> 中文摘要: 视频烟雾检测具有响应速度快、非接触等优点,但由于烟雾形状、色彩、纹理千差万别,目前的算法很难取得令人满意的检测效果.为此,提出了一种鲁棒的特征提取方法,采用支持向量机(support vector machine,简称SVM)进行检测.首先,提取边缘方向直方图(edge orientation histogram,简称EOH).然后,采用圆周平移方式将EOH的最高柱变换到EOH的固定位置,消除了旋转变换的影响.为了进一步增强特征的鲁棒性,提取图像亮度和饱和度分量的Hu不变矩、均值、偏差、偏度和峰度特征.最后,将这些特征组成一个38维的特征矢量,采用SVM训练和识别烟雾.实验结果表明,这些特征具有很好的分类性能,能够在较大的训练库和测试库上达到98%和85%以上的检 测率.
Abstract:Video smoke detection has many advantages such as fast response and non-contact. Due to large variance of smoke shape, color and texture, it's difficult for existing methods to achieve satisfactory results. This paper proposes a robust feature extraction method by using support vector machine (SVM) for classification. First, an edge orientation histogram (EOH) is extracted. Then, circular shift technique is used to transform the maximum value bin of EOH to the fixed bin of EOH, thus eliminating the influence of rotation. To further enhance the robustness of features, Hu invariant moments, mean, deviation, skewness, and kurtosis are extracted from both illuminance and saturation component images converted from original RGB images. Finally, all the features are combined together to form a 38-dimentional feature vector, and SVM is used to train and classify smoke images. Experiments show that the features have good discrimination capabilities, and the method can achieve about 98% and 85% detection rates on selected large training and testing data sets.
