Optic cup localization/segmentation has attracted much attention from medical imaging researchers, since it is the primary image component clinically used for identifying glaucoma, which is a leading cause of blindness. In this work, we present an optic cup localization framework based on local patch reconstruction, motivated by the great success achieved(More)
Optical coherence tomography (OCT) is a micrometer-scale, cross-sectional imaging modality for biological tissue. It has been widely used for retinal imaging in ophthalmology. Speckle noise is problematic in OCT. A raw OCT image/volume usually has very poor image quality due to speckle noise, which often obscures the retinal structures. Overlapping scan is(More)
In recent years, there has been increasing interest in the use of automatic computer-based systems for the detection of eye diseases including glaucoma. However, these systems are usually standalone software with basic functions only, limiting their usage in a large scale. In this paper, we introduce an online cloud-based system for automatic glaucoma(More)
The maturity of healthcare IoT technology which connects medical devices and applications to healthcare IT systems through internet has driven the rapid growth of healthcare. In recent years, great effort has been spent to improve ocular disease screening and diagnosis using advanced image and data analysis techniques. However, the developed systems are not(More)
In recent years, there has been increasing interest in the use of automatic computer-based systems for the detection of eye diseases such as glaucoma, age-related macular degeneration and diabetic retinopathy. However, in practice, retinal image quality is a big concern as automatic systems without consideration of degraded image quality will likely(More)
The software correlator system (SCS) is a key module of Chinese VLBI (Very Long Baseline Interferometry) Network (CVN). The main tasks of SCS include data pre-processing, fringe-searching, correlation, and phase correction signal extraction. In this paper, we propose four approaches for high-speed VLBI data preprocessing on the universal PC-server platform,(More)
