基于扩展分形特征的图像型火灾检测

针对火灾检测中存在的不稳定及误判率高的问题，提出一种基于扩展分形特征的图像型火灾检测算法。首先在图像的HSI颜色空间进行火焰疑似区域的分割，然后采用文中提出的扩展分形特征计算方法计算图像扩展分形特征，利用该特征对目标事物对比度和大小尺寸敏感的特性，对火焰区域进行再次分割，得到最后的火焰区域。实验结果表明，该算法运行效率较高、误报率较低，适用于多种场合的火灾检测。

Algorithm for fire detection based on extended fractal feature

Concerning the instability and high rate of erroneous recognition with traditional methods in fire detection. An algorithm for fire detection based on extended fractal feature was proposed. Firstly, fire-like regions was segmented according to H component and I component in HSI color space, Secondly, extended fractal feature was computed, the origin image was segmented according to extended fractal feature again. Finally a fire detection algorithm was provided. Experiments show that the proposed algorithm can detect the fire regions accurately.
