A genetic approach to Markovian characterisation of H.264 scalable video [PDF]
, 2011 We propose an algorithm for multivariate Markovian characterisation of H.264/SVC scalable video traces at the sub-GoP (Group of Pictures) level. A genetic algorithm yields Markov models with limited state space that accurately capture temporal and inter ...

Photochemical Fuel Carrier Molecules for Robotic Embodied Energy
Advanced Materials, EarlyView.We designed a novel fuel carrier photoresponsive molecule for on‐demand energy storage and release. Carrier molecules undergo bond scission under UV light to release chemical fuel and locally generate propulsive Marangoni flows. We demonstrate this photochemical embodied energy strategy in small‐scale robots and active matter systems, enabling ...

Markovian Characterisation of H.264/SVC scalable video [PDF]
, 2008 In this paper, a multivariate Markovian traffic: model is proposed to characterise H.264/SVC scalable video traces. Parametrisation by a genetic algorithm results in models with a limited state space which accurately capture.

H4VDM: H.264 Video Device Matching
, 2023 Methods that can determine if two given video sequences are captured by the same device (e.g., mobile telephone or digital camera) can be used in many forensics tasks. In this paper we refer to this as "video device matching". In open-set video forensics scenarios it is easier to determine if two video sequences were captured with the same device than ...
