Leveraging Surgical Activity Grammar for Primary Intention Prediction in Laparoscopy Procedures

ICRA 2025

Surgical procedures are inherently complex and dynamic, with intricate dependencies and various execution paths. Accurate identification of the intentions behind critical actions, referred to as Primary Intentions (PIs), is crucial to understanding and planning the procedure. This paper presents a n

Graph-Based Spatial Reasoning for Tracking Landmarks in Dynamic Laparoscopic Environments

RA-L 2024

Accurate anatomical landmark tracking is crucial yet challenging in laparoscopic surgery due to the changing appearance of landmarks during dynamic tool-anatomy interactions and visual domain shifts between cases. Unlike appearance-based detection methods, this work proposes a novel graph-based appr

Emotion Controllable Speech Synthesis Using Emotion-Unlabeled Dataset with the Assistance of Cross-Domain Speech Emotion Recognition

ICASSP 2021accepted

Neural text-to-speech (TTS) approaches generally require a huge number of high quality speech data, which makes it difficult to obtain such a dataset with extra emotion labels. In this paper, we propose a novel approach for emotional TTS synthesis on a TTS dataset without emotion labels. Specificall…
