基于形态学处理和最小二乘法的海天线检测算法

Detection Technique for the Sea-Sky-line Based on Morphological Processing and Least Square Method

海天线的检测和提取是舰船红外图像处理中的一个重要内容,在综合分析比较基于边缘检测、图像分割以及小波变换多尺度分析等多种海天线检测算法优缺点的基础上,提出一种基于形态学处理和最小二乘法的算法,仿真分析表明此算法能适应含有各种干扰的海面背景环境,鲁棒性好,并且提取精度高,能精确定位海天线。

The Sea-Sky-line detection is an important component involved in the warship image processing. This paper introduces some existing algorithms based on linear fit, the Canny operator, the image-division and multi scale analysis of wave let, which are used widely at home and abroad. The paper also analyzes the advantages and disadvantages of these algo rithms. The paper comes up with an improved algorithm based on morphological processing, which keeps the both advanta ges of high accuracy and good rebustness.
