一、概要利用计算机进行数字图象处理的技术已经问世,图象处理被广泛地用在遥感、医疗、工业等方面。在遥感技术方面,1976年美国发射地球观测卫星“LANDSAT-1”(陆地卫星-1)之后,使人们对地球表面的动人景色和卫星图象数据的利用研究引起了重视。后来,到发射“LANDSAT-5”时,开始用新的遥感器“TM”进行观测,收到了更精确的地球表面的图象数据,也可以接收气象卫星“NOAA”(诺阿)的图象数
I. Overview Computer-based digital image processing technology has come out, image processing is widely used in remote sensing, medical, industrial and so on. In the field of remote sensing, the launch of the Earth observation satellite “LANDSAT-1” (Earth Landsat-1) by the United States in 1976 brought much attention to the study of the moving scenery of the Earth’s surface and the utilization of satellite image data. Later, when LANDSAT-5 was launched, observations began with the new remote sensor “TM” and received more accurate image data of the Earth’s surface as well as images of the weather satellite “NOAA” number
