| 摘 要： | 在使用遥感数据提取煤火热异常信息的TAE算法的基础上,根据城市热岛特点对算法进行了改进,提出了针对城市热岛研究的Urban-TAE算法,即U-TAE算法.该算法使用不同范围的滑动窗口来探测整幅图像,根据稳健估计的方法设定地表温度高于全部像元以及窗口内像元温度统计均值+标准差的像元为热异常像元,并将滑动窗口的范围设置在5...

| Abstract: | The urban thermal anomaly extraction(U-TAE) algorithm was proposed for the study of urban heat island,which was evolved from the TAE algorithm for thermal anomalies extraction of underground coal fires.The U-TAE algorithm detects the entire thermal infrared image by moving windows with different sizes,and the key of this robust algorithm was to set up thresholds for pixels with land surface temperatures(LST) higher than mean plus standard deviation.Mean and standard deviation were calculated from all pixels... |
