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
Biometric recognition of infants using fingerprint, iris and ear biometrics

Author: Moolla, Yaseen ; De Kock, Antonie J ; Mabuza-Hocquet, Gugulethu P ; Ntshangase, Cynthia S ; Nelufule, Nthatheni ; Khanyile, Nontokozo P Date: Feb 2021 Biometric recognition is often used for adults for a variety of purposes where an individual’s identity must be ascertained. However, the biometric recognition of children is an unsolved challenge. Solving this challenge could protect children ... Read more
Circular interpolation techniques towards accurate segmentation of iris biometric images for infants

Author: Nelufule, Nthatheni ; Mabuza-Hocquet, Gugulethu P ; De Kock, Antonie J Date: Jan 2020 In most biometric modalities, recognition and authentication methods for adults have already been fully designed, developed and commercially available. However, for infants and children who are the most vulnerable population to abduction, ... Read more
Circular interpolation techniques towards accurate segmentation of iris biometric images for infants (conference paper)

Author: Nelufule, Nthatheni ; Mabuza-Hocquet, Gugulethu P ; De Kock, Antonie J Date: Jan 2020 In most biometric modalities, recognition and authentication methods for adults have already been fully designed, developed and commercially available. However, for infants and children who are the most vulnerable population to abduction, ... Read more
Ethnicity distinctiveness through iris texture features using Gabor filters

Author: Mabuza-Hocquet, Gugulethu P ; Nelwamondo, Fulufhelo V ; Marwala, T Date: Feb 2017 Research in iris biometrics has been focused on utilizing iris features as a means of identity verification and authentication. However, not enough research work has been done to explore iris textures to determine soft biometrics such as ... Read more
Ethnicity prediction and classification from iris texture patterns: A survey on recent advances

Author: Mabuza-Hocquet, Gugulethu P ; Nelwamondo, Fulufhelo V ; Marwala, T Date: Mar 2017 The prediction and classification of ethnicity based on iris texture patterns using image processing, artificial intelligence and computer vision techniques is still a recent topic in iris biometrics. While the large body of knowledge and ... Read more
Fusion of phase congruency and harris algorithm for extraction of iris corner points

Author: Mabuza-Hocquet, Gugulethu P ; Nelwamondo, Fulufhelo V Date: Dec 2015 Iris recognition uses automated techniques to extract iris features which are stored in a database as a feature template to be later used for individual identification and authentication. Strict image quality control is a basic requirement ... Read more
Iris image enhancement for feature recognition and extraction

Author: Mabuza-Hocquet, Gugulethu P ; Nelwamondo, Fulufhelo V Date: Oct 2012 Poor digital iris images prove to be a challenge when iris features have to be recognised and extracted for use in iris classification. To ensure the accuracy of a typical iris recognition system, acquired iris images have to undergo a ... Read more
Mitigating online sexual grooming cybercrime on social media using machine learning: A desktop survey

Author: Ngejane, Hombakazi C ; Eloff, J ; Mabuza-Hocquet, Gugulethu P ; Lefophane, Samuel Date: Aug 2018 Cyber threats such as identity deception, cyber bullying, identity theft and online sexual grooming have been witnessed on social media. These threats are disturbing to the society at large. Even more so to minors who are exposed to the ... Read more
Robust iris segmentation through parameterization of the Chan-Vese algorithm

Author: Mabuza-Hocquet, Gugulethu P ; Nelwamondo, Fulufhelo V ; Marwala, T Date: Jun 2015 The performance of an iris recognition system relies on automated processes from the segmentation stage to the matching stage. Each stage has traditional algorithms used successfully over the years. The drawback is that these algorithms assume ... 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
The use of U-Net lite and Extreme Gradient Boost (XGB) for glaucoma detection

Author: Afolabi, OJ ; Mabuza-Hocquet, Gugulethu P ; Nelwamondo, Fulufhelo V ; Paul, BS Date: Mar 2021 Glaucoma has been credited to be the foremost cause of preventable loss of sight in the world second only to cataract. Its effect on the eye is usually irreversible and can only be prevented by early detection. In this paper, we developed a ... Read more
