Motion-Based Weak Supervision for Video Parsing with Application to Colonoscopy [PDF]
arXiv, 2022 We propose a two-stage unsupervised approach for parsing videos into phases. We use motion cues to divide the video into coarse segments. Noisy segment labels are then used to weakly supervise an appearance-based classifier. We show the effectiveness of the method for phase detection in colonoscopy videos.

Computer-assisted polyp matching between optical colonoscopy and CT colonography: a phantom study
, 2015 Potentially precancerous polyps detected with CT colonography (CTC) need to be removed subsequently, using an optical colonoscope (OC). Due to large colonic deformations induced by the colonoscope, even very experienced colonoscopists find it difficult ...

Containerless emulsification of acoustically levitated composite drop
Droplet, EarlyView.Emulsions are inherently thermodynamically unstable dispersions that are widely involved in food processing, cosmetic preparation, and drug delivery. The existing ultrasonic emulsification techniques mainly rely on the direct contact between the sonicator probe and liquids, which caused localized high temperature and pressure within the liquid and ...
