一种基于互相关匹配的空域目标提取方法

研究对空域目标的提取,针对空域目标和背景特殊的灰度差异性对目标进行分离。目标提取是通过图像阈值分割实现的。利用信号中的互相关原理,并结合图形模式识别中配准原理,提出了一种互相关匹配的阈值分割方法。实验结果表明针对于空域目标,该方法能够很好的提取出目标信息。

An Airspace Object Extraction Method Based On Cross-correlation Matching

This paper mainly studies the extraction of high-altitude targets, particularly for airspace object because of the gray level difference of target and background. Object extraction is realize by threshold segmentation. Then this paper proposes a new image thresholding method of cross-correlation matching, which takes advantage of correlation principle and combines with the principle of registration in graphical pattern recognition. Experimental results show that the method can well extract the targets of interest.
