    • Advancing Hyperacuity for Vision Screening 

      Mohammed, Abdul Rasheed (University of Waterloo, 2023-09-22)
      Introduction: The human visual system is extremely sensitive to certain spatial visual tasks. It can detect the subtle misalignment of closer objects to a degree of 2-5 arcseconds, which is smaller than the foveal cone ...
    • Assessment of ocular aberrations at scaled pupil size and reduced Shack-Hartmann spot number 

      Ommani, Abbas (University of Waterloo, 2019-05-07)
      Wavefront aberrations describe the optical imperfections of the eye by measuring the complete refractive elements of the eye. However, the reliability of ocular aberration is uncertain under some challenges and issues. ...
    • Automated Cataract Grading using Smartphone Images 

      Nasir zonouzi, Mona (University of Waterloo, 2021-02-02)
      A cataract is an age-related eye disease and is one of the leading ophthalmological public health problems in developed and developing countries. Early detection of cataracts is necessary to preserve sight and prevent the ...
    • Automated Segmentation of Retinal Optical Coherence Tomography Images 

      Roy, Priyanka (University of Waterloo, 2018-08-21)
      Aim. Optical Coherence Tomography (OCT) is a fast and non-invasive medical imaging technique which helps in the investigation of each individual retinal layer structure. For early detection of retinal diseases and the study ...
    • Deep Generative Modeling Based Retinal Image Analysis 

      Sengupta, Sourya (University of Waterloo, 2020-06-16)
      In the recent past, deep learning algorithms have been widely used in retinal image analysis (fundus and OCT) to perform tasks like segmentation and classification. But to build robust and highly efficient deep learning ...
    • Developing algorithms for the analysis of retinal Optical Coherence Tomography images 

      Gholami, Peyman (University of Waterloo, 2018-09-04)
      Vision loss, with a prevalence loss greater than 42 million in the United States is one of the major challenges of today's health-care industry and medical science. Early detection of different retinal-related diseases ...
    • Diabetic retinopathy grading with respect to the segmented lesions 

      Kheradfallah, Hoda (University of Waterloo, 2022-05-19)
      One of the leading causes of irreversible vision loss is Diabetic Retinopathy (DR). The International Clinical Diabetic Retinopathy scale (ICDRS) provides grading criteria for DR. Deep Convolutional Neural Networks (DCNNs) ...
    • Estimation of Heading direction Using Optic Flow 

      Eshnina, Najwa (University of Waterloo, 2019-08-26)
      Background The purpose of this study was to investigate the effect of the reduction of the uniocular light luminance as well as the effect of unequal retinal image sizes by using uniocular size lenses, on the heading ...
    • Explainable AI for retinal OCT diagnosis 

      Brar, Amitojdeep Singh (University of Waterloo, 2021-01-20)
      Artificial intelligence methods such as deep learning are leading to great progress in complex tasks that are usually associated with human intelligence and experience. Deep learning models have matched if not bettered ...
    • Motion Processing of Reverse Phi 

      Kuppuswamy Parthasarathy, Mohana (University of Waterloo, 2019-11-18)
      Introduction: When the contrast of the successive images is reversed for a target in an apparent motion stimulus, the perceived direction is reversed, i.e., opposite of phi motion, which is an integration of the sequential ...
    • A novel Automatic Optic Disc and Cup Image Segmentation System for Diagnosing Glaucoma using RIGA dataset 

      Almazroa, Ahmed (University of Waterloo, 2016-04-07)
      The optic nerve head (ONH) of the retina is a very important landmark of the fundus and is altered in optic nerve pathology especially glaucoma. Numerous imaging systems are available to capture the retinal fundus and from ...
    • Psychophysical Studies Of Motion Perception In Autism Spectrum Disorders 

      Bakroon, Asmaa (University of Waterloo, 2019-05-23)
      Introduction Studies have shown considerable evidence of visual dysfunction in Autism Spectrum Disorders (ASD). Motion perception research in ASD reports a superior performance in processing motion information of fine ...
