Long-Term Temporally Consistent Unpaired Video Translation from Simulated Surgical 3D Data
Dominik Rivoir, Micha Pfeiffer, Reuben Docea +4
Research in unpaired video translation has mainly focused on short-term temporal consistency by conditioning on neighboring frames. However for transfer from simulated to photoreal…
Non-Rigid Volume to Surface Registration using a Data-Driven Biomechanical Model
Micha Pfeiffer, Carina Riediger, Stefan Leger +5
Non-rigid registration is a key component in soft-tissue navigation. We focus on laparoscopic liver surgery, where we register the organ model obtained from a preoperative CT scan…
Generating large labeled data sets for laparoscopic image processing tasks using unpaired image-to-image translation
Micha Pfeiffer, Isabel Funke, Maria R. Robu +12
In the medical domain, the lack of large training data sets and benchmarks is often a limiting factor for training deep neural networks. In contrast to expensive manual labeling, c…
Learning Soft Tissue Behavior of Organs for Surgical Navigation with Convolutional Neural Networks
Micha Pfeiffer, Carina Riediger, Jürgen Weitz +1
Purpose: In surgical navigation, pre-operative organ models are presented to surgeons during the intervention to help them in efficiently finding their target. In the case of soft…
