Police Use of Force Escalation and De-escalation: The Use of Systematic Social Observation With Video Footage

Police Quarterly, 2021
As police agencies continue to incorporate body-worn cameras, it becomes increasingly important for researchers and practitioners to explore how to best use these data to better understand patterns of suspect and police behavior. Thus, drawing on a joint

Video-Based Cryptanalysis: Extracting Cryptographic Keys from Video Footage of a Device’s Power LED Captured by Standard Video Cameras

IEEE Symposium on Security and Privacy
In this paper, we present video-based cryptanalysis, a new method used to recover secret keys from a device by analyzing video footage of a device’s power LED.

3D Reconstructions Using Unstabilized Video Footage from an Unmanned Aerial Vehicle

Journal of Imaging, 2017
Structure from motion (SFM) is a methodology for automatically reconstructing three-dimensional (3D) models from a series of two-dimensional (2D) images when there is no a priori knowledge of the camera location and direction.

Modern, Decentralized Blockchain-Based Solutions for Saving Video Footage

Symposium on Intelligent Systems and Informatics, 2020
The decentralized, cloud-based data storage spaces provide greater data security compared to centralized cloud-based data storage spaces, as the data is not kept at extensive giant servers, like at Amazon, Google and Microsoft, instead, the data is ...

Searching Objects in a Video Footage

International Journal of ICT Research in Africa and the Middle East, 2019
Due to the increase in video content being generated from surveillance cameras and filming, videos analysis becomes imperative. Sometimes it becomes tedious to watch a video captured by a surveillance camera for hours, just to find out the desired footage.

Human Detection and Tracking on Surveillance Video Footage Using Convolutional Neural Networks

Asia Pacific Symposium on Intelligent and Evolutionary Systems, 2019
Safety is one of basic human needs so we need a security system that able to prevent crime happens. Commonly, we use surveillance video to watch environment and human behaviour in a location. However, the surveillance video can only used to record images

Video Analysis of a Snooker Footage Based on a Kinematic Model

2014
Taking an inspiration from psychological studies of visual attention, the contribution of this paper lies in prediction of the critical points of the trajectory using the structure of a scene and physical motion model. On one side, we present our approach for video analysis that differs from traditional tracking techniques by predicting future states ...
