Abstract
A fire detection system has a video sensor, a processor, and a database. The database has a statistical model representing the characteristics of a fire. The video sensor captures images, and sends the images to the processor. The processor computes statistics on the characteristics of the captured image, and compares it to the statistical model to determine if a fire is present in the captured image.
Claims20
A method comprising:
- capturing a set of training images of a fire;
- modeling said fire for a color channel using Gaussian statistics;
- storing said statistics in a database;
- capturing a second image;
- isolating a block within said second image;
- computing Gaussian statistics for a color channel in said block;
- and
- comparing said Gaussian statistics of said fire with said Gaussian statistics of said block.
5 more elements
An article comprising:
- a processor;
- a video sensor coupled to said processor;
- and
- a memory coupled to said processor, said memory comprising a mean and a variance of color characteristics of a fire, and further comprising logic for comparing said mean and said variance with an image captured by said video sensor.
1 more element
A computer readable medium comprising instructions thereon for executing a process comprising:
- providing Gaussian statistics of a fire for a color channel in a database;
- capturing an image;
- isolating a block within said image;
- computing Gaussian statistics for a color channel in said block;
- and
- comparing said Gaussian statistics of a fire with said Gaussian statistics of said block.
