Constrained Visual-Inertial Localization With Application And Benchmark in Laparoscopic Surgery
Regine Hartwig, Daniel Ostler, Jean-Claude Rosenthal +3
We propose a novel method to tackle the visual-inertial localization problem for constrained camera movements. We use residuals from the different modalities to jointly optimize a…
OperA: Attention-Regularized Transformers for Surgical Phase Recognition
Tobias Czempiel, Magdalini Paschali, Daniel Ostler +3
In this paper we introduce OperA, a transformer-based model that accurately predicts surgical phases from long video sequences. A novel attention regularization loss encourages the…
The TUM LapChole dataset for the M2CAI 2016 workflow challenge
Ralf Stauder, Daniel Ostler, Michael Kranzfelder +3
In this technical report we present our collected dataset of laparoscopic cholecystectomies (LapChole). Laparoscopic videos of a total of 20 surgeries were recorded and annotated w…
