This paper presents a novel structure-preserving image decomposition operator called bilateral texture filter . As a simple modification of the original bilateral filter [Tomasi and Manduchi 1998], it performs local patch-based analysis of texture features and incorporates its results into the range filter kernel. The central idea to ensure proper texture/structure separation is based on patch shift that captures the texture information from the most representative texture patch clear of promine

This paper presents a novel scene text detection algorithm, Canny Text Detector, which takes advantage of the similarity between image edge and text for effective text localization with improved recall rate. As closely related edge pixels construct the structural information of an object, we observe that cohesive characters compose a meaningful word/sentence sharing similar properties such as spatial location, size, color, and stroke width regardless of language. However, prevalent scene text de

Background: Polypharmacy has become a global health problem and is associated with adverse health outcomes in the elderly. This study evaluated the prevalence of polypharmacy and hyper-polypharmacy in elderly patients in South Korea during 2010–2019. Methods: We analyzed the outpatient care of persons aged ≥65 years covered by National Health Insurance (NHI) using NHI claims data from 2010 to 2019. Polypharmacy was defined as the use of ≥5 medications, and hyper-polypharmacy was defined as the u

Abstract The neurobiological basis of social dysfunction and the high male prevalence in autism spectrum disorder (ASD) remain poorly understood. Although network alterations presumably underlie the development of autistic-like behaviors, a clear pattern of connectivity differences specific to ASD has not yet emerged. Because the heterogeneous nature of ASD hinders investigations in human subjects, we explored brain connectivity in an etiologically homogenous rat model of ASD induced by exposure

Purpose: The purpose of this study was to analyze the effects of empathy, resilience and self-care on compassion fatigue in oncology nurses. Methods: The study design was a descriptive survey and questionnaires were collected from December 1 to 15, 2013. Participants were 171 oncology nurses caring for cancer patients. Data was analyzed using independent t-test, Scheffetest, one-way ANOVA, Pearson correlation coefficient and hierarchical multiple regression with the SPSS/WIN 18.0 program. Result

Polypharmacy may cause adverse health outcomes in the elderly. This study examined the prevalence of continuous polypharmacy and hyper-polypharmacy, factors associated with polypharmacy, and the most frequently prescribed medications among older adults in South Korea. This was a retrospective observational study using National Health Insurance claims data. In total, 7,358,953 Korean elderly patients aged 65 years and older were included. Continuous polypharmacy and hyper-polypharmacy were define

Abstract Typical high dynamic range (HDR) imaging approaches based on multiple images have difficulties in handling moving objects and camera shakes, suffering from the ghosting effect and the loss of sharpness in the output HDR image. While there exist a variety of solutions for resolving such limitations, most of the existing algorithms are susceptible to complex motions, saturation, and occlusions. In this paper, we propose an HDR imaging approach using the coded electronic shutter which can

( Ba,Sr)TiO 3 (BST) thin films were prepared on Pt/SiO2/Si substrates by the pulse injection chemical vapor deposition (CVD) process, in which the vapor of precursors was allowed to flow periodically into the reaction chamber. The dielectric constants of BST thin films, which were deposited by pulse injection CVD, were slightly higher than those of continuous BST thin films. In addition, the leakage currents were lowered by an order of magnitude. 35 nm thick BST thin films, deposited by pulse in

Product line assets must be designed so that inclusion or exclusion of variable features causes little changes to components implementing other features. In order to achieve this goal, various relationships or dependencies that variable features have with other features must be analyzed thoroughly before designing product line assets. An object-oriented approach has been proposed to manage operational dependencies between features. However, it still suffers from code scattering and tangling prob

1910 Objectives The purpose of this study was to evaluate a newly developed integrin binding agent, 18F-RGD-K5 (alternative to 18F-Galacto-RGD) in breast cancer and compared with 18F-FDG PET scan. The uptake pattern of 18F-RGD-K5 was also compared with microvessel density in tumor specimen. Methods Twelve patients with primary or metastatic breast cancer were enrolled. 18F-FDG PET scan was performed within ±7 days of 18F-RGD-K5 PET scan. The maximum SUV within the lesions were measured in each s

Product line software engineering (PLSE) is a promising method for software reuse. For the key of success, a reusable and adaptable architecture design is necessary. In domain of mobile games product lines, architectures have some common structures because of circumstance properties of the domain and business constraints. In this paper, we classify them as architecture patterns. By doing this, we can expect increasing portability, reusability, adaptability, maintainability, and eventually produc
