To this end, we propose a very flexible distributed video search system that combines many ideas of related work in a novel and collaborative way, such that several users can work together and explore the video archive in a complementary manner. The main interface is a perspective Feature Map, which shows keyframes of shots arranged according to a selected content similarity feature (e.g., color, motion, semantic concepts, etc.). This Feature Map is accompanied by additional views, which allow users to search and filter according to a particular content feature. For collaboration of several users we provide a cooperative heatmap that shows a synchronized view of inspection actions of all users. Moreover, we use collaborative re-ranking of shots (in specific views) based on retrieved results of other users.}, doi = {10.1007/978-3-319-51814-5_41}, language = {EN}, location = {Reykjavik, Iceland}, talkdate = {2017.01.04}, talktype = {registered}, url = {https://link.springer.com/chapter/10.1007/978-3-319-51814-5_41#copyrightInformation} }
