摘要
文章针对舰船热尾流红外图像难以识别的特点,将频域高斯高通滤波技术与空间域直方图均衡技术相结合,对红外图像进行优化处理,锐化了舰船热尾流的边缘,为红外探测潜艇提供了科学的水面热轨迹情况的依据。
Aiming at the infrared image of thermal wake of ship which is hard to be discriminated, this paper optimized the image and protruded the edges of the thermal wake of ship by combining the Frequency GHPF and intensity equilibrium in space. So, scientific bases are available for the infrared detection of submarines.
