火焰图像特征在火灾数字图像识别中的运用

The Use of Fire Images' Characters in the Distinguishing of the Earlier Fire

火焰尖角数目和圆形度是早期火灾火焰的主要特征,本文主要论述了如何在数学形态学基础上,利用火灾火焰的两个特点判断和识别早期火情。实验中,对火焰的二值图像进行开运算,即先腐蚀,再膨胀,目的是为了对火焰图像进行形态学滤波,去噪。从实验结果可以看出,该算法可以很好的识别火焰和干扰源。

The paper mainly talked about the features of early fire. Processing has been done to the collected earlier fire image by mathematics morphology. In the experiment, opening arithmetic ways has been used in the fire images which is erosion first and dilation second. By this way we can eliminate the most of noises effectively. From the result of the experiment, it is proved that mathematics morphology can help us identify fire and disturbs.
