arguably the most important cue for recognition. We tested the role of shape information in DCNNs trained to recognize objects. In Experiment 1, we presented a trained DCNN with object silhouettes that preserved overall shape but were filled with surface texture taken from other objects. Shape cues appeared to play some role in the classification of artifacts, but little or none for animals...

BACKGROUND: Deep learning has been recently applied to a multitude of computer vision and medical image analysis problems. Although recent research efforts have improved the state of the art, most of the methods cannot be easily accessed, compared or used by other researchers or clinicians. Even if developers publish their code and pre-trained models on the internet, integration in stand-alone applications and existing workflows is often not straightforward, especially for clinical research partners...

REVIEW
Sharmeela Saha, Jay B Wish
The responsibilities of a dialysis unit medical director are specified in the ESRD Conditions for Coverage and encompass multiple quality, safety, and educational domains. Many of these responsibilities require leadership skills that are neither intuitive nor acquired as part of the medical director's training. An effective medical director is able to shape the culture of the dialysis facility such that patients and staff feel free to communicate their concerns regarding suboptimal processes without fear of retribution, and there is a continuous iterative process of quality improvement and safety, which values input from all stakeholders...

Non-physical barriers, including the use of underwater strobe lights alone or paired with sound or bubbles, are being considered as a means to prevent the upstream migration of invasive silver carp Hypophthalmichthys molitrix and bighead carp H. nobilis. To optimize potential optical deterrents, it is necessary to understand the visual sensitivity of the fishes. Dark-adapted H. molitrix and H. nobilis were found to possess broad visual sensitivity between 470 nm to 620 nm with peak spectral sensitivity at 540 nm for H...

Cerebral microbleeds, which are small focal hemorrhages in the brain that are prevalent in many diseases, are gaining increasing attention due to their potential as surrogate markers of disease burden, clinical outcomes, and delayed effects of therapy. Manual detection is laborious and automatic detection and labeling of these lesions is challenging using traditional algorithms. Inspired by recent successes of deep convolutional neural networks in computer vision, we developed a 3D deep residual network that can distinguish true microbleeds from false positive mimics of a previously developed technique based on traditional algorithms...

We address the problem of prostate lesion detection, localization, and segmentation in T2W magnetic resonance (MR) images. We train a deep convolutional encoder-decoder architecture to simultaneously segment the prostate, its anatomical structure, and the malignant lesions. To incorporate the 3D contextual spatial information provided by the MRI series, we propose a novel 3D sliding window approach, which preserves the 2D domain complexity while exploiting 3D information. Experiments on data from 19 patients provided for the public by the Initiative for Collaborative Computer Vision Benchmarking (I2CVB) show that our approach outperforms traditional pattern recognition and machine learning approaches by a significant margin...

The priority of synaptic device researches has been given to prove the device potential for the emulation of synaptic dynamics and not to functionalize further synaptic devices for more complex learning. Here, we demonstrate an optic-neural synaptic device by implementing synaptic and optical-sensing functions together on h-BN/WSe2 heterostructure. This device mimics the colored and color-mixed pattern recognition capabilities of the human vision system when arranged in an optic-neural network. Our synaptic device demonstrates a close to linear weight update trajectory while providing a large number of stable conduction states with less than 1% variation per state...

Toxicity is an important factor in failed drug development, and its efficient identification and prediction is a major challenge in drug discovery. We have explored the potential of microscopy images of fluorescently labeled nuclei for the prediction of toxicity based on nucleus pattern recognition. Deep learning algorithms obtain abstract representations of images through an automated process, allowing them to efficiently classify complex patterns, and have become the state-of-the art in machine learning for computer vision...

To restore vision for the blind, several prosthetic approaches have been explored that convey raw images to the brain. So far, these schemes all suffer from a lack of bandwidth. An alternate approach would restore vision at the cognitive level, bypassing the need to convey sensory data. A wearable computer captures video and other data, extracts important scene knowledge, and conveys that to the user in compact form. Here, we implement an intuitive user interface for such a device using augmented reality: each object in the environment has a voice and communicates with the user on command...

BACKGROUND: Orthopedic operating room (OR) nurses entail specialized skills and training, which are not part of the regular curricula at most nursing college. Instead, many nursing students' exposure to orthopedic care in the orthopedic range is limited to occasional observational assignments. Additionally, teamwork is an important factor affecting the performance of the orthopedic OR nurses. This results in a knowledge gap in clinical nursing education. Problem and scripting based learning (PSBL) method is a crucial tool of pre-operative prepared improvement...

Visual dysfunctions and symptoms are commonly experienced after even mild traumatic brain injury (TBI) despite excellent visual acuity. All individuals who have experienced a TBI/concussion should be screened for vision symptoms and visual dysfunction. A TBI-specific eye examination is necessary to identify the visual sequelae of TBI and address any vision/ocular issues that may be contributing to other post-TBI complaints. A vision rehabilitation plan that includes vision therapy can improve visual dysfunction secondary to TBI...
