A New Global Motion Estimation Algorithm and its Application to Retrieval

Abstract- In this paper, we propose a novel global motion estimation technique based on weighted gradient and Displaced Frame Difference (DFD) associated with Wiener es-timation. Then, we apply this technique to parse events of a high level of understanding in a cricket game. A user oriented analysis of the game then reveals a distinct connection between the global motion and specific events. By estimating global motion and analysing the temporal evolution of the estimated motion parameters, we present an effective pro-cess for the extraction of cricket events, leading to a succes rate of 88.9%
