In this paper, we investigate a novel content-based approach of linking medical images with relevant video segments arising from endoscopic procedures. We propose to approximate the video segments' content-based features by gradient-based signatures and to index these signatures with the Minkowski distance in order to determine the most query-like video segments efficiently. We benchmark our approach on a large endoscopic image and video archive and show that our approach achieves a significant improvement in efficiency in comparison to the state-of-the-art while maintaining high accuracy.}, doi = {10.1109/BigMM.2017.44}, keywords = {feature signatures, laparoscopic video, medical endoscopy, motion analysis, similarity search, video retrieval}, language = {EN}, location = {Laguna Hills, California, USA}, talkdate = {2017.04.19}, talktype = {registered}, url = {http://ieeexplore.ieee.org/document/7966709/} }
