Assessment of the ISNT rule on publicly available datasets

Author: Oluwatobi, JA ; Mabuza-Hocquet, Gugulethu P ; Nelwamondo, Fulufhelo V Date: Dec 2019 The ISNT rule is a technique that has been used to detect glaucoma from fundus im-ages. The rule states that for a healthy fundus image, the segmented optic disc can be divided into four neuro-retina rim quadrants namely; the Inferior, Superior, ... Read more
The effects of segmentation-based shadow removal on across-date settlement type classification of panchromatic QuickBird images

Author: Luus, FPS ; Van den Bergh, F ; Maharaj, BTJ Date: Jun 2013 Settlement classifiers for multitemporal satellite image analysis have to overcome numerous difficulties related to across-date variances in viewing- and illumination geometry. Shadow anisotropy is a prominent contributing factor in classifier ... Read more
Feature selection and classification of oil spill from vessels using Sentinel-1 wide–swath synthetic aperture radar data

Author: Mdakane, Lizwe W ; Kleynhans, W Date: Oct 2020 Oil spills are often caused by vessels when dumping oily bilge wastewater at sea (also referred to as bilge dumping). In an synthetic aperture radar (SAR) image, oil spills dampen the radar energy return and appear as linearly shaped dark ... Read more
Figure detection and part label extraction from patent drawing images

Author: Cronje, J Date: Nov 2012 The US Patent and Trademark Office, together with the NASA Tournament Lab, launched a contest to develop specialized algorithms to help bring the seven million patents presently in the patent archive into the digital age. The contest was ... Read more
Multi-resolution segmentation of solar photovoltaic systems using deep learning

Author: Kleebauer, M ; Marz, Christopher A ; Reudenbach, C ; Braun, M Date: Dec 2023 In the realm of solar photovoltaic system image segmentation, existing deep learning networks focus almost exclusively on single image sources both in terms of sensors used and image resolution. This often prevents the wide deployment of such ... Read more
Performance analysis of machine learning classifiers for pothole road anomaly segmentation

Author: Bello-Salau, H ; Onumanyi, Adeiza J ; Adebiyi, RF ; Adedokun, EA ; Hancke, Gp Date: Jun 2021 Recently, machine learning (ML) classifiers are being widely deployed in many intelligent transportation systems towards improving the safety and comfort of passengers as well as to ease and enhance road navigation. However, the comparative ... Read more
Segmentation of optic cup and disc for diagnosis of glaucoma on retinal fundus images

Author: Joshua, AO ; Nelwamondo, Fulufhelo V ; Mabuza-Hocquet, Gugulethu P Date: Jan 2019 Glaucoma has been attributed to be the leading cause of blindness in the world second only to diabetic retinopathy. About 66.8 million people in the world have glaucoma and about 6.7 million are suffering from blindness as a result of glaucoma. ... Read more
The use of area covered by blood vessels in fundus images to detect glaucoma

Author: Oluwatobi, JA ; Nelwamondo, Fulufhelo V ; Mabuza-Hocquet, Gugulethu P Date: Dec 2019 Several techniques have been employed to detect glaucoma from optic discs. Some techniques involve the use of the optic cup-to-disc ratio (CDR) while others use the neuro-retinal rim width of the optic disc. In this work, we use the area ... Read more
