Abstract :
We present a novel algorithm for automated video production based on content ranking. The proposed algorithm generates videos by performing camera selection while minimizing the number of inter-camera switch. We model the problem as a finite horizon Partially Observable Markov Decision Process over temporal windows and we use a multivariate Gaussian distribution to represent the content-quality score for each camera. The performance of the proposed approach is demonstrated on a multi-camera setup of fixed cameras with partially overlapping fields of view. Subjective experiments based on the Turing test confirmed the quality of the automatically produced videos. The proposed approach is also compared with recent methods based on Recursive Decision and on Dynamic Bayesian Networks and its results outperform both methods.
