恒虚警率检测matlab代码-fire-dataAssimilation:在MATLAB中使用数据同化概念实现基于卫星的火灾探测方法
恒虚警率检测matlab代码使用数据同化概念的基于卫星的火灾探测
该软件包包括用于基于卫星的火灾探测方法的MATLAB源代码。
使用数据同化方案和整体预测机制估算像素的背景温度。
在恒定虚警率（CFAR）框架下，得出了观察到的亮度温度与预期背景温度之间差异的阈值。
从Meteosat第二代（MSG）-SEVIRI传感器获取的数据用于此项目。
该软件包实现了三种数据同化方法：
•合奏卡尔曼滤波器（EnKF）
•采样重要性重采样（SIR）
•弱约束的四维变分同化（4D-Var）
数据
可以从[EUMETSAT数据中心]（）获取MSG级别1.5图像数据集。
亮度温度是使用提取的。
以下文件包含IR
