Robustly computing the skeletons of objects in natural images is difficult due to the large variations in shape boundaries and the large amount of noise in the images. Inspired by recent findings in neuroscience, we propose the Skeleton Filter, which is a novel model for skeleton extraction from natural images. The Skeleton Filter consists of a pair of oppositely oriented Gabor-like filters; by applying the Skeleton Filter in various orientations to an image at multiple resolutions and fusing the results, our system can robustly extract the skeleton even under highly noisy conditions. We evaluate the performance of our approach using challenging noisy text datasets and demonstrate that our pipeline realizes state-of-the-art performance for extracting the text skeleton. Moreover, the presence of Gabor filters in the human visual system and the simple architecture of the Skeleton Filter can help explain the strong capabilities of humans in perceiving skeletons of objects, even under dramatically noisy conditions.

Inferior vena cava (IVC) filters are commonly used in patients at risk for life-threatening pulmonary embolism. Since the Mobin-Uddin filter was introduced in 1967, numerous other IVC filters have bee...
Herein we report that the Thomson Standard and eXtreme/FV® filter vials (0.2 μm polyvinylidene difluoride filter membrane) are as effective as gold standard microporous membrane-based syringe filt...
Complex inferior vena cava (IVC) filter retrieval was usually in need of advanced techniques. Filter strut endothelialization without tilt of the filter was still one of the challenges. Therefore, we ...
Filters are commonly used to reduce noise and improve data quality. Filter theory is part of a scientist's training, yet the impact of filters on interpreting data is not always fully appreciated. Thi...
Syringe filters are used to separate solids from liquids prior to analysis of poly- and perfluoroalkyl substances (PFASs). This is a critical step in sample preparation, as losses of PFASs to the filt...
This study was designed to assess the safety of retrieval of the Bard Recovery® G2® Filter System. The G2 filter is an FDA-cleared device for inferior vena caval interruption in patients...
The investigation is designed to verify that clinical use of the vena cava filter does not raise new questions of safety or effectiveness compared to currently-marketed permanent filters.
The goal of this study is to determine the biomarkers of exposure and harm as well as the pattern of product purchase when ventilated vs. unventilated cigarettes are available in the marke...
Since 2003, that the first retrievable IVC filter was introduced in the U.S,improvements have been made in the filter design to resolve problems of structural integrity and increase the...
Main objective: to demonstrate that the diagnostic quality associated with the acquisition mode with tin filter, evaluated in a subjective way, is not inferior to that associated with the ...
A plant genus of the family PONTEDERIACEAE that is used as a biological filter for treating wastewater.
Techniques for using whole blood samples collected on filter paper for a variety of clinical laboratory tests.
Improvement in the quality of an x-ray image by use of an intensifying screen, tube, or filter and by optimum exposure techniques. Digital processing methods are often employed.
A suborder of CRUSTACEA, order Diplostraca, comprising the water fleas. They are benthic filter feeders that consume PHYTOPLANKTON. The body is laterally compressed and enclosed in a bivalved carapace, from which the head extends.
The layer of EXTRACELLULAR MATRIX that lies between the ENDOTHELIUM of the glomerular capillaries and the PODOCYTES of the inner or visceral layer of the BOWMAN CAPSULE. It is the product of these two cell types. It acts as a physical barrier and an ion-selective filter.
Standard antiretroviral therapy (ART) consists of the combination of at least three antiretroviral (ARV) drugs to maximally suppress the HIV virus and stop the progression of HIV disease. Huge reductions have been seen in rates of death and suffering whe...
