摘要:

为了逃避基于文本的垃圾邮件系统的检测,越来越多的垃圾邮件制造者将文本信息嵌入到图像中。为了有效地检测出图像型垃圾邮件,提出了一种基于灰度—梯度共生矩阵(GGCM,gray-gradient co-occurrence matrix)的图像型垃圾邮件识别方法。先通过灰度—梯度共生矩阵提取图像的特征信息,然后运用最小二乘支持向量机(LS-SVM,least squares support vector machines)进行分类。实验表明,该方法具有较高的分类精度和较好的实时性。

Abstract:

In order to avoid the detection of the spam system based on text,more and more spammers have embedded text information into the image.An image spam identification method based on gray-gradient co-occurrence matrix (GGCM) was proposed to detect image spam effectively.The feature of image was extracted through GGCM firstly,and then LS-SVM was used to do classification.The test results show that this method has higher classification accuracy and better real-time performance

Key words: image spam, gray-gradient co-occurrence matrix, LS-SVM, texture feature
