Before revision:  In this paper , we describe the DAISY system, enabled by established machine learning techniques and physics models, that can localize the shooter location only based on a couple of user-generated videos that capture the gun shot sound . The DAISY system utilizes machine learning techniques like video synchronization and gunshot temporal localization URLanize the unstructured social media videos and quickly localize gunshot in the videos.
After revision:  In this paper , we describe a newly developed tool, the Video Event Reconstruction and Analysis (VERA) system, that enables the localization of a shooter from just a few videos that include the sound of gunshots using established machine learning techniques like video synchronization and gunshot temporal localization URLanize the unstructured social media videos and quickly localize gunshot in the videos.
