摘　　要：针对多光谱红外舰船图像质量差影响应用性的问题,提出基于视觉传达技术的红外舰船图像多级融合方法。利用多光谱红外热成像仪采集舰船图像数据,对红外舰船图像实施中值滤波处理,增强图像的视觉传达效果。通过非下采样变换方法,将红外舰船图像划分为高频方向子带与低频子带。依据高频子带融合方法和低频子带融合方法,分别融合红外舰船图像的高频方向子带与低频子带。对融合后的高频方向子带与低频子带实施非下采样逆变换处理,获取红外舰船图像的多级融合结果。实验结果表明,该方法可以实现不同光谱频段红外舰船图像的多级融合,融合后图像的互信息量、边缘信息保留量均高于0.7,有效提升红外舰船图像的应用性。Aiming at the problem that the poor quality of infrared ship image affects the application,the multistage fusion method of infrared ship image based on visual communication technology is studied.Multi-spectral infrared thermal imager is used to collect ship image data and implement median filtering to enhance the visual transmission effect of infrared ship image.Infrared ship images are divided into high frequency and low frequency subbands by non-subsampling transform method.According to the high frequency and low frequency sub-band fusion methods,the high frequency direction sub-band and low frequency sub-band of infrared ship image are fused respectively.The fusion of high frequency and low frequency subbands is performed by non-downsampling inverse transformation to obtain the multistage fusion results of infrared ship images.The experimental results show that this method can achieve multi-stage fusion of infrared ship images with different spectral bands,and the mutual information and edge information retention of fused images are both higher than 0.7,which effectively improves the applicability of infrared ship images.
