Automatic detection and prediction of topic changes through automatic detection of register variations and pause duration
نویسندگان
چکیده
In this article a clustering algorithm, allowing the automatic detection of speakers’ register changes, is presented. Together with automatic detection of pause duration, it has shown to be efficient for the automatic detection and prediction of topic changes. The need to take into account other parameters such as tempo and intensity, in the framework of Linear Discriminant Analysis, is proposed in order to improve the identification of the topic structure of discourse.

Reducing Light Change Effects in Automatic Road Detection
Automatic road extraction from aerial images can be very helpful in traffic control and vehicle guidance systems. Most of the road detection approaches are based on image segmentation algorithms. Color-based segmentation is very sensitive to light changes and consequently the change of weather condition affects the recognition rate of road detection systems. In order to reduce the light change ...
