海上舰船图像尺寸测量中小波分析算法的应用

Application of small and medium wave analysis algorithm for ship image size measurement at sea

海上舰船目标识别在海洋监视、军事等多个领域应用广泛,舰船图像尺寸测量是海上舰船目标识别的重要组成部分。本文以舰船遥感图像为研究对象,分析了舰船遥感图像的特点,设计了海上舰船图像尺寸测量流程,重点分析了小波分析技术在图像去噪、图像分割以及尺寸测量中的应用,并使用遥感图像进行了实证研究。通过对小波系数的阈值分割,使用小波分析可以有效对舰船图像完成去噪、分割,并可使用最小外接矩形法完成对舰船图像的尺寸测量。

Ship target recognition is widely used in Marine surveillance,military and other fields.Ship image size measurement is an important part of ship target recognition at sea.This paper takes ship remote sensing images as the research object,analyzes the characteristics of ship remote sensing images,designs the size measurement process of Marine ship images,focuses on the application of wavelet analysis technology in image denoising,image segmentation and size measurement,and uses remote sensing images for empirical research.Through thresholding of wavelet coefficients,the ship image can be denoised and segmented effectively by wavelet analysis,and the ship image can be measured by the minimum external rectangle method.
