DeepPyramid+: Medical Image Segmentation using Pyramid View Fusion and Deformable Pyramid Reception [PDF]

open access: yesarXiv, 2023
Semantic Segmentation plays a pivotal role in many applications related to medical image and video analysis. However, designing a neural network architecture for medical image and surgical video segmentation is challenging due to the diverse features of relevant classes, including heterogeneity, deformability, transparency, blunt boundaries, and ...

Cataract influence on iris recognition performance [PDF]

open access: yesPhotonics Applications in Astronomy, Communications, Industry, and High-Energy Physics Experiments 2014, 929020 (2014), 2018
This paper presents the experimental study revealing weaker performance of the automatic iris recognition methods for cataract-affected eyes when compared to healthy eyes. There is little research on the topic, mostly incorporating scarce databases that are often deficient in images representing more than one illness.

Hierarchical method for cataract grading based on retinal images using improved Haar wavelet [PDF]

open access: yesarXiv, 2019
Cataracts, which are lenticular opacities that may occur at different lens locations, are the leading cause of visual impairment worldwide. Accurate and timely diagnosis can improve the quality of life of cataract patients. In this paper, a feature extraction-based method for grading cataract severity using retinal images is proposed.

Relevance-Based Compression of Cataract Surgery Videos [PDF]

open access: yesarXiv, 2023
In the last decade, the need for storing videos from cataract surgery has increased significantly. Hospitals continue to improve their imaging and recording devices (e.g., microscopes and cameras used in microscopic surgery, such as ophthalmology) to enhance their post-surgical processing efficiency.

2020 CATARACTS Semantic Segmentation Challenge [PDF]

open access: yesarXiv, 2021
Surgical scene segmentation is essential for anatomy and instrument localization which can be further used to assess tissue-instrument interactions during a surgical procedure. In 2017, the Challenge on Automatic Tool Annotation for cataRACT Surgery (CATARACTS) released 50 cataract surgery videos accompanied by instrument usage annotations.

Machine Learning for Cataract Classification and Grading on Ophthalmic Imaging Modalities: A Survey [PDF]

open access: yesMachine Intelligence Research,2022, 2020
Cataracts are the leading cause of visual impairment and blindness globally. Over the years, researchers have achieved significant progress in developing state-of-the-art machine learning techniques for automatic cataract classification and grading, aiming to prevent cataracts early and improve clinicians' diagnosis efficiency.

SegDenseNet: Iris Segmentation for Pre and Post Cataract Surgery [PDF]

open access: yesarXiv, 2018
Cataract is caused due to various factors such as age, trauma, genetics, smoking and substance consumption, and radiation. It is one of the major common ophthalmic diseases worldwide which can potentially affect iris-based biometric systems. India, which hosts the largest biometrics project in the world, has about 8 million people undergoing cataract ...
