摘要: 在传统的图像型火灾探测中,对火焰颜色、边界等空间域特征进行识别的频率域方法研究较少。为此,提出一种基于边界链码有序数组幅度谱分析的图像型火灾探测算法。该算法将图像中目标轮廓的边界链码变换为有序数组,并对有序数组进行频域变换,获得其幅度谱分布。分析信号的频率域,得到图像空域特征与频域频谱分布之间的联系。将边界链码幅度谱分析理论应用于图像型火灾探测,并通过仿真实验验证了该算法的有效性。

Abstract: Most traditional image fire detection technologies detect fire based on flame space feature such as flame color, boundary and so on, studies lack in image frequency domain. So an image fire detection algorithm based on Amplitude spectrum of boundary chain-code is presented. It converts the chain-code to a sequence array and obtains the amplitude distribution with FFT, analyzes the frequency domain of the image and obtains the relationship of spatial domain features and frequency domain distribution. Amplitude spectrum of boundary chain-code analysis is applied in the research of the image fire detection. Simulation results show the effectiveness of the algorithm.

Key words: amplitude spectrum of boundary chain-code, Fast Fourier Transform(FFT), image processing, fire detection
