摘要
针对海天背景下的目标与背景红外图像对比度差、图像边缘模糊等特点,提出了一种远距离舰船红外图像的识别方法,分析了舰船目标的红外辐射特性,对远距离的舰船红外图像进行了预处理,对图像进行了梯度锐化和拉普拉斯锐化处理。仿真实验结果表明:对于远距离舰船红外图像的识别,先用改进的中值滤波方法进行预处理,再进行拉普拉斯锐化处理,可以达到识别目标的目的。
Aiming at the characteristics such as the low infrared image contrast between target and background,fuzzy image edge in the sea-sky background,this paper presents a kind of method to recognize the infrared images of long-range ships,analyzes the infrared radiation characteristic of ship target,performs the preprocessing to the infrared images of long-range ships,performs the gradient sharpening and Laplacian sharpening to the images.The simulation experiment result shows：for the recognition of infrared images of long-range ships,the improved median filtering method is firstly applied for image preprocessing,then Laplacian sharpening processing is applied,the purpose to recognize targets can be reached.
