Methods and prospects of road and linear structure extraction from remote sensing image 从遥感影像提取道路信息的方法评述
That the system can stably track targets at lake test shows the signal micro-structure extraction is effective and can be implemented for engineering application 在湖上试验中,该系统能稳定地跟踪水声目标,这说明信号微结构的提取方法是有效的,适合工程化应用。
The algorinthms of the signal micro-structure extraction as a key part of feature enhancement are mapped into hardware platform to build a real-time target detection system by developing high speed and parallel processing ability of dsp chips of tms320c40 将信号微结构的提取重要环节,利用tms320c40dsp芯片的高速和并行处理能力,完成了算法向硬件平台的映射,构成了实时的目标探测系统。
