Comparative validation of surgical phase recognition, instrument keypoint estimation, and instrument instance segmentation in endoscopy: Results of the PhaKIR 2024 challenge
Tobias Rueckert, David Rauber, Raphaela Maerkl +58
Reliable recognition and localization of surgical instruments in endoscopic video recordings are foundational for a wide range of applications in computer- and robot-assisted minim…
MuST: Multi-Scale Transformers for Surgical Phase Recognition
Alejandra Pérez, Santiago Rodríguez, Nicolás Ayobi +3
Phase recognition in surgical videos is crucial for enhancing computer-aided surgical systems as it enables automated understanding of sequential procedural stages. Existing method…
SAR-RARP50: Segmentation of surgical instrumentation and Action Recognition on Robot-Assisted Radical Prostatectomy Challenge
Dimitrios Psychogyios, Emanuele Colleoni, Beatrice Van Amsterdam +47
Surgical tool segmentation and action recognition are fundamental building blocks in many computer-assisted intervention applications, ranging from surgical skills assessment to de…
Pixel-Wise Recognition for Holistic Surgical Scene Understanding
Nicolás Ayobi, Santiago Rodríguez, Alejandra Pérez +8
This paper presents the Holistic and Multi-Granular Surgical Scene Understanding of Prostatectomies (GraSP) dataset, a curated benchmark that models surgical scene understanding as…
STRIDE: Street View-based Environmental Feature Detection and Pedestrian Collision Prediction
Cristina González, Nicolás Ayobi, Felipe Escallón +8
This paper introduces a novel benchmark to study the impact and relationship of built environment elements on pedestrian collision prediction, intending to enhance environmental aw…
MATIS: Masked-Attention Transformers for Surgical Instrument Segmentation
Nicolás Ayobi, Alejandra Pérez-Rondón, Santiago Rodríguez +1
We propose Masked-Attention Transformers for Surgical Instrument Segmentation (MATIS), a two-stage, fully transformer-based method that leverages modern pixel-wise attention mechan…
Towards Holistic Surgical Scene Understanding
Natalia Valderrama, Paola Ruiz Puentes, Isabela Hernández +6
Most benchmarks for studying surgical interventions focus on a specific challenge instead of leveraging the intrinsic complementarity among different tasks. In this work, we presen…
Panoptic Narrative Grounding
C. González, N. Ayobi, I. Hernández +3
This paper proposes Panoptic Narrative Grounding, a spatially fine and general formulation of the natural language visual grounding problem. We establish an experimental framework…
