Scoliosis is a common spinal condition where the spine curves to side and thus deforms spine. Curvature estimation provides powerful index evaluate deformation severity of scoliosis. In current clinical diagnosis, standard curvature method for assessing quantitatively done by measuring Cobb angle, which angle between two lines, drawn perpendicular upper endplate uppermost vertebra involved lower lowest involved. However, manual measurement requires considerable time effort, along with...

The morphology and thermal stability of Pt particles deposited on Fe3O4 (111) films were studied by scanning tunneling microscopy (STM) temperature programmed desorption CO. Vacuum annealing at temperatures above 800 K led to significant sintering that reduced CO uptake a much higher extent than the surface area. A similar effect adsorption was observed after mild oxidation−reduction treatment 500 K. results are rationalized in terms strong metal−support interaction between Fe3O4, whereby...

The structural stability of an FeO(111) film supported on Pt(111) was studied by density functional theory (DFT) as a function oxygen pressure. results showed formation O-rich phases at elevated O2 pressures and revealed site specificity the oxidation process within coincidence (Moiré) structure between Pt(111), ultimately resulting in ordered pattern O−Fe−O trilayer islands, observed scanning tunneling microscopy (STM). In addition, high resolution STM images (√3 × √3)R30° superstructure...

Accurate automatic spike detection is highly beneficial to clinical assessment of epileptic electroencephalogram (EEG) data. In this paper, a new two-stage approach proposed for detection. First, the k-point nonlinear energy operator (k-NEO) adopted detect all possible candidates, then newly model with slow wave features applied these candidates classification. Experimental results show that system, using AdaBoost classifier, outperforms conventional method in both two- and three-class EEG...

Carpal tunnel syndrome commonly occurs in individuals working occupations that involve use of vibrating manual tools or tasks with highly repetitive and forceful exertion. In recent years, carpal has been evaluated by ultrasound imaging monitors median nerve movement. Conventional image analysis methods, such as the active contour model, are typically used to expedite automatic segmentation nerve, but these usually suffer from an arduous intervention. We propose a new convolutional neural...

Abstract With the continuous development of vehicle intelligence technology and active safety technology, autonomous emergency braking pedestrian (AEB-P) system has emerged as a crucial element contemporary automotive systems. However, there are still some deficiencies in control strategies utilized by current AEB-P system. It is imperative to design an that can adapt threshold strategy real-time based on driving conditions. The objective this paper propose with adaptive analyze its...

Dietary assessment is important in health maintenance and intervention many chronic conditions, such as obesity, diabetes cardiovascular disease. However, there currently a lack of convenient methods for measuring the volume food (portion size) real-life settings. We present computational method to estimate from single photographic image contained on typical dining plate. First, we calculate location with respect 3D camera coordinate system using plate scale reference. Then, segmented...

Scaphoid fractures frequently appear in injury radiograph, but approximately 20% are occult. While there few studies the fracture detection of X-ray scaphoid images, their effectiveness is insignificant detecting fractures. Traditional image processing technology had been applied to segment interesting areas it always suffered from requirements manual intervention and a large amount computational time. To date, models convolutional neural networks have widely medical recognition; thus, this...

Tuberculosis (TB) remains the leading cause of morbidity and mortality from infectious disease in developing countries. The sputum smear microscopy primary diagnostic laboratory test. However, microscopic examination is always time-consuming tedious. Therefore, an effective computer-aided image identification system needed to provide timely assistance diagnosis. current usually suffers complex color variations images, resulting plentiful false object detection. To overcome dilemma, we...

For better treatment outcomes, dentists usually use a set of parameters for orthodontic evaluation. In this study, new method is proposed to assist in obtaining reliable assessment these parameters. The based on dental panoramic radiographs and can be divided into four stages: image preprocessing, model training, tooth segmentation, first normalized enhanced. Then, the training stage consists shape energy function weight training. Next, we automatically segment contours an energy-minimized...

The authors propose a new ultrasonic image analysis system that can be utilized as an effective tool in classifying liver states normal, hepatitis, or cirrhosis. In this system, the first define suitable settings for device, then remove inhomogeneous structures from area of interest image, and then, by using forward sequential search method, look useful texture parameters co-occurrence matrix, statistical feature spectrum, fractal dimension descriptors. Finally, selected are fed into...

Image-based dietary assessment is important for health monitoring and management because it can provide quantitative objective information, such as food volume, nutrition type, calorie intake. In this paper, a new framework, 3D/2D model-to-image registration, presented estimating volume from single-view 2D image containing reference object (i.e., circular dining plate). First, the segmented background based on Otsu's thresholding morphological operations. Next, obtained user-selected, 3D...

ABSTRACT Liver fibrosis is currently described quite subjectively or, at best, semiquantitatively by scoring systems. In order to measure the severity of liver quantitatively and compare this with established methods, such as Knodell's system, colorimetric method conventional description reports, we undertook present study. A personal computer an image grabber card a microscope equipped computer‐controlled slide‐driver was used for morphometry. The principle behind morphometry based on...

Abstract The purpose of this study was to investigate the dynamic changes histopathology, biomechanical properties, echo intensity, and ultrasound features in a collagenase-induced tendinopathy model rat Achilles tendons, examine associations among features. Forty-two rats received an ultrasound-guided collagenase injection on their left needle puncture right ones as control. At four, eight, twelve weeks post-injury, tendons were examined via measurements histopathological ultrasonographic...
