摘 要
本文主要介绍了基于背景模糊模型的烟雾检测内容，通过小波变换，比较
背景复合图像能量值和出现烟雾时的复合图像能量值，并设定一定的阈值来检
测出烟雾的存在。因此本文将要依次介绍背景图像地提取、小波变换的过程、
阈值的选择以及烟雾的标记过程等内容。并且在文章后面还会提到如何进行改
进，以及部分改进的结果。
关键词：背景模糊，烟雾检测，小波变换，复合图像能量值，阈值
Smoke detection based on background fuzzy model
ABSTRACT
This article mainly introduced the content of smoke detection based on
background of fuzzy model, through wavelet transform, compare the composite image
energy value and the background of smoke composite image of energy value, and set
a certain threshold to detect the presence of smoke. In this paper, we will introduce
the background image extraction, the process of wavelet transform, the selection of
threshold value and the process of marking the smoke. And you'll see how you can
make improvements and some of the improvements later in the article.
Key words: Background blur, smoke detection, wavelet transform, composite
image energy value, threshold value.
