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

2020 CATARACTS Semantic Segmentation Challenge [PDF]
arXiv, 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.
