Application of small and medium wave analysis algorithm for ship image size measurement at sea
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 re-search 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.
