Automatic Detection of Emergency Vehicles
نویسنده
چکیده
− In this paper a simple algorithm to detect an emergency vehicle’s siren using the linear prediction is presented. By measuring the means and variances of the reflection coefficients in a preselected number of successive frames, automatic detection of emergency vehicle’s siren is possible. It has been shown that only two coefficients are enough for successful detection. Due to the simplicity of the algorithm, it can be implemented easily on any Texas Instrument’s TMS DSPs. Keywords− linear prediction, reflection coefficients, pattern recognition. * This research was supported by NASA Grant Number NAG 9-1093.

Traffic management is the critical issue of the road. Traffic lights play an important role in the traffic management. The existing traffic lights follow the predetermined sequence. So these lights are called static traffic lights. These traffic lights are not capable to count the number of vehicles and the priority of the vehicles on intersection point. As a result some vehicles have to wait e...

متن کاملReducing 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 ...
