利用提升小波的方法进行烟雾检测，效果很好-Using wavelet methods to enhance smoke detection, good results

这是基于opencv的烟火检测源代码，很有效的检测火焰和烟雾。-This is based on the opencv fireworks detection source code, it is effective to detect the flame and smoke.

利用opencv实现烟雾检测，利用的特征是：在［0.625Hz，2.5Hz］带宽的频率范围内，监 测图像序列的灰度值通过一个二阶的滤波器后，子信号的频率值的变化，观察其峰峰值的个数，当峰值个数超过2次的时候即可判定为烟雾点-Smoke detection using opencv realized, is characterized by the use: In the [0.625Hz, 2.5Hz] bandwidth, frequency range, the gray value o
