| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In multimedia event detection, complex target events are detected from a large set of consumer domain videos taken in unconstrained environment. We propose a multimedia event detection method using GMM supervectors and support vector machines (SVMs) with multiple features. A GMM supervector consists of the parameters of a Gaussian mixture model (GMM) which represents the distribution of local features extracted from a clip. GMMs can be regarded as an extension of the Bag-of-Words (BoW) method to a probabilistic framework, and thus, expected to be robust against the data insufficiency problem. In the experiment using the dataset of TRECVID2010 MED task, the performance of the proposed method (mean minimum NDC 0.534) was better than the conventional method based on BoW (0.565). | |
