An Elastic Image Registration Approach for Wireless Capsule Endoscope Localization

no code implementations23 Apr 2015 Isabel N. Figueiredo, Carlos Leal, Luís Pinto, Pedro N. Figueiredo, Richard Tsai

The results of the experimental tests with real WCE video frames show the good performance of the proposed approach, when elastic deformations of the small intestine are involved in successive frames, and its superiority with respect to a multiscale affine image registration, which accounts for rigid-like deformations only and discards elastic deformations.

Automated polyp detection in colon capsule endoscopy

no code implementations8 May 2013 Alexander V. Mamonov, Isabel N. Figueiredo, Pedro N. Figueiredo, Yen-Hsi Richard Tsai

The algorithm acts as a binary classifier, which labels the frame as either containing polyps or not, based on the geometrical analysis and the texture content of the frame.
