چکیده
This paper presents one of the rst investigations of the use of Hidden Markov Models (HMMs) for content-based video indexing. A real-time video indexing system for TV news is described, which is able to distinguish between six diierent classes. The huge potential of these methods for video indexing of movies and TV shows is demonstrated by presenting the rst very promising results.

Content-based video indexing of TV broadcast news using hidden Markov models
This paper presents a new approach to content-based video indexing using Hidden Markov Models (HMMs). In this approach one feature vector is calculated for each image of the video sequence. These feature vectors are modeled and classified using HMMs. This approach has many advantages compared to other video indexing approaches. The system has automatic learning capabilities. It is trained by pr...

This thesis has focused on the automatic video indexing of sports video, and in particular the sub-domain of football. Televised sporting events are now commonplace especially with the arrival of dedicated digital TV channels, and as a consequence of this, large volumes of such data is generated and stored online. The current process for manually annotating video files is a time consuming and l...
متن کاملA new approach to wind turbine power generation forecasting, using weather radar data based on Hidden Markov Model
The wind is one of the most important and affecting phenomena and is known as one of the significant clean resources of energy. Apart from other atmospheric parameters, the wind has complex behavior and intermittent characteristics. Local phenomena can be accompanied by the wind, which is strong, non-predicted, and damaging. Weather radars are capable of detecting and displaying storm-related ...
متن کاملSemantic Indexing of Multimedia Content Using Visual, Audio, and Text Cues
We present a learning-based approach to the semantic indexing of multimedia content using cues derived from audio, visual, and text features. We approach the problem by developing a set of statistical models for a predefined lexicon. Novel concepts are then mapped in terms of the concepts in the lexicon. To achieve robust detection of concepts, we exploit features from multiple modalities, name...
