| 摘 要： | 为提高烟雾识别的检测率和降低误报率,首先提出了基于置信水平的局部三值模式(CLLTP),进而提出了基于CLLTP的组合特征模型(M_CLLTP)。CLLTP是依据差分图像的像素值呈正态分布而提出的一种改进的局部三值模式。M_CLLTP模型提取了原图的CLLTP特征、Gabor特征图的加权的CLLTP特征和边缘特征图的CLLTP特征,并融合它们生成M_CLLTP特征。对比实验显示,M_CLLTP方法在三个烟雾数据集上都获得了较高的检测率和F1分数、较低的误报率,在两个纹理数据库上获得了最高的平均召回率。实验结果表明,所提方法对烟雾和纹理具有很好的辨识能力,非常适用于烟雾识别。

| Abstract: | To improve detection rate and reduce false alarm rate for smoke recognition,this paper presents local ternary pattern based on confidence level(CLLTP),and further presents a novel multi-CLLTP(M_CLLTP)feature extraction model based on CLLTP.CLLTP is an improved local ternary pattern according to the normal distribution of the pixel values on the difference images.M_CLLTP model computes the CLLTPs for the original images,the weighted CLLTPs for the Gabor feature maps and the CLLTPs for the edge feature maps,and then concatenates the three CLLTP features to generate M_CLLTP feature.Comparative experiments show that M_CLLTP method achieves higher detection rates,lower false alarm rates and higher F1scores on three smoke datasets,and the highest mean recall rates on two texture databases.Experimental results indicate that the presented method has a good discriminative ability for smoke and texture,and is very suitable for smoke recognition. |
