火災容易造成重大傷亡與損失，因此一套良好的火焰偵測系統是有必要的。本論文採用結合傳統影像處理所用的色彩擷取火焰像素和飽和度變化量的關係，進行火焰的判斷和確認位置。其處理流程如下，首先將影像進行火焰像素的擷取，將火焰像素組成一個區域進行分析，利用火焰的飽和度特性進行區域內的標記，透過標記的位置來分辨火焰且定位出火焰在影像中的位子。

The fire accident causes economical damage as well as endangering the life of people, so a set of good system of fire detection is necessary. In this thesis, we will combine traditional image process in fire detection and relation of the variation of saturation for flame to deal with fire recognition and fire location. It deals with procedure as follows. First, extraction of the fire pixels in image, and to analyze the region from fire pixels, to label the saturation for fire region by the property of saturation for flame, recognition of fire and orientation of fire location.
