Polyp Detection and Segmentation from Video Capsule Endoscopy: A Review [PDF]
Journal of Imaging, 3(1), 1, 2017, 2016 Video capsule endoscopy (VCE) is used widely nowadays for visualizing the gastrointestinal (GI) tract. Capsule endoscopy exams are prescribed usually as an additional monitoring mechanism and can help in identifying polyps, bleeding, etc. To analyze the large scale video data produced by VCE exams automatic image processing, computer vision, and ...

A deep learning framework for quality assessment and restoration in video endoscopy [PDF]
Medical Image Analysis, 101900(2020), 2019 Endoscopy is a routine imaging technique used for both diagnosis and minimally invasive surgical treatment. Artifacts such as motion blur, bubbles, specular reflections, floating objects and pixel saturation impede the visual interpretation and the automated analysis of endoscopy videos.

Twisted endoscopy from a sheaf-theoretic perspective [PDF]
arXiv, 2016 The standard theory of endoscopy for real groups has two parallel formulations. The original formulation of Langlands and Shelstad relies on methods in harmonic analysis. The subsequent formulation of Adams, Barbasch and Vogan relies on sheaf-theoretic methods. The original formulation was extended by Kottwitz and Shelstad to twisted endoscopy.

NanoNet: Real-Time Polyp Segmentation in Video Capsule Endoscopy and Colonoscopy [PDF]
arXiv, 2021 Deep learning in gastrointestinal endoscopy can assist to improve clinical performance and be helpful to assess lesions more accurately. To this extent, semantic segmentation methods that can perform automated real-time delineation of a region-of-interest, e.g., boundary identification of cancer or precancerous lesions, can benefit both diagnosis and ...

Galois characterization of Endoscopy for rational Siegel modular forms [PDF]
arXiv, 2003 We establish a relation between Galois reducibility and Endoscopy for genus 2 Siegel cusp forms which have rational eigenvalues and are unramified at ...

World Journal of Gastroenterology, 2009 Capsule endoscopy (CE) is a simple, safe, non-invasive, reliable technique, well accepted and tolerated by the patients, which allows complete exploration of the small intestine. The advent of CE in 2000 has dramatically changed the diagnosis and management of many diseases of the small intestine, such as obscure gastrointestinal bleeding, Crohn's ...

Poisson Summation and Endoscopy for $Sp(4,\mathbb R)$ [PDF]
Southeast Asian Bulletin of Mathematics, 40 (6) (2016), 837-856, 2014 In this paper we analyze the endoscopy for $\Sp(4,\mathbb R)$. The new results are a precise realization of the discrete series representations (in Section 2), a computation of their traces (Section 3) and an exact formula for the noncommutative Poisson summation and endoscopy of for this group (in Sections 4,5).

Poisson Summation and Endoscopy for SU(2,1) [PDF]
East-West J. of Mathematics: Vol. 17, No 2 (2015), 125-140, 2014 In this paper we analyze the endoscopy for $SU(2,1)$. The new results are a precise realization of the discrete series representations (in Section 2), a computation of their traces (Section 3) and an exact formula for the Poisson summation and endoscopy for this group (in Section 4).

South African medical journal = Suid-Afrikaanse tydskrif vir geneeskunde, 2006 In modern neurosurgery there has been a strong trend towards the use of minimally invasive techniques, one of which is intracranial endoscopy. Endoscopic third ventriculostomy (ETV) is the commonest procedure performed; it is used to treat hydrocephalus caused by an obstruction to the ventricular system anywhere distal to the mamillary bodies of the ...

Exposing Relative Endoscopy in Unitary Symmetric Spaces [PDF]
arXiv, 2014 We introduce a new class of symmetric space orbital integrals important for applications in certain relative trace formulas appearing in the theory of automorphic representations. We verify a fundamental lemma for $U_2\times U_2\hookrightarrow U_4$ via an explicit calculation, showing strong evidence that there is a general theory of endoscopy lurking ...
