A New Shearlet Framework for Image Denoising
Traditional noise removal methods like Non-Local Means create spurious boundaries inside regular zones. Visushrink removes too many coefficients and yields recovered images that are overly smoothed. In Bayesshrink method, sharp features are preserved. However, PSNR (Peak Signal-to-Noise Ratio) is considerably low. BLS-GSM generates some discontinuous information during the course of denoising a...
متن کاملComparison among nasopharyngeal swab, nasal wash, and oropharyngeal swab for respiratory virus detection in adults with acute pharyngitis
BACKGROUND Acute pharyngitis is frequently seen in primary care. Acute viral pharyngitis may be easily misdiagnosed as acute bacterial pharyngitis. Laboratory-confirmed diagnosis of respiratory viruses is recommended. The purpose of this study was to compare the sensitivities among oropharyngeal swab (OPS), nasopharyngeal swab (NPS), and nasal wash (NW) in adults with acute pharyngitis. METHO...
متن کاملComparison among Nasopharyngeal Swab, Nasal Wash and Oropharyngeal Swab for Respiratory Viruses Detection in Adults with Acute Pharyngitis
Background: Acute pharyngitis is one of the most common illnesses for which patients visit primary care physicians. Its etiology is primarily viral in adults. Only about 10% of cases have a bacterial cause. Nonetheless, a total of 78-98% of adults with acute pharyngitis was treated with antibiotics. Thus, virological investigation prior to treating would support the appropriate use of antiviral...
متن کاملNew benchmark for image segmentation evaluation
bstract. Image segmentation and its performance evaluation are ery difficult but important problems in computer vision. A major hallenge in segmentation evaluation comes from the fundamental onflict between generality and objectivity: For general-purpose egmentation, the ground truth and segmentation accuracy may not e well defined, while embedding the evaluation in a specific appliation, the e...
متن کاملComparison of throat and nasopharyngeal swab specimens for culture diagnosis of Bordetella pertussis infection.
During a 9-month period, we evaluated the relative sensitivity of throat and nasopharyngeal swab cultures for isolation of Bordetella pertussis. Of 38 pertussis cases, 36 (95%) had positive nasopharyngeal cultures, while only 16 of 36 (44%) had positive throat cultures. There were no cases of nasopharyngeal-negative, throat-positive cultures. The sensitivity of the direct fluorescent-antibody t...
