This paper presents a novel learning-based method for single image super-resolution (SR). Given an input low-resolution image and its image pyramid, we propose to perform context-constrained image segmentation and construct an image segment dataset with different context categories. By learning context-specific image sparse representation, our method aims(More)
Learning-based approaches for super-resolution (SR) have been studied in the past few years. In this paper, a novel single-image SR framework based on the learning of sparse image representation with support vector regression (SVR) is presented. SVR is known to offer excellent generalization ability in predicting output class labels for input data. Given a(More)
Surgical repair of tetralogy of Fallot (TOF) in countries with sound medical care systems is seldom delayed until adolescence. This study investigated the clinical profile and the surgical outcomes in such a population from Taiwan. Between 1970 and 2009, 179 TOF patients (56% male) received total repair at 19.2 ± 8.3 (10–49) years of age. We reviewed the(More)
Parameters from cardiopulmonary exercise test (CPET) are useful prognostic factors for patients with repaired tetralogy of fallot (TOF). Its application in exercise prescription remains unclear. This study sought to define its role. We made current exercise recommendations in repaired TOF patients according to European Society of Cardiology (ESC) guideline,(More)
BACKGROUND The aim of the present study was to determine the rate of early-onset biliary atresia (BA) and its implications, for embryonic-type BA in Taiwan, a high-prevalence area for BA. The relationship between the timing of disease onset and congenital extrahepatic anomalies was also identified. METHODS Medical records of 130 infants born in Taiwan(More)
BACKGROUND Anterior mediastinal tumors in pediatric patients may cause severe cardiorespiratory compromise and sudden collapse, especially when anesthesia or analgesic is required. METHOD We report a 15-year-old boy with a huge anterior mediastinal tumor that caused complete obliteration of right pulmonary artery and left bronchus, that is, complete(More)
BACKGROUND Right ventricular (RV) outflow tract obstruction (RVOTO) might protect the RV from adverse remodeling caused by significant pulmonary regurgitation (PR) in patients with repaired tetralogy of Fallot (rTOF), but the underlying mechanisms and influences on exercise tolerance remain unclear. This study sought to investigate the impacts from mild(More)
We propose a novel learning-based method for single image super-resolution (SR). Given a low-resolution input image and its image pyramid, we advance a context-constrained image segmentation to construct a super-pixel database with different context categories for learning purposes. By utilizing context-specific image sparse representation, our method aims(More)
