摘要
Abstract
In this paper,an approach to hierarchical multi-threshold detection of offshore ship targets based on scale-adaptive selection is proposed to address deficiencies in the recognition of TIR remote sensing images due to their characteristic low contrast,striping noise,and low spatial resolution.Scale-adaptive selection is conducted as per the maximum value of the normalized Laplacian of Gaussian for ship target image templates.Then offshore ships are detected through multi-threshold screening of the selected Gaussian multi-scale spatial differences.Finally,experiments are conducted to test the impact of scale selection as well as the blocking method for different types of ship image templates on the separation of ship targets in TIR images.The results show that the proposed approach can filter out similar regions according to template scales and achieve effective detection based on well-selected scale and threshold parameters,with a certain level of noise resistance.关键词
